You purchased 132.49 dollars worth of wheels and bearings for your skateboards. The shop charges 15 dollars per board to install them. The total cost is 192.49 dollars. How many skateboards will be repaired?

Answer: 2x+4

Subtract the equations like so

f - g = (4x+3) - (2x-1)

f - g = 4x+3 - 2x + 1 ... distribute the negative to all terms inside parenthesis

f - g = (4x-2x) + (3+1)

f - g= 2x + 4

Answer:

y+3 = 4(x+1)

Step-by-step explanation:

Point slope form of a line is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point

y--3 = 4 (x--1)

y+3 = 4(x+1)

Answer:  plot slope form is y+3= 4(x+1)

                                    or

                     y = 4x+1

Step-by-step explanation:

Slope point form of equation is given by

    y-y1 = m (x-x1)

           where m is slope and (x1,y1)  is the point

here (point) is (-1,-3)  and slope = 4

so equation is

(y - (-3) )= 4 ( x -(-1))

y+3 = 4(x+1)

y+3 = 4x+4

y = 4x +1

Answer:

D) 11/15

Step-by-step explanation:

11/15 is the doble amount of 5.5/7.5, but is the same number if you divide it.

The ratio of the width to the length of the swimming pool with a width of 5.5 yards and a length of 7.5 yards is 11/15 yards, which corresponds to answer D) 11/15 yards.

The student has asked to find the ratio of the width to the length of a rectangular swimming pool where the width is 5.5 yards and the length is 7.5 yards. To find this ratio, we divide the width by the length:

Ratio = Width / Length = 5.5 yards / 7.5 yards. Simplifying this we get:

Ratio = 11/15 yards.

Therefore, the correct answer is D) 11/15 yards.

Answer:

28 < x < 114

Step-by-step explanation:

Problem 7 is choice B, which is the entire number line shaded in but the value -4 has a hole at this location to mean "exclude this point from the solution set". So basically x can be any number but -4.

Problem 8 is choice C. You have a closed circle (or filled in hole) at -1.5 on the number line. Then you shade to the left of the closed circle to indicate the set of values that are smaller than this endpoint. So n can be -1.5 or it can be smaller than -1.5 (something like -2 or -3, etc).

Answer:

f(-2) = 4

f(0) = 6

f(5) = 11

Step-by-step explanation:

f(x)=x+6 when x = -2

Substitute x=-2

f(-2) = -2+6

f(-2) = 4

f(x)=x+6 when x = 0

Substitute x=0

f(0) = 0+6

f(0) = 6

f(x)=x+6 when x = 5

Substitute x=5

f(5) = 5+6

f(5) = 11

Answer:

the distance is 14

Step-by-step explanation:

To find the distance between 2 points, we can use the distance formula

d = sqrt( (x2-x1)^2 + (y2-y1) ^2 )

d = sqrt( (-3--3)^2 +(-9-5) ^2 )

= sqrt( (-3+3)^2 + (-14)^ 2)

= sqrt(0^2 +14^2)

= sqrt( 14^2)

Answer:

Numbers are divisible by 9 if the sum of all the individual digits is evenly divisible by 9

Step-by-step explanation:

5+3+6+4 = 18

18 is divisible by 9 so therefore, those numbers are monomials of the number 9.

Monomials that are divisible by 9 are those whose numeric coefficient is divisible by 9. For example, the monomial 27x or 81y^2 are both divisible by 9 because their numeric coefficients (27 and 81, respectively) are divisible by 9.

In mathematics, a monomial is an algebraic expression consisting of one term. Monomials that are divisible by 9 are those whose numeric coefficient is divisible by 9. For example, if you have a monomial like 27x, you can check if it's divisible by 9 by dividing the numeric coefficient (27) by 9. Since 27 divided by 9 is equal to 3, you can conclude that 27x is divisible by 9. Another example would be 81y^2 where the numeric coefficient is 81. Because 81 divided by 9 equal to 9, 81y^2 is also divisible by 9. So any monomial with a numeric coefficient that is a multiple of 9 is divisible by 9.

Answer:

Each lemon costs $1.70. Each plum costs $3.70.

Step-by-step explanation:

You have two unknowns and two statements about costs. First, define a variable for each unknown. Then, translate the statements about the costs into two equations. Then, solve the system of equations.

Let L = price of 1 lemon

Let P = price of 1 plum

Donata:

4 lemons and 4 plums for $21.60

4L + 4P = 21.6      Equation 1

Dan:

11 lemons and 6 plums for $40.90

11L + 6P = 40.9       Equation 2

Here is the system of equations.

4L + 4P = 21.6      Equation 1

11L + 6P = 40.9       Equation 2

Divide both sides of Eq. 1 by 4.

L + P = 5.4

Multiply both sides by -6.

-6L - 6P = -32.4

Add the equation above to the Eq. 2.

5L = 8.5

L = 8.5/5

L = 1.7    <-------  price of a lemon

L + P = 5.4

1.7 + P = 5.4

P = 3.7    <------   price of a plum

Each lemon costs $1.70. Each plum costs $3.70.

Answer:

So if sarah feeds her fish every two days, youd divide each number by 30. So the fish would be fed 15 times and the snake 5 times. Hope you get it correct! Good Luck!

Answer: hello mate!

Sara feeds her fish every 2 days: this means that if we took the 0 in a day that she feed both animals; then the fish gets food on the day 2, on the day 4, on the day 6, etc

And the snake gets food on days 6, 12, 18, etc.

now we want to count the number of days where both animals get food on the same day. Because 6 is a multiple of 2, we can see that every day that the snake is feed, the fish also feed, this is because the minimal common multiple between 2 and 6 is 6.

then we can see that each 6 days Sarah feeds her fish and snake on the same day. Now we need to see the number of times that this event happens in 30 days; we can see this dividing 30 days by  6 days:

30/6 = 5

Then in the span of 30 days, there are 5 times where both animals get food on the same day.

Answer:

The answer is -x^4, Good Luck!

Step-by-step explanation:

(3x^4+2x^2-6) - (4x^4+2x^2-6) = -x^4

To subtract (3x^4+2x^2-6) from (4x^4+2x^2-6), subtract the corresponding terms and keep the same variable raised to the same power. For example, subtracting 3x^4 from 4x^4 gives us x^4. Therefore, the result is x^4.

To subtract (3x^4+2x^2-6) from (4x^4+2x^2-6), we need to subtract the corresponding terms. So, subtract the coefficients of like terms. For the terms with variable x raised to a power, subtract the coefficients and keep the same variable raised to the same power. For the constant term, subtract the constants.

For example, subtracting 3x^4 from 4x^4 gives us (4x^4 - 3x^4) = x^4. Subtracting 2x^2 from 2x^2 gives us (2x^2 - 2x^2) = 0. Subtracting 6 from 6 gives us (6 - 6) = 0.

Therefore, the subtraction of (3x^4+2x^2-6) from (4x^4+2x^2-6) results in x^4 + 0 + 0 or simply x^4.

Answer:

$6.79

Step-by-step explanation:

We need to find the cost of a bottle of soap.  We divide the cost by the number of bottles

$9.12/6 = $1.52 per bottle

We also need to find the cost for a sponge

$5.00/4 = $1.25 per sponge

We want to find the total cost of 2 bottles of soap and 3 sponges

cost = 2 * 1.52 + 3 * 1.25

       = 3.04 + 3.75

     = 6.79

Final answer:

The total cost comes to $6.79.

Explanation:

To calculate the total cost of buying 2 bottles of liquid soap and 3 sponges, we need to first find the cost of a single bottle of soap and a single sponge. We can do this by dividing the total cost of multiple items by the number of items to get the price per item.

The cost of 6 bottles of soap is $9.12. To find the cost of 1 bottle of soap, we divide: $9.12 / 6 = $1.52 per bottle.

The cost of 4 sponges is $5.00. To find the cost of 1 sponge, we divide: $5.00 / 4 = $1.25 per sponge.

Now, we can calculate the cost of 2 bottles of soap: 2 x $1.52 = $3.04.

And the cost of 3 sponges: 3 x $1.25 = $3.75.

Finally, we add the two amounts to find the total cost: $3.04 (soap) + $3.75 (sponges) = $6.79

So, the total cost of buying 2 bottles of soap and 3 sponges is $6.79.

Step-by-step explanation:

Using the provided systems of linear equations method, one bag of regular balloons costs $1.45, and one bag of sparkling balloons costs $2.10.

The subject of this question is a typical example of a system of linear equations. Here, we are given two different purchases which give us two equations. We have:

1) 6B + 5S = 19.20 ---> Eq (1) (where B stands for one bag of balloons and S stands for one bag of sparkling balloons)

2) 8B + 2S = 15.80 ---> Eq (2)

Now, to find the prices of B and S (the number of bags of balloons and bags of sparkling balloons, respectively), we can solve this system of equations in two steps: multiplying Eq (2) by 2.5 and then subtracting Eq (1) from the result. This gives:

20B + 5S = 39.5

Then subtract Eq (1) from this new equation, which yields 14B = 20.3. So, one bag of balloons (B) costs $1.45. Substituting B = 1.45 into Eq (1), we get 6(1.45) + 5S = 19.2, which simplifies to 5S = 10.5. Thus, one bag of sparkling balloons (S) costs $2.10. So, the cost per bag of regular balloons is $1.45, and the cost per bag of sparkling balloons is $2.10, and this is how you go about decorating your gym on a budget.

Answer:

The range of the number of people that are satisfied is option A. 46,968 to 51,912 customers.

Step-by-step explanation:

Hi, to solve this problem you need to calculate the total number of customers that are pleased with the service, based on the 150 people sample.

so:

(72,000 x 103 )÷150 = 49,440

The next step is to calculate the 5% margin of error of that result.

49,440 x 0.05= 2,472

Finally, to obtain the range you need to add and subtract the margin to the total number of customers that are pleased with the service.

49,440-2,472= 46,968

49,440 + 2,472=51,912

So, the range of the number of people that are satisfied is option A. 46,968 to 51,912 customers.
