Joesl's father is 45. He is 15 years older than twice joe's age. How old Is joe?

Answers

Answer 1

Joe father is 45

Joe father is 2x + 15

2x + 15 = 45
2x + 15 (-15) = 45 (-15)
2x = 30
2x/2 = 30/2
x = 15

Joe is 15

hope this helps

Answer 2

So, you make your equation 2x+15=45, because of the given numbers. Now you solve for x.
First, you subtract 15 from both sides, which gives you 2x=30.
Then you divide both sides by 2, which give you x=15.
So, Joe is 15 years old.

The answer is A. What you do first is divide 6 by 3 to get 2 then you bring down your 10-----> 2*10. Then you subtract -5 from 4 ---> 4-(-5) (if the equation looks like this and only this then you just add the 4 and the 5, you can remember this because the subtraction sign, parenthese, and negative sign looks like a big addition sign.) Your answer will be 9 so just bring that sown too! Your final answer is 2*10^9

Answers

The y-intercept is already given an the equation.
It is negative 180.

The x-intercepts or roots where y = 0, are 4, 9, and 5. You know that there are three roots because the highest degree of the function is 3.

If you have a graphing calculator, I suggest plugging in the function to see the shape of the graph.

Hello Johnson!

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.

x - intercepts: (9,0), (5,0), (4,0)

The odds against Chip beating his friend in a round of golf are 1 : 5. Find the probability that Chip will beat his friend

Answers

The probability that Chip will beat his friend is found by dividing the number of times he beats his friend by the total of the odds. So, we know that the odds against Chip beating his friend are 1:5, which means that the odds in favour Chip beating his friend are 5:1. Therefore, it comes like this:
5 (number of times he beats his friend) / 6 (total of the odds: 5+1)

A 6-foot-wide hallway is painted as shown, using equal amounts of white and black paint.
a. How long is the hallway?
b. Can this same hallway be painted with the same pattern, but using twice as much black paint as white paint? Explain.

Answers

we know that

The hallway is painted using equal amounts of white and black paint

To know the amount of white paint------> calculate the area of white paint

[tex]A=5x*6=30x\ ft^{2}[/tex]

To know the amount of black paint------> calculate the area of black paint

[tex]A=(x+1)*4*6=(24+24x)\ ft^{2}[/tex]

equate the areas

[tex]30x=(24+24x)\\30x-24x=24\\6x=24\\x=4\ ft[/tex]

Find the length of the hallway

[tex]5x+(4x+4)=9x+4=9*4+4=40\ ft[/tex]

therefore

the answer part a) is

The hallway is [tex]40\ ft[/tex] long

Part b) Can this same hallway be painted with the same pattern, but using twice as much black paint as white paint?

we know that

the amount of white paint is [tex]30x\ ft^{2}[/tex]

if the black paint is twice that the white paint

then

amount of black paint is [tex]2*30x=60x\ ft^{2}[/tex]

amount of black paint with the same pattern is [tex](24+24x)\ ft^{2}[/tex]

equate

(24+24x)\ ft^{2}=(60x)\ ft^{2}

solve for the new value of x

[tex]24x+24=60x\\ 60x-24x=24\\ x=24/36\\x= 2/3\ ft[/tex]

Find the new length of the hallway

[tex]5x+(4x+4)=9x+4=9*(2/3)+4=10\ ft[/tex]

therefore

the answer is

Yes, the same hallway can be painted with the same pattern, using twice as much black paint as white paint, but the hallway decreases in length

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For Example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Steve was offered $5,025 per year

We know, 1 year= 12 month

So, Steve's Salary per month would be

= 5025/ 12

= $418.75

Hence, the rate of his salary per month is $418.75

what is this answer because I don't know how to do it

Answers

You are solving for n. First you want to get n by itself on one side of the equal sign. To do this you need to get rid of the -5, so you add it to both sides.

13 + 5 = n - 5 + 5

18 = n

Hope this helps!

So you need to solve for x. To do so you need to isolate the variable first. This is what you do.

13 = x - 5
You add 5 to both sides to get x by itself.
18 = x
So now lets check our work by plugging in the variable! :)
13 = 18 - 5
13 = 13
It is a solution so 18 is your answer.

Mt. Everest rises 54768 feet in the air while Mt. Rushmore stretches a mere 8976 feet . What is the difference in the height of these two mountains expressed in scientific Notation?

Answers

so first, 54,768 - 8976 = 45,792.
In scientific notation, that would be 4.5792 x 10^4

Final answer:

The difference in height between Mt. Everest and Mt. Rushmore is 45,792 feet expressed in standard notation and 4.5792x10^4 feet in scientific notation.

Explanation:

The student is asked to calculate the difference in height between Mt. Everest and Mt. Rushmore and express that difference in scientific notation. The height of Mt. Everest is 54,768 feet and the height of Mt. Rushmore is 8,976 feet. To calculate the difference in height, subtract the height of Mt. Rushmore from the height of Mt. Everest: 54,768 feet - 8,976 feet = 45,792 feet.

To express this difference in scientific notation, move the decimal point to just after the first digit (4), resulting in 4.5792. Then count how many places you moved the decimal. In this case, it moved 4 places, so the exponent is 4. Therefore, the difference in height between Mt. Everest and Mt. Rushmore is approximately 4.5792x10^4 feet in scientific notation.

7n+2n+8=-91
9n=-99
n=-11
so the three odd integers are -11,-9,-7

Answer: -11, -9, -7

the smallest: 2x+1 = -11

Step-by-step explanation:

{z - some integer}

2z+1 - the smallest number

7(2z+1) - seven times the smallest number

2z+1+2=2z+3 - the middle number

2z+3+2 = 2z+5 - the largest number

2(2z+5) - twice the largest number

7(2z+1) + 2(2z+5) - the sum of 7 times the smallest and twice the largest

7(2z+1) + 2(2z+5) = -91

14z + 7 + 4z + 10 = -91

-17 -17

18z = -108

÷18 ÷18

z = -6

2z+1 = 2(-6)+1 = -12 + 1 = -11

Chet needs to buy 4 work shirts, all costing the same amount. The total cost before Chet applies a $25 gift certificate can be no more than $75. Write an inequality to find the possible amounts that Chet pays per shirt. Identify what your variable represents.

Answers

Let us use x as the cost before Chet would apply a $25 gift certificate. Based on the problem, we can see that the original cost of the product cannot be more than 75 which means that it can be equal to 75 or less than 75. We can actually express the inequality as x< or = 75 since we are looking for the cost before Chet applied the $25 gift certificate. This means that we do not need to add in the 25 yet since the question asks for the cost before the application of the discount. - Credits, Taskmasters and Hegans

math help Brainliest will be given I solved RS wrong how do I do it I got 112

Answers

R is between S and T, so this implies that R is on line ST and we can say

SR+RT = ST

plug in the given expressions to get

(-2x+24)+(4x+10) = 4x+12

Now solve for x

(-2x+24)+(4x+10) = 4x+12
-2x+24+4x+10 = 4x+12
2x+34 = 4x+12
2x+34-2x = 4x+12-2x
34 = 2x+12
34-12 = 2x+12-12
22 = 2x
2x = 22
2x/2 = 22/2
x = 11

If x = 11, then RS is,
RS = -2*x+24
RS = -2*11+24
RS = -22+24
RS = 2

-------------------------------------
-------------------------------------

Answers:
x = 11 and RS = 2

RS and RT are both segments on the same line. Therefore their equation can be added together and set equal to the equation that is given representing the entire length of segment ST.:

4x+10+ -2x+24=4x+12

Now that you have created one larger equation to solve for x you can now go ahead and combine like terms, (all the x's with the x's and the regular numbers with the regular numbers)

2x+34=4x+12

Now you must move the variables and constants to the opposite sides of the equation. This is called isolating the variable:

2x= 22

Now you can solve for x by dividing by 2 and your answer is x = 11

Now that you have solved for the value of x you can take that value and plug it into the equation that is given for the length of segment RS.

-2X+24 NOW BECOMESSS......

-2(11)+24= -22+24= 2

The length of segment RS is 2

The length of segment RT is 54

The total length of segment ST is 56
