7-4+6=7 Complete the equation to make it equal

The equation has only one solution, c = 0.

To determine the number of solutions for the given equation, we need to solve it and see if there is a unique solution, infinitely many solutions, or no solution at all.

First, we can simplify the equation by combining like terms:

9c - 10 = -10c - 10

Adding 10c to both sides, we get:

19c - 10 = -10

Adding 10 to both sides, we have:

19c = 0

Finally, dividing both sides by 19, we find the value of c:

c = 0

The equation has only one solution, c = 0.

Answer:

1052

Step-by-step explanation:

The two given boxes for reference are presented below.

Since we know the dimensions of the first container, we can calculate its volume.

[tex]V_1= 5 \text{cm} \cdot 4 \text{cm} \cdot 4 \text{cm} = 80 \text{cm}^3[/tex]

The first container held 192 skittles. Using that fact, now that we know the volume of the first box, we can calculate the volume of a single skittle.

[tex]v = \frac{80}{192} = 0.416 \approx 0.42 \text{cm}^3[/tex]

The second container held 258 skittles.

The volume of the second box is:

[tex]V_2 = 12 \text{cm}\cdot 3 \text{cm} \cdot 3 \text{cm} = 108 \text{cm}^3[/tex]

Using this facts, the volume of a single skittle would be

[tex]v = \frac{108}{258} = 0.418 \approx 0.42 \text{cm}^3[/tex]

Therefore,  the volume of  single skittle is around to 0.42 cm³.

A skittle jar is a cylinder. Its volume is calculated by the formula

[tex]V = r^2h \pi[/tex],

where [tex]r[/tex] is the radius and [tex]h[/tex] is the height. From the given data, we have [tex]r = 3.15 \text{cm}[/tex] and [tex]h = 11.5 \text{cm}[/tex]. Hence, the volume of the jar is

[tex]V = 3.5^2 \cdot 11.5 \cdot 3.14 = 442 \text{cm}^3[/tex]

Now, we can determine the number of skittles in the jar. Let [tex]n[/tex] be the number of skittles in the jar. Then,

[tex]n = \frac{\text{volume of the jar}}{\text{volume of a skittle}} = \frac{V}{v} = \frac{442}{0.42} = 1052.38 \approx 1052\\[/tex]

Final answer:

The best estimate for the number of jelly beans in the jar is approximately 1,000 beans, calculated based on linear dimensions and volume estimation.

Explanation:

The best estimate for the number of jelly beans in the jar would be approximately 1,000 beans.

To estimate this, we first look at linear dimensions and consider a rectangular jar. Assuming the jar is about 10 beans deep, 10 beans wide, and 10 beans high, the volume would be around 10 x 10 x 10, giving us ~ 1,000 beans inside.

For radius x, Choice 'A' π/4 is the correct answer.

For radius 10x, Choice 'B' π/4 is the correct answer.

For radius 100x, Choice 'B' π/4 is the correct answer.

Step-by-step explanation:

The Area of the circle = πr^2, where "r" is the length of the radius.

The Area of square = a^2, where "a" is the length of an edge of a square.

CASE 1 :

Substitute radius r = x and edge length a = 2x,

Area of circle = π*x*x = πx^2

Area of square = 2x*2x = 4x^2

The ratio of the area of the circle to the area of square = πx^2 / 4x^2 = π/4

Choice 'A' π/4 is the correct answer.

CASE 2 :

Substitute radius r = 10x and edge length a = 20x,

Area of circle = π*10x*10x = 100πx^2

Area of square = 20x*20x = 400x^2

Ratio of the area of the circle to the area of square = 100πx^2 / 400x^2

                                                                                         = π/4

Choice 'B' π/4 is the correct answer.

CASE 3 :

Substitute radius r = 100x and edge length a = 200x,

Area of circle = π*100x*100x = 10000πx^2

Area of square = 200x*200x = 40000x^2

Ratio of area of the circle to the area of square = 10000πx^2 / 40000x^2

                                                                                  = π/4

Choice 'B' π/4 is the correct answer.

Answer:

Explanation:

The given information can be summarized in this way:

Following Newton's second law, net force equal mass times acceleration:

To predict the motion, you apply Newton's second law in each direction (vertical and horizontal)

        Net vertical force = 8N - 8N = 0. This means there is not motion in the vertical direction.

         Net horizontal force = 6N - 4N = 2N. This means there is a net force of 2N to the right, which lets you predict that the bone starts to accelerate to the right; this is, the bone begins to move toward the right.

Answer:

Let's use these two sets given to explain what is the domain.

Each value from the left set is x, and from the right is f(x).

If we plug any x from the left set in the function, we'll get f(x)  that corresponds to it and that's exactly what the arrows are showing.

Domain of the function is, basically, a set of all values x can have.

In this case, it's easy to see, those are all members of the left set (-6, 1, 5, 8), but sometimes this set can have lots and lots of members, even infinity.

The value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x) for x=2

Step-by-step explanation:

We have to write the given problem mathematically to solve it

So,

[tex]4(5x-8) = 2(4-x)+4[/tex]

First of all, distributive property will be applied

[tex]20x-32 = 8-2x+4\\20x-32 = 12-2x[/tex]

We have to isolate the variable on one side of the equation

Adding 2x on both sides of equation

[tex]20x-32+2x = 12-2x+2x\\22x-32 = 12[/tex]

Addition property of equality with 32

[tex]22x-32+32 = 12+32\\22x = 44[/tex]

Division Property of Equality (22)

[tex]\frac{22x}{22} = \frac{44}{22}\\x = 2[/tex]

Hence,

The value of the expression 4(5x–8) is 4 more than the value of the expression 2(4–x) for x=2

53926

Step-by-step explanation:

539.26x100=53926

Answer:

part A:

M = 4(2x + 6)

   = 8x + 24

part B:

option 1) i think the x value is equal for both M and N since they have the value 8.

option 2)  If you meant to solve M and N with an EQUATION then here's your answer:

8x+24 = 8x+10

24≠10   (you subtract 8x when taken to the other side)

So, the answer would be NO SOLUTION

Final answer:

To apply the distributive property to expression M, multiply each term inside the parentheses by 4, resulting in M = 8x + 24. Comparing this to expression N, which is N = 8x + 10, one can see that M and N are not equivalent because their constant terms differ.

Explanation:

Part A: Equivalent Expression for M

To find an equivalent expression for M, we use the distributive property which states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. Therefore:

M = 4(2x + 6)

Apply the distributive property to get:

M = (4 × 2x) + (4 × 6)

M = 8x + 24

Part B: Are M and N Equivalent?

To determine if M and N are equivalent expressions, we must compare the expressions that we have for M and N:

M = 8x + 24

N = 8x + 10

Since the coefficients of x are the same but the constant terms are different, the two expressions are not equivalent for any value of x.

Step-by-step explanation:

[tex](+)(+)=(-)(-)=(+)\\(+)(-)=(-)(+)=(-)\\\\-(-x-3)=-1(-x-3)\qquad\text{use the distributive property}\\\\=(-1)(-x)+(-1)(-3)=x+3[/tex]

The correct answer is b = 6 √3 units

Step-by-step explanation:

Let's recall that we can use the following ratio for the sides of a 90 - 60 - 30 triangle:

1 : √3 : 2, where 2 is the hypotenuse.

Upon saying that, we have that in our triangle:

Hypotenuse = 12 units

a = 6 units

b = 6 √3 units

The correct answer is b = 6 √3 units

Answer:

b = 6

Step-by-step explanation:

The above questions is trigonometry where hypothenus = 12; opposite = b; and adjacent = a. Applying SOHCAHTOA principle, the appropriate is

Sine = opposite/hypothesis, since we are to find the value of b. Thus,

Sine 30 = b/12

0.5 =b/12

The given statement, "Deposits of gold can be found in the deep ocean" is true.

Explanation:

According to the report of National Ocean service, oceans have nearly 20 million pounds of gold that are suspended in normal sea water to the tune of parts per trillion. Deep down the ocean floor, larger amount of gold are encased in rocks that could be mined. But mining in the deepest part of the ocean is not much cost efficient and would not bring any profits. Moreover, since gold will not get decomposed by salt water, it stays undisturbed on the ocean floor.

Answer:

The two numbers are 15 and 6.

Step-by-step explanation:

Given:

The difference between two numbers is 9.

The first number plus twice the other number is 27.

Now, to find the two numbers.

Let the first number be [tex]x.[/tex]

And the other number be [tex]y.[/tex]

So, the difference between two numbers is 9.

[tex]x-y=9[/tex]

[tex]x=9+y[/tex]    ............(1)

As, given the first number plus twice the other number is 27.

According to question:

[tex]x+2y=27[/tex]

Substituting the value of [tex]x[/tex] from equation (1):

[tex](9+y)+2y=27\\9+y+2y=27\\9+3y=27[/tex]

Subtracting both sides by 9 we get:

[tex]3y=18[/tex]

Dividing both sides by 3 we get:

[tex]y=6.[/tex]

The other number = 6.

Now, substituting the value of [tex]y[/tex] in equation (1):

[tex]x=9+y\\x=9+6\\x=15.[/tex]

The first number = 15.

Therefore, the two numbers are 15 and 6.
