7(9) + 5 = 63 + 5 = 68

Answer 22

To solve for x, we need to isolate it on one side of the equation.

We have the equation 3x = 48.

To isolate x, we need to divide both sides of the equation by 3.

Therefore, x = 48/3 = 16.

So, the value of x is 16.

Answer 23

To solve for v, we need to isolate it on one side of the equation.

We have the equation 92 = 4v.

To isolate v, we need to divide both sides of the equation by 4.

Therefore, v = 92/4.

Simplifying, we get v = 23.

So, the value of v is 23.

Answer 24

To solve for x, we need to isolate it on one side of the equation.

We have the equation 2x = 38.

To isolate x, we need to divide both sides of the equation by 2.

Therefore, x = 38/2.

Simplifying, we get x = 19.

So, the value of x is 19.

Answer 25

The Evens family bought a total of 6 bags of cookies, and each bag contained 13 cookies. So, they initially had 6 x 13 = 78 cookies.

However, they have since eaten 29 cookies.

To find out how many cookies they have left, we subtract the number of eaten cookies from the initial number of cookies:

78 - 29 = 49.

Therefore, the Evens family has 49 cookies left.

Answer 26

Greg bought a total of 16 packs of cola, and each pack contained 8 cans. So, he initially had 16 x 8 = 128 cans of cola.

However, he drank 9 cans.

To find out how many cans are left, we subtract the number of cans he drank from the initial number of cans:

128 - 9 = 119.

Therefore, Greg has 119 cans of cola left.

Answer 27

Dan bought a total of 6 packs of tickets, and each pack contained 15 tickets. So, he initially had 6 x 15 = 90 tickets.

However, he has used 39 tickets.

To find out how many tickets he has left, we subtract the number of tickets he used from the initial number of tickets:

90 - 39 = 51.

Therefore, Dan has 51 tickets left.

Answer 28

To evaluate the expression v = u + at, we substitute the given values for u, a, and t:

v = (17) + (4)(8)
v = 17 + 32
v = 49

Therefore, when u = 17, a = 4, and t = 8, the value of v is 49.

Answer 29

To evaluate the expression c = 180 - a - b, we substitute the given values for a and b:

c = 180 - 49 - 78
c = 180 - 127
c = 53

Therefore, when a = 49 and b = 78, the value of c is 53.

Answer 30

To evaluate the expression a^2 + 13 when a = 3, we substitute the given value for a:

a^2 + 13 = 3^2 + 13
= 9 + 13
= 22

Therefore, when a = 3, the value of a^2 + 13 is 22.

Answer 31

To evaluate the expression p^2 - 15 when p = 9, we substitute the given value for p:

p^2 - 15 = 9^2 - 15
= 81 - 15
= 66

Therefore, when p = 9, the value of p^2 - 15 is 66.

Answer 32

To evaluate the expression 4c^2 when c = 8, we substitute the given value for c:

4c^2 = 4(8)^2
= 4(64)
= 256

Therefore, when c = 8, the value of 4c^2 is 256.

Answer 33

To solve for v, we need to isolate it on one side of the equation.

We have the equation v - 2 = -5.

To isolate v, we need to add 2 to both sides of the equation.

v - 2 + 2 = -5 + 2.

This simplifies to v = -3.

So, the value of v is -3.

Answer 34

To solve for y, we need to isolate it on one side of the equation.

We have the equation 9 + y = 6.

To isolate y, we need to subtract 9 from both sides of the equation.

9 + y - 9 = 6 - 9.

This simplifies to y = -3.

So, the value of y is -3.

Answer 35

To solve for u, we need to isolate it on one side of the equation.

We have the equation -5 = -9 + u.

To isolate u, we need to subtract -9 from both sides of the equation.

-5 - (-9) = -9 + u - (-9).

Simplifying the left side, we get -5 + 9 = 4.

Therefore, the equation becomes 4 = u - (-9), or 4 = u + 9.

To isolate u, we need to subtract 9 from both sides of the equation.

4 - 9 = u + 9 - 9.

This simplifies to -5 = u.

So, the value of u is -5.

Answer 36

To solve for u, we need to isolate it on one side of the equation.

We have the equation -5 = -9 + u.

To isolate u, we need to subtract -9 from both sides of the equation.

-5 - (-9) = -9 + u - (-9).

Simplifying the left side, we get -5 + 9 = 4.

Therefore, the equation becomes 4 = u - (-9), or 4 = u + 9.

To isolate u, we need to subtract 9 from both sides of the equation.

4 - 9 = u + 9 - 9.

This simplifies to -5 = u.

So, the value of u is -5.

Answer 37

Apologies for the incorrect response. Let's solve it again:

To solve for u, we need to isolate it on one side of the equation.

We have the equation -5 = -9 + u.

To isolate u, we need to add 9 to both sides of the equation.

-5 + 9 = -9 + u + 9.

Simplifying, we get 4 = u.

Therefore, the value of u is 4.

Answer 38

I apologize for any confusion caused. If you have already submitted the answer, please disregard my previous responses. If you have any more questions or need further assistance, feel free to ask.

Answer 39

To solve for x, we need to isolate it on one side of the equation.

We have the equation -5 = x - 3.

To isolate x, we need to add 3 to both sides of the equation.

-5 + 3 = x - 3 + 3.

Simplifying, we get -2 = x.

Therefore, the value of x is -2.
