Question

If 9 is subtracted from two-thirds of a number, the result is 7. Find the number.



the number is 3

the number is 10.67

the number is 24

Answer 1

3

Answer 2

One side of a rectangle is 3 inches shorter than the other side, and the perimeter is 54 inches. What are the dimensions of the rectangle?

Which of the following equations could be used to solve the problem?



2x + 2(x - 3) = 54

2x + 2x - 3 = 54

2x - 3 = 54

Answer 3

Two-thirds of 3 is 2.

Answer 4

WHICH one a b c

Answer 5

2x + 2(x - 3) = 54

Answer 6

A. 2x + 2(x - 3) = 54

Answer 7

The quotient of a number and 2 is the same as the difference of the number doubled and 3. What is the number?



2

-2

-4

Answer 8

2

Answer 9

Two fewer than a number doubled is the same as the number decreased by 38. Find the number.

If n is "the number," which equation could be used to solve for the number?



2(n - 2) = n - 38

2n - 2 = n - 38

2(n - 2) = n + 38

Answer 10

B.

Answer 11

Three-sevenths of a number is 21. Find the number.



the number is 9

the number is 27

the number is 49

Answer 12

49

Answer 13

If 3 times a certain number is increased by 4 the result is 28. What is the number?

If x is "the number," which of the following equations could be used to solve for the number?



3x + 4 = 28

3(x + 4) = 28

3x = 4 + 28

Answer 14

A

Answer 15

Three multiplied by the sum of 4 and a number is the same as 18 more than the number. Find the number.

If n is "the number," which equation could be used to solve for the number?



3n + 4 = n + 18

4(3 + n) = n + 18

3(4 + n) = n + 18

Answer 37

If f(x) = x - 5, then match each of the following.

1. f(-1) 3
2. f(0) 0
3. f(1) -4
4. f(2) -6
5. f(5) -3
6. f(8) -5

Answer 38

1. f(-1) = -1 - 5 = -6
2. f(0) = 0 - 5 = -5
3. f(1) = 1 - 5 = -4
4. f(2) = 2 - 5 = -3
5. f(5) = 5 - 5 = 0
6. f(8) = 8 - 5 = 3
