### -15 + (-7)

• A.

-22

• B.

22

• C.

-8

• D.

8

A. -22
Explanation
The given expression involves adding two negative numbers, -15 and -7. When adding negative numbers, the result is always negative. Therefore, the sum of -15 and -7 is -22.

Rate this question:

### 14 - 24

• A.

-10

• B.

10

• C.

-38

• D.

38

A. -10
Explanation
The given question is asking for the difference between 14 and 24. When we subtract 24 from 14, we get -10. Therefore, the correct answer is -10.

Rate this question:

• 3.

### -8 - 10

• A.

-2

• B.

2

• C.

-18

• D.

18

C. -18
Explanation
The correct answer is -18 because when we subtract a negative number from a negative number, we add the absolute values of the numbers and keep the same sign as the larger number. In this case, -8 - (-10) becomes -8 + 10, which equals 2.

Rate this question:

• 4.

### 5 - (-15)

• A.

-10

• B.

10

• C.

-20

• D.

20

D. 20
Explanation
The given expression is 5 - (-15). When subtracting a negative number, it is equivalent to adding the positive of that number. So, -(-15) becomes +15. Therefore, the expression simplifies to 5 + 15, which equals 20.

Rate this question:

• 5.

### Solve for the variable.27 + n = 42

• A.

N = 69

• B.

N = 25

• C.

N = -15

• D.

N = 15

D. N = 15
Explanation
To solve the equation 27 + n = 42, we need to isolate the variable n. We can do this by subtracting 27 from both sides of the equation. This gives us n = 42 - 27, which simplifies to n = 15. Therefore, the correct answer is n = 15.

Rate this question:

• 6.

### Solve for the variable.n - 20 = 25

• A.

N = 5

• B.

N = -5

• C.

N = 45

• D.

N = -45

C. N = 45
Explanation
The equation is n - 20 = 25. To solve for n, we need to isolate the variable. Adding 20 to both sides of the equation, we get n = 45.

Rate this question:

• 7.

### Solve for the variable.n/6 = 12

• A.

N = 72

• B.

N = -72

• C.

N = 2

• D.

N = -2

A. N = 72
Explanation
To solve for the variable, we need to isolate it on one side of the equation. In this case, we have n divided by 6 equals 12. To get rid of the division, we can multiply both sides of the equation by 6. This cancels out the division on the left side, leaving us with n equals 72. Therefore, the correct answer is n = 72.

Rate this question:

• 8.

### Solve for the variable.7n = 70

• A.

N = 10

• B.

N = -10

• C.

N = 63

• D.

N = -63

A. N = 10
Explanation
To solve the equation 7n = 70, we need to isolate the variable n. We can do this by dividing both sides of the equation by 7. This gives us n = 10.

Rate this question:

• 9.

### Are 8/9 and 24/27 equivalent?

• A.

Yes

• B.

No

A. Yes
Explanation
Two fractions are equivalent if they represent the same value. To determine if 8/9 and 24/27 are equivalent, we can simplify both fractions. The numerator and denominator of both fractions are divisible by 3, so we can simplify 8/9 to 8/9 and 24/27 to 8/9. Since both fractions simplify to the same value, 8/9 and 24/27 are indeed equivalent.

Rate this question:

• 10.

### Write 3/5 as a decimal.

• A.

1.2

• B.

3.5

• C.

.6

• D.

.9

C. .6
Explanation
To convert a fraction to a decimal, you divide the numerator (top number) by the denominator (bottom number). In this case, 3 divided by 5 equals 0.6. Therefore, the decimal representation of 3/5 is 0.6.

Rate this question:

• 11.

### Write 3/5 as a percent.

• A.

6 %

• B.

60 %

• C.

3 %

• D.

30%

B. 60 %
Explanation
To write a fraction as a percent, you need to divide the numerator (3) by the denominator (5) and then multiply the result by 100. In this case, 3 divided by 5 is 0.6. Multiplying 0.6 by 100 gives us 60, so the fraction 3/5 can be written as 60%.

Rate this question:

• 12.

### Write 1.5 as a percent.

• A.

150%

• B.

15%

• C.

.15%

• D.

.015%

A. 150%
Explanation
To convert a decimal to a percent, we multiply it by 100. In this case, 1.5 multiplied by 100 equals 150. Therefore, 1.5 can be expressed as 150%.

Rate this question:

• 13.

### Write 4% as a decimal.

• A.

4.0

• B.

.4

• C.

.04

• D.

.004

C. .04
Explanation
To write a percentage as a decimal, we divide it by 100. In this case, 4% divided by 100 equals 0.04. Therefore, the correct answer is .04 as a decimal.

Rate this question:

• 14.

### Which fraction is equivalent to 12/48?

• A.

4/4

• B.

3/9

• C.

1/3

• D.

24/96

D. 24/96
Explanation
The fraction 12/48 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 12. When we divide 12/48 by 12, we get 1/4. Therefore, the fraction 12/48 is equivalent to 1/4. The answer 24/96 is not equivalent to 12/48 because it has not been simplified.

Rate this question:

• 15.

### Solve.45 - (4x3) + 10

• A.

43

• B.

23

• C.

63

• D.

33

A. 43
Explanation
The given expression is solved by following the order of operations (PEMDAS/BODMAS). First, we perform the multiplication: 4 multiplied by 3 equals 12. Then, we subtract 12 from 45, which gives us 33. Finally, we add 10 to 33, resulting in 43.

Rate this question:

### Solve  7n - 9 if n = 5

• A.

26

• B.

66

• C.

-3

• D.

44

A. 26
Explanation
By substituting n = 5 into the expression 7n - 9, we get 7(5) - 9 = 35 - 9 = 26. Therefore, the correct answer is 26.

Rate this question:

• 17.

### What is the simplest form of 14/70?

• A.

2/2

• B.

2/10

• C.

1/5

• D.

7/35

C. 1/5
Explanation
The simplest form of a fraction is when the numerator and denominator have no common factors other than 1. In this case, the numerator 14 and the denominator 70 can both be divided by 14, resulting in the fraction 1/5.

Rate this question:

• 18.

### -32 = 8n

• A.

N = 4

• B.

N = 3

• C.

N = -4

• D.

N= -3

C. N = -4
Explanation
To solve the equation -32 = 8n, we need to isolate the variable n. We can do this by dividing both sides of the equation by 8. When we divide -32 by 8, we get -4. Therefore, the value of n that satisfies the equation is -4.

Rate this question:

• 19.

### -56/-2

• A.

23

• B.

-23

• C.

28

• D.

-28

C. 28
Explanation
The given expression -56/-2 can be simplified by dividing -56 by -2, which gives us a result of 28. Therefore, the correct answer is 28.

Rate this question:

• 20.

### 13 is what percent of 52?

• A.

13%

• B.

50%

• C.

40%

• D.

25%

D. 25%
Explanation
To find the percentage, we need to divide the given number (13) by the total number (52) and multiply the result by 100. In this case, 13 divided by 52 equals 0.25. Multiplying 0.25 by 100 gives us 25%. Therefore, 13 is 25% of 52.

Rate this question:

• 21.

### A pair of jeans cost \$48. They are on sale for 30% off. How much is the sale price?

• A.

\$16.00

• B.

\$32.00

• C.

\$18.00

• D.

\$36.00

B. \$32.00
Explanation
The sale price of the jeans can be found by subtracting 30% of the original price from the original price. In this case, 30% of \$48 is \$14.40. Subtracting \$14.40 from \$48 gives us \$33.60. Therefore, the sale price is \$33.60, which is closest to \$32.00.

Rate this question:

• 22.

### Change 13/6 to a mixed number.

• A.

1 3/6

• B.

2 1/3

• C.

2 1/6

• D.

6 1/6

C. 2 1/6
Explanation
To change 13/6 to a mixed number, we divide the numerator (13) by the denominator (6). The quotient is 2 and the remainder is 1. Therefore, the mixed number representation is 2 1/6.

Rate this question:

• 23.

### Change 4 2/5 to an improper fraction.

• A.

20/5

• B.

22/5

• C.

4/25

• D.

25/5

B. 22/5
Explanation
To change a mixed number to an improper fraction, we multiply the whole number by the denominator and add the numerator. In this case, we multiply 4 by 5 and add 2 to get 22. The denominator remains the same, which is 5. Therefore, 4 2/5 can be written as the improper fraction 22/5.

Rate this question:

• 24.

### Which expression best represents this situation if x represents the number of students?If each student pays \$5.00 for the fieldtrip, how much will be paid altogether?

• A.

5 + x

• B.

5/x

• C.

5x

• D.

5 - x

C. 5x
Explanation
The expression 5x best represents the situation because it represents each student paying \$5.00 (5) and there being x number of students (x). By multiplying 5 and x, we can calculate the total amount that will be paid altogether.
