Sample MathPower 8 Questions and Their Answer Keys

Question 1: Simplify the expression 3(2x + 4) - 5x

Solution:

1. Distribute 3 inside the parentheses:

3 2x + 3 4 = 6x + 12

2. Subtract 5x:

6x + 12 - 5x = (6x - 5x) + 12 = x + 12

Answer: x + 12

Question 2: Find the area of a triangle with a base of 10 cm and a height of 6 cm.

Solution:

Use the area formula for a triangle:

Area = (1/2) base height

= (1/2) 10 6

= 5 6 = 30 cm²

Answer: 30 cm²

Question 3: Solve for x: 2x - 7 = 13

Solution:

1. Add 7 to both sides:

2x = 13 + 7 = 20

2. Divide both sides by 2:

x = 20 / 2 = 10

Answer: x = 10

Question 4: If the ratio of cats to dogs is 3:4 and there are 12 cats, how many dogs are there?

Solution:

Set up the proportion:

3 / 4 = 12 / d

Cross-multiplied:

3d = 4 12 = 48

Divide both sides by 3:

d = 48 / 3 = 16

Answer: 16 dogs

Question 5: A circle has a radius of 7 cm. Find its circumference.

Solution:

Circumference = 2πr

= 2 3.14 7 ≈ 43.96 cm

Answer: approximately 43.96 cm
