1. Correct answer: (D)

To find:
The number between

Solution:
Topic(s): Fractions

The answer between 0.2 and 0.25 is 0.21

Answer: (D) 0.21

2. Correct answer: (B)

To find:
Which of the points are nearer to the origin

Solution:
Topic(s): Coordinate geometry

Sketch the locations of the points if necessary

From the sketch, you can see that B (0, ) is nearest to the origin

Answer: (B)

3. Correct answer: (A)

Given:
The figure
AB is a line

To find:
The value of y

Solution:
Topic(s): Supplementary angles

Since AB is a line, we can use the supplementary angles rule to from two equations.

y + x + x = 180 ⇒ y + 2x = 180 (equation 1)

5x = 180 ⇒ x = 3 (equation 2)

Substituting equation 2 into equation 1
y + 2(36) = 180 ⇒ y = 108

Answer: (A) 108

4. Correct answer: (C)

Given:
6,565 = 65(x + 1)

To find:
The value of x

Solution:
Topic(s): Isolate variable

6,565 = 65(x + 1) ⇒ 65x + 65 = 6,565 ⇒ 65x = 6,500 ⇒ x = 100

Or you may be able to see from the pattern of the number 6565 that it would be 65 × 101

Answer: (C) 100

5. Correct answer: (D)

Given:
m^x • m⁷ = m²⁸

To find:
x + y

Solution:
Topic(s): Exponents

x + y = 21 + 3 = 24

Answer: (D) 24
