## Answers:

1- **C**

Let \(x\) be the number. Write the equation and solve for \(x\).

\((24 – x) ÷ x = 3\)

Multiply both sides by \(x\).

\((24 – x) = 3x\), then add \(x\) both sides. \(24 = 4x\), now divide both sides by \(4\).

\(x = 6\)

2- **B**

The sum of supplement angles is \(180\). Let \(x\) be that angle. Therefore, \(x + 5x = 180\)

\(6x = 180\), divide both sides by \(6: x = 30\)

3- **C**

The average speed of john is: \(150 ÷ 6 = 25\)

The average speed of Alice is: \(180 ÷ 4 = 45\)

Write the ratio and simplify.

\(25 : 45 ⇒ 5 : 9\)

4- **A**

The percent of girls playing tennis is: \(40 \% × 25 \% = 0.40 × 0.25 = 0.10 = 10 \%\)

5- **E**

Solving Systems of Equations by Elimination

\(3x-4y= -20\)

\(-x+2y=10\)

Multiply the second equation by \(3\), then add it to the first equation.

\(3x-4y= -20\)

\(3(-x+2y=10)\)

\(\Downarrow\)

\(3x-4y= -20\)

\(-3x+6y=30\)

\(\Downarrow\)

\( 2y= 10\)

\(\Downarrow\)

\(y= 5\)

6- **C**

Add the first \(5\) numbers. \(40 + 45 + 50 + 35 + 55 = 225\)

To find the distance traveled in the next \(5\) hours, multiply the average by number of hours.

Distance = Average \(×\) Rate \(= 50 × 5 = 250\)

Add both numbers. \(250 + 225 = 475\)

7- **C**

Use distance formula:

Distance = Rate \(×\) time \(⇒ 420 = 50 ×\) T, divide both sides by \(50\). \(420 \div 50 = T ⇒ T = 8.4\) hours.

Change hours to minutes for the decimal part. \(0.4\) hours \(= 0.4 × 60 = 24 \) minutes.

8- **D**

Smallest \(4\)–digit number is \(1000\), and biggest \(4\)–digit number is \(9999\). The difference is: \(8999\).

9- **E**

\(6^4 = 6 × 6 × 6 × 6 = 1296\)

10- **D**

Use Pythagorean Theorem: \(a^2 + b^2 = c^2\)

\(6^2 + 8^2 = c^2 ⇒ 100 = c^2 ⇒ c = 10\)
