## 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- **A**

The sum of supplement angles is 180. Let \(x\) be that angle. Therefore, (x+9x =180,10x=180\), divide both sides by \(10: x=18\)

3- **C**

The average speed of john is: \(150÷6=25\) km, The average speed of Alice is: \(160÷4=40\) km.Write the ratio and simplify. \(25∶40 ⇒ 5:8\)

4- **C**

\($7×10=$70\), Petrol use: \(10×2=20\) liters. Petrol cost: \(20×$1=$20\)

Money earned: \($70-$20=$50\)

5- **C**

average \(=\frac{sum \ of \ terms}{number \ of \ terms}=\frac{12+ 13+7+21+22}{5} = \frac{75}{5} =15\)

6- **C**

Let x be the original price. If the price of the sofa is decreased by \(15\%\) to $476, then: \(85\%\) of \(x=476 ⇒ 0.85x=476 ⇒ x=476÷0.85=560\)

7- **D**

Use Pythagorean Theorem: \(a^2+b^2=c^2, 9^2+12^2= c^2 ⇒ 81+144=c^2⇒ 225=c^2⇒c=15\)

8- **A**

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

9- **A**

The area of the circle is less than \(12 π\). Use the formula of areas of circles. Area \(=πr^2 ⇒ \)

\(36 π> πr^2⇒ 36>r^2⇒ r<6\). The radius of the circle is less than 6. Let’s put 6 for the radius. Now, use the circumference formula: Circumference \(=2πr=2π (6)=12 π\)

Since the radius of the circle is less than 6. Then, the circumference of the circle must be less than \(12 π\). Only choice A is less than \(12 π\).

10- **C**

\(\begin{cases}x+4y=10 \\ 5x+10y=10\end{cases}\rightarrow\) Multiply the top equation by \(-5\) then,

\(\begin{cases}-5x-20y=-50 \\ 5x+10y=10\end{cases}\rightarrow\) Add two equations

\(-10y=-40→y=4\) , plug in the value of y into the first equation

\(x+4y=10→x+4(4)=10→x+16=10\)

Subtract 16 from both sides of the equation. Then: \(x+16=10→x=-6\)
