## Best PSAT 10 Math Prep Resource for 2021

## Answers:

1- **C**

\( $9×10=$90\)

Petrol use: \(10×2=20\) liters

Petrol cost: \(20×$1=$20\)

Money earned: \($90-$20=$70\)

2- **D**

Five years ago, Amy was three times as old as Mike. Mike is 10 years now. Therefore, 5 years ago Mike was 5 years.

Five years ago, Amy was: \(A=3×5=15 \)

Now Amy is 20 years old: \(15 + 5 = 20\)

3- **D**

\(\begin{cases}\frac{-x}{2}+ \frac{y}{4} = 1 \\ \frac{-5y}{6}+2x = 4 & \end{cases}\)

Multiply the top equation by 4. then:

\(-2x+y=4\)

\(\frac{-5y}{6} + 2x = 4\)

Add two equations.

\( \frac{1}{6}y=8→y=48 \)

plug in the value of y into the first equation \(→(x=22)\)

4- **B**

Two triangles ∆BAE and ∆BCD are similar. Then:

\(\frac{AE}{CD} = \frac{AB}{BC}\)

\(\frac{4}{6} = \frac{x}{12}\)

then:

\(48-4x=6x→10x=48→x=4.8\)

5- **D**

\(2x^2-11x+8=-3x+18→2x^2-11x+3x+8-18=0→2x^2-8x-10=0\)

\(→2(x^2-4x-5)=0→\) Divide both sides by 2. Then:

\(x^2-4x-5=0\), Find the factors of the quadratic equation.

\(→(x-5)(x+1)=0→x=5\) or \( x=-1\)

\(a>b\), then: \(a=5\) and \(b=-1\)

\(\frac{a}{b} = \frac{5}{-1}= -5 \)

6- **C**

The area of the floor is: 6 cm \(×\) 24 cm = 144 cm

The number is tiles needed \(= 144 ÷ 8 = 18\)

7- **A**

\(2x+4>11x-12.5-3.5x→\) Combine like terms:

\(2x+4>7.5x-12.5$$→\) Subtract \(2x\) from both sides: \(4>5.5x-12.5\)

Add 12.5 both sides of the inequality.

\(16.5>5.5x\)

Divide both sides by 5.5.

\(\frac{16.5}{5.5}>x→x<3\)

8- **A**

\(3a=4b→b=\frac{3a}{4}\) and \( 3a=5c→c= \frac{3a}{5}\)

\(a+2b+15c=a+ (2× \frac{3a}{4})+(15× \frac{3a}{5})=a+1.5a+9a=11.5a\)

9- **C**

\(x\) is the number of all sales profit and \(2\%\) of it is:

\(2\%×x=0.02x\)

Employer’s revenue: \(0.2x+7000\)

10- **C**

First, find the factors of numerator and denominator of the expression. Then simplify.

\(\frac{5x^2+75x-80}{x^2-1}=\frac{5(x^2+15x-16)}{(x-1)(x+1)}\)

\(\frac{5(x+16)(x-1)}{ (x-1)(x+1)}=\frac{5(x+16)}{ (x+1)} \)

\(=\frac{(5x+80)}{ (x+1)}\)
