## Answers:

1- **A**

\(0.00002389 = \frac{2.389}{100000}⇒2.389 × 10^{–5}\)

2- **B**

A linear equation is a relationship between two variables, \(x\) and \(y\), and can be written in the form of \(y = mx + b\).

A non-proportional linear relationship takes on the form \(y=mx + b\), where \(b ≠ 0\) and its graph is a line that does not cross through the origin.

3-** B**

Translated 5 units down and 4 units to the left means: \((x.y) ⇒ (x-4,y-5)\)

4- **D**

Write the proportion and solve for the missing side.

\(\frac{Smaller \space triangle \space height}{Smaller \space triangle \space base}=\frac{Bigger \space triangle \space height}{Bigger \space triangle \space base} ⇒\frac{90 \space cm}{160 \space cm}=\frac{90 + 360 \space cm}{x} ⇒ x = 800 \space\) cm

5- **B**

\(\frac{3}{22} = 0.136 \)and \(19\% = 0.19\) therefore \(x\) should be between 0.136 and 0.19

Choice B. \(5/36 = 0.138\) is between 0.136 and 0.19

6- **A**

The ratio of boys to girls is 2:3. Therefore, there are 2 boys out of 5 students. To find the answer, first divide the total number of students by 5, then multiply the result by 2.

\(600 ÷ 5 = 120 ⇒ 120 × 2 = 240\)

7- **D**

If the length of the box is 27, then the width of the box is one-third of it, 9, and the height of the box is 3 (one-third of the width). The volume of the box is:

V = lwh = \((27) (9) (3) = 729\)

8- **C**

To find the total number of miles driven by Ed that week, you only need to subtract 40,907 from 41,053.

\(41,053-40,907=146\)

9- **B**

\(3(w^2 + x) = 32\)

10- **B**

\(-2x- y = -9\)

\(5x-2y= 18\)

⇒ Multiplication \((–2)\) in first equation ⇒

\(4x +2y =18\)

\(5x-2y= 18 \)

Add two equations together \(⇒ 9x =36 ⇒ x= 4\) then: \(y = 1\)

11- **A**

First, draw an isosceles triangle. Remember that two sides of the triangle are equal.

Let’s put a for the legs. Then:

\(a=6⇒\) area of the triangle is = \(\frac{1}{2}(6×6)=\frac{36}{2} = 18 \)cm\(^2\)

12- **A**

Factor each trinomial \(x^2 – 2x – 8\) and \(x^2 – 6x + 8\)

\(x^2 – 2x – 8 ⇒ (x – 4)(x + 2) \)

\(x^2 – 6x + 8 ⇒ (x – 2)(x – 4)\)

13- **B**

Subtract \(\frac{1}{6b}\) and \(\frac{1}{b^2}\) from both sides of the equation. Then:

\(\frac{1}{6b^2}+\frac{1}{6b}=\frac{1}{b^2}→\frac{1}{6b^2}-\frac{1}{b^2}=-\frac{1}{6b}\)

Multiply both the numerator and denominator of the fraction \(\frac{1}{b^2}\) by 6. Then:

\(\frac{1}{6b^2}-\frac{6}{6b^2}=-\frac{1}{6b}\)

Simplify the first side of the equation:

\(-\frac{5}{6b^2}=-\frac{1}{6b}\)

Use cross multiplication method: \( 30b=6b^2→30=6b→b=5\)

14- **B**

First, multiply both sides of the inequality by 7. Then:

\(\frac{|3+x|}{7}≤ 5→|3+x|≤35\)

Since \(3+x\) can be positive or negative, then:

\(3+x≤35\) or \(3+x≥-35\)

Then:

\(x≤32\) or \(x≥-38\)

Choice B is correct.

15- **D**

Plug in the value of \(x=30\) into both equations. Then:

\(C(x) = x^2+2x=(30)^2+2(30)=900+60=960\)

\(R(x)=40x=40×30=1,200 \)

\(1,200 – 960 = 240\)

16- **D**

\(E = 4 + A\)

\(A = S – 3\)

17- **C**

\(23\) hours \(= 82,800\) seconds

\(1520\) minutes \(= 91,200\) seconds

\(2\) days\( = 48\) hours \(= 172,800\) seconds

4200 seconds

18- **C**

Let’s review the choices provided:

A. \((5 × 103) + (2 × 102) + (3 × 10) = 5,000 + 200 + 30 = 5,230\)

B. \((5 × 102) + (2 × 101) – 5 = 500 + 20 – 5 = 515\)

C. \((5 × 102) + (2 × 101) + 3 = 500 + 20 + 3 = 523\)

D. \((5 × 101) + (2 × 102) + 3 = 50 + 20 + 3 = 73\)

Only choice C equals to 523.

19- **C**

\(\frac{4}{400}=\frac{x}{960}\)

\(x = \frac{4 × 960}{400} = 9.6\)

20- **B**

The area of a circle equals:

\(A=πr^2\)

The new diameter is \(30\%\) larger than the original then the new radius is also \(30\%\) larger than the original.

\(30\%\) larger than r is \(1.3r\).

Then, the area of the larger circle is:

\(A=πr^2=π(1.3r)^2=π(1.69r^2 )=1.69πr^2\)

\(1.69πr^2\) is \(69\%\) bigger than \(πr^2\).
