1- Choice D is correct

The correct answer is:
E = 6 \ + \ A
A = S \ – \ 4

2- Choice A is correct

The correct answer is 36^\circ
The sum of supplement angles is 180.
Let x be that angle.
Therefore, x \ + \ 4 \ x = 180
5 \ x = 180, divide both sides by 5: \ x = 36

3- Choice C is correct

The correct answer is 47
Let x be the integer. Then:
2 \ x \ – \ 3 = 91
Add 5 both sides: 2x = 94
Divide both sides by 2: \ x = 47

4- Choice A is correct

The correct answer is $120 profit
Plug in the value of x=30 into both equations. Then:
𝐶(x)=x^2 \ - \ 4 \ x=(30)^2 \ - 4 \ (30)=900 \ - \ 120=780
𝑅(x)=30 \ x=30 \ × \ 30=900
900 \ − \ 780=120

5- Choice A is correct

The correct answer is 3
Subtract \frac{1}{4 \ b} and \frac{1}{𝑏^2} from both sides of the equation. Then:
\frac{1}{4 \ b^2} \ + \ \frac{1}{4 \ b} = \frac{1}{b^2}→\frac{1}{4 \ b^2} \ − \ \frac{1}{b^2}=− \ \frac{1}{4 \ 𝑏}
Multiply both numerator and denominator of the fraction \frac{1}{b^2} by 4. Then:
\frac{1}{4 \ b^2} \ − \ \frac{4}{4 \ b^2}=− \ \frac{1}{4 \ b}
Simplify the first side of the equation: − \ \frac{3}{4 \ b^2 }=− \ \frac{1}{4 \ b}
Use cross multiplication method: 12 \ 𝑏=4 \ 𝑏^2→12=4 \ 𝑏→𝑏=3

6- Choice B is correct

The correct answer is 108 \ x^8 \ y^6
Simplify.
4 \ x^2 \ y^3 \ (3 \ x^2 \ y)^3=4 \ x^2 \ y^3 \ (27 \ x^6 \ y^3) = 108 \ x^8 \ y^6

7- Choice B is correct

The correct answer is – \ 22 \ ≤ \ x \ ≤ \ 10
First, multiply both sides of inequality by 2.
Then: \frac{|6 \ + \ x|}{2} \ ≤ \ 8→|6 \ +\ x| \ ≤ \ 16
Since 6 \ + \ x can be positive or negative, then: 6 \ + \ x \ ≤ \ 16 or 6 \ + \ x \ ≥ \ − \ 16
Then: x \ ≤ \ 10 or x \ ≥ \ − \ 22

8- Choice D is correct

The correct answer is (2, 2)
Plug in each pair of numbers in the equation.
The answer should be 12.
A. (2, 1): \ \ \ 2 \ (2) \ + \ 5 \ (1) = 9 No!
B. (– \ 1, 3): \ \ \ 2 \ (–1) \ + \ 5 \ (2) = 8 No!
C. (– \ 2, 2): \ \ \ 2 \ (– \ 2) \ + \ 5 \ (2) = 6 No!
D. (2, 2): \ \ \ 2 \ (2) \ + \ 5 \ (2) = 12 Yes!

9- Choice B is correct

The correct answer is 10
x\% \ 13 = 1.3
\frac{x}{100} \ 13 = 1.3 →
x = \frac{1.3 \ × \ 100}{13} = 10

10- Choice C is correct

The correct answer is (6 \ × \ 10^2) \ + \ (7 \ × \ 10^1) \ + \ 4 
Let’s review the choices provided:
A. (6 \ × \ 10^3) \ + \ (7 \ × \ 10^2) \ + \ (4 \ × \ 10) = 6,000 \ + \ 700 \ + \ 40 = 6,740
B. (6 \ × \ 10^2) \ + \ (7 \ × \ 10^1) \ – \ 4 = 600 \ + \ 70 \ – \ 4= 666
C. (6 \ × \ 10^2) \ + \ (7 \ × \ 10^1) \ + \ 4 = 600 \ + \ 70 \ + \ 4 = 674
D. (6 \ × \ 10^1) \ + \ (7 \ × \ 10^1) \ + \ 4 = 60 \ + \ 70 \ + \ 4 = 134
Only choice C equals to 674.

11- Choice A is correct

The correct answer is 4 cm^2
First draw an isosceles triangle.
Remember that two sides of the triangle are equal.
Let put a for the legs. Then:
𝑎=4⇒ area of the triangle is =\frac{1}{2} \ (4 \ × \ 4)=\frac{16}{2}=4 cm^2

12- Choice C is correct

The correct answer is 13 cm
Use Pythagorean Theorem: a^2 \ + \ b^2 = c^2
5^2 \ + \ 12^2 = c^2 ⇒
25 \ + \ 144 = c^2 ⇒
c^2 = 169 ⇒ c=13

13- Choice D is correct

The correct answer is 37.68
C = 2 \ π \ r
C = 2 \ π \ × \ 6 = 12 \ π
π = 3.14 → C = 12 \ π = 37.68

14- Choice C is correct

The correct answer is $27.5
\frac{5}{200} = \frac{x}{1,100}
x = \frac{5 \ × \ 1,100}{200} =27.5

15- Choice B is correct

The correct answer is 1610 minutes
23 hours = 82,800 seconds
1610 minutes = 96,600 seconds
1 days = 24 hours = 86,400 seconds
3,900 seconds

15- Choice B is correct

The correct answer is 1610 minutes
23 hours = 82,800 seconds
1610 minutes = 96,600 seconds
1 days = 24 hours = 86,400 seconds
3,900 seconds

17- Choice C is correct

The correct answer is 2,841
85.23 \ ÷ \ 0.03 =2,841

18- Choice D is correct

The correct answer is 666 Miles
To find total number of miles driven by Ed that week, you only need to subtract 46,687 from 47,353.
47,353 \ − \ 46,687=666

19- Choice A is correct

The correct answer is 69\%
Area of a circle equals: 𝐴=\pi \ r^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 1.3 \ r.
Then, the area of larger circle is: 𝐴=\pi \ r^2=\pi \ (1.3 \ 𝑟)^2=\pi \ (1.69 \ 𝑟^2)=1.69 \ 𝜋 \ r^2
1.69 \ \pi \ r^2 is 69\% bigger than \pi \ r^2.

20- Choice A is correct

The correct answer is 32 cm^2
First draw an isosceles triangle.
Remember that two sides of the triangle are equal.
Let put 𝑎 for the legs. Then:
𝑎=5⇒ area of the triangle is =\frac{1}{2} \ (8 \ × \ 8)=\frac{64}{2}=32 cm^2

21- Choice D is correct

The correct answer is 96
x \ + \ y = 24
Then: 4 \ x \ + \ 4 \ y = 24 \ × \ 4 = 96

22- Choice A is correct

The correct answer is 104
The area of the non-shaded region is equal to the area of the bigger rectangle subtracted by the area of smaller rectangle.
Area of the bigger rectangle = 12 \ × \ 10 = 120
Area of the smaller rectangle = 8 \ × \ 2 = 16
Area of the non-shaded region = 120 \ – \ 16 = 104

23- Choice A is correct

The correct answer is \frac{16}{x^3}
\frac{x^3}{16} ⇒ reciprocal is : \frac{16}{x^3}

24- Choice A is correct

4 \ \frac{1}{2} - 5 \frac{3}{4}=
4 \ \frac{2}{4} \ - \ 5 \frac{3}{4} =
\frac{18}{4} \ - \ \frac{23}{4} =
\frac{- \ 5}{4} =- \ \frac{ 5}{4}

x^2 \ – \ 6 \ x \ + \ 8 ⇒ (x \ – \ 2) \ (x \ – \ 4)

30- Choice C is correct

The correct answer is (6, 1)
\begin{cases}- \ 2 \ x \ - \ 3 \ y =\ - \ 15\\4 \ x\ + \ y= 25\end{cases}⇒ Multiplication (3) in first equation
⇒\begin{cases}- \ 2 \ x \ - \ 3 \ y =\ - \ 15\\12 \ x\ + \ 3 y= 75\end{cases}
Add two equations together ⇒ 10 \ x =60 ⇒ x=6 then; y=1

The correct answer is 2 ft.
Write a proportion and solve for the missing number.
\frac{24}{8} =\frac{ 6}{x}→ 24 \ x=6 \ × \ 8=48
24 \ x=48→x=\frac{48}{24}=2

40- Choice D is correct

The correct answer is 12.6 square feet
A = b \ h
A = 3 \ × \ 4.2 = 12.6

41- Choice A is correct

The correct answer is \ \begin{bmatrix}2 & 0\\0 & - \ 2\\- \ 3 & 3 \end{bmatrix}
\begin{bmatrix}2 & 6 \\- \ 1 & - \ 2\\- \ 5 & - \ 4 \end{bmatrix} \ + \ \begin{bmatrix}0 & - \ 6 \\1 & 0\\2 & 7 \end{bmatrix} = \ \begin{bmatrix}2 & 0\\0 & - \ 2\\- \ 3 & 3 \end{bmatrix}

42- Choice B is correct

The correct answer is 8
7∎13=\sqrt{7^2 \ + \ 15}=\sqrt{49 \ + \ 15} =\sqrt{64} = 8

43- Choice D is correct

The correct answer is (150) \ (0.85) \ (0.70)
To find the discount, multiply the number by (100\% \ – rate of discount).
Therefore, for the first discount we get: (150) \ (100\% \ – \ 15\%) = (150) \ (0.85)
For the next 15\% discount: (150) \ (0.85) \ (0.70)

44- Choice A is correct

The correct answer is 69.11 kg
Average =\frac{ sum \ of \ terms}{ number \ of \ terms}
The sum of the weight of all girls is: 21 \ × \ 65 = 1,365 kg
The sum of the weight of all boys is: 30 \ × \ 72 = 2,160 kg
The sum of the weight of all students is: 1,365 \ + \ 2,160 = 3,525 kg
Average = \frac{3,525 }{51} = 69.11

45- Choice D is correct

The correct answer is 480 Liters
Let x be the capacity of one tank. Then, \frac{3}{4} \ x=320→x=320 \ × \ \frac{3}{4}=240 Liters
The amount of water in two tanks is equal to: 2 \ × \ 240=480 Liters

46- Choice C is correct

The correct answer is - \ 2 \ x^2 \ - \ 2 \ x \ + \ 12
Use FOIL (First, Out, In, Last)
(2 \ x \ + \ 6) \ (- \ x \ + \ 2) = - \ 2 \ x^2 \ + 4 \ x \ - \ 6 \ x \ + \ 12 =- \ 2 \ x^2 \ - \ 2 \ x \ + \ 12

47- Choice D is correct

The correct answer is 65 \ π
To find the area of the shaded region subtract smaller circle from bigger circle.
S_{bigger} \ – \ S_{smaller} = π \ (r_{bigger} )^2 \ – \ π \ (r_{smaller} )^2 ⇒ S_{bigger} \ – \ S_{smaller }= π \ (9)^2 \ – \ π \ (4)^2
⇒ 81 \ π \ – \ 16 \ π = 65 \ π
