84- Solve the following equation?
6^x=1,296
(A) 4
(B) 10
(C) 12
(D) 7
1- Choice A is correct

The correct answer is - \ \frac{9}{5}
\frac{- \ 45 \ × \ 0.2}{5}=\frac{- \ 45 \ × \ \frac{2}{10}}{5}\Rightarrow
\frac{\frac{- \ 45 \ × \ 2 }{10}}{5} = \frac{- \ 90}{50}\Rightarrow
- \ \frac{9}{5}

2- Choice A is correct

The correct answer is $250
10\% off equals $25.
Let x be the original price of the table.
Then: 10\% of x=25→0.10 \ x=25→x=\frac{25}{0.10}=250

3- Choice C is correct

The correct answer is 14 \ π
Use the formula of areas of circles.
Area of circle = \pi \ r^2 ⇒ 49 \ 𝜋 = 𝑟^2 ⇒ 49 = 𝑟^2 ⇒ 𝑟 = 7
Radius of the circle is 7.
Now, use the circumference formula:
Circumference = 2\ π \ r = 2 \ π (7) = 14 \ π

4- Choice B is correct

The correct answer is 3
Method 1:  9=3^2→9^x=(3^2)^x=3^{2 \ x}
729=3^6→3^{2 \ x}=3^6→2 \ x=6→x=3
Method 2: 9 \ x=729
Let’s review the choices provided:
A. 2 \ \ \ 9^x=729→9^2=81
B. 3 \ \ \ 9^x=729→9^3=729
C. 4 \ \ \ 9^x=729→9^4=6,561
D. 5 \ \ \ 9^x=729→9^5=59,049

5- Choice A is correct

The correct answer is 25\%
Use the formula for Percent of Change:\frac{ New \ Value \ − \ Old Value}{old \ value} \ × \ 100\%
\frac{30 \ − \ 40}{40} \ × \ 100\% = \ – \ 25\% (negative sign here means that the new price is less than old price)

6- Choice B is correct

The correct answer is \frac{1}{8}, \frac{3}{8}, \frac{2}{5}, \frac{1}{2}
\frac{1}{8}=0.125
\frac{1}{2}=0.5
\frac{2}{5}=0.4
\frac{3}{8}=0.375

7- Choice C is correct

The correct answer is 10
If the score of Mia was 40, therefore the score of Ava is 20.
Since, the score of Emma was half as that of Ava, therefore, the score of Emma is 10.

8- Choice C is correct

The correct amswer is 5 \ x \ - \ 10 \ y
2 \ 𝑓=2 \ × \ (2 \ x \ - \ 6 \ y)=4 \ x \ − \ 12 \ y
2 \ 𝑓 \ + \ 𝑔=4 \ x \ − \ 12 \ y \ + \ x \ + \ 2 \ y
2 \ 𝑓 \ + \ 𝑔=5 \ x \ - \ 10 \ y

9- Choice C is correct

The correct answer is 712,232.691
712,232,691 \ × \ 0.001 =712,232,691\ × \frac{1}{1000}=712,232.691

10- Choice A is correct

The correct answer is 16
Let x be the number.
Write the equation and solve for x.
\frac{1}{3 } \ × \ 12=\frac{1}{4} \times x ⇒
\frac{1 \ × \ 12}{3}= \frac{1 \ x}{4} , use cross multiplication to solve for x.
4 \ × \ 12=3 \ x \ × \ 1 ⇒48=3 \ x ⇒ x=16

11- Choice B is correct

The correct answer is 51.5
Mean = \frac{7 \ + \ 15 \ + \ 26 \ + \ 32 \ + \ 48 \ + \ 63 \ + \ 100 \ + \ 121}{8}=\frac{412}{8}=51.5

12- Choice A is correct

The correct answer is 7.40
1.18=\frac{118}{100} and 6.3=\frac{63}{10}
