Question

Anyone that can answer it right gets 30!

Answer 1

Answer:

First

Step-by-step explanation:

1.

$\frac{48}{8} + 2^{3} = 6 + 8 = 14$

$5 + 3^2 = 5 + 9 = 14$

2.

$9^{2} - 7^{2} = 81 - 63 = 18$

$\frac{20}{7-2} = \frac{20}{5} = 4$

3.

$\frac{150}{5^2} = \frac{150}{25} = 6$

$30 - 4^{2} - 12 = 30 - 16 - 12 = 30 - 28 = 2$

4.

$\frac{8 - 7}{2} - 12 = 0.5 - 12 = -11.5$

$22 - 2 * 3 = 22 - 6 = 16$

Answer 2

Answer:

first and fourth

Step-by-step explanation:

Equate and compare both sides of the equations. If both sides are equal then the equation is true.

48 ÷ 8 + 2³ = 6 + 8 = 14

right side = 5 + 3² = 5 + 9 = 14

This is a true equation

---------------------------------------

9² - 7² = 81 - 49 = 32

right side = 20 ÷ (7 - 2) = 20 ÷ 5 = 4

This is not a true equation

---------------------------------------

$\frac{150}{5^2}$ = $\frac{150}{25}$ = 6

right side = 30 - 4² - 12 = 30 - 16 - 12 = 14 - 12 = 2

This is not a true equation

--------------------------------------------------

$\frac{8(7)}{2}$ - 12 = $\frac{56}{2}$ - 12 = 28 - 12 = 16

right side = 22 - 2 × 3 = 22 - 6 = 16

This is a true equation
