First problem:

n/4 + 2 = -9

-2 -2

n/4 = -11

x4 x4

n = -44

Check:

-44/4 + 2 = -9

-11 + 2 = -9

-9 = -9

Second problem:

3/4x = -12

0.75x = -12

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

0.75 0.75

x = -16

3/4 * (-16) = -12 OR 0.75 * (-16) = -12

-12 = -12

Still get the same answer.

Select the correct answer.

Using scientific notation, the correct statement is given by:

C. Corporation C owns the most land. Corporation A owns 8 times more land than corporation B.

<h3>What is scientific notation?</h3>

A number in scientific notation is given by:

$a \times 10^b$

With the base being $a \in [1, 10)$ .

Considering the amounts in scientific notation, the standard amounts in acres of each corporation are given as follows:

Corporation A: $3.2 \times 10^5 = 320000 = 320,000$ .

Corporation B: $4 \times 10^4 = 40000 = 40,000$ .

Corporation C: $4.3 \times 10^5 = 430000 = 430,000$ .

Hence corporation C owns the most land. 320,000/40,000 = 8, hence Corporation A owns 8 times more land than corporation B, and statement C is correct.
