A) 5x = 0.4 — 3) Multiple by 1/5

B) x/5 = 8 — 1) Multiple by 5

C) 3 = -x/5 — 2) Multiple by -5

D) 7 = -5x — 4) Multiple by -1/5

Explanation:

A:
5x = 0.4

5x • 1/5 = 0.4 • 1/5

x = 2/25 or 0.08

B:
x/5 = 8

x/5 • 5 = 8 • 5

x = 40

C:
3 = -x/5

3 • -5 = -x/5 • -5

-15 = x

x = -15

D:
7 = -5x

7 • -1/5 = -5x • -1/5

-7/5 = x

x = -7/5 or -1.4

Hope it helps!

How to determine the maximum and minimum lengths of a missing side on a triangle?

Well to find the missing side you're going to need the other two. Take the one side and multiply by itself. Take the other one and multiply by itself. Add those two products. Then root it. Basically find something that multiplys by itself to get that product

<h2><u>ABSOLUTE VALUE</u></h2>

The absolute value of a number is the distance from 0 to that number. The distance is positive, hence, the absolute value is always a positive number.
