Answer:

The answer to your question is below

Step-by-step explanation:

First way

20 = 5(-3 + x) expand

20 = -15 + 5x simplify like terms

5x = 20 + 15

5x = 35 divide both sides by 5

5x/5 = 35/5

x = 7

Second way

20/5 = 5/5 (-3 + x) Divide both sides by 5

4 = -3 + x Add +3 in both sides

4 + 3 = -3 + 3 + x Simplify like terms

7 = x

What's the distance between (0,2) and (0,8)?

N76 [4]

Answer:

6 units

Step-by-step explanation:

The distance between two points can be calculated with the formula

$\boxed{\textcolor{steelblue}{\text{Distance between 2 points}= \sqrt{(y_1 - y_2)^{2} + (x_1 - x_2)^{2} } }}$

However, since (0, 2) and (0, 8) have the same x coordinate of 0, the distance between them is the difference in their y-coordinates.

Distance between (0, 2) and (0, 8)

= 8 -2

= 6 units
