C = 2 pi r

R is radius and it’s half of diameter
Pi is always a constant = 3.14

Diameter = D = 2r

We substitute the 2r with D

C = D pi = 28*3.14

Circumference = 87.9 cm (don’t forget your units)

Simplify 5x + 2(x - 3) = -2(x - 1)
Kruka [31]

Answer:

x=8/9

Step-by-step explanation:

5x+2(x-3)=-2(x-1)

1) Distribute 2 to x and -3:

5x+2x-6=-2(x-1)

2) Distribute -2 to x and -1:

5x+2x-6=-2x+2

3) Combine alike terms:

7x-6=-2x+2

4) Add 2x to both sides:

9x-6=2

5) Add 6 to both sides:

9x=8

6) Divide both sides by 9:

x=8/9
