Answer:

Equation: x-(-2)=21

Solution: x=19

Step-by-step explanation:

A number decreased by -2 is equal to 21.

Let's call the number,x. Decreased means we are going to subtract.

x-(-2)=21

-(-2) is just +2:

x+2=21

Subtract 2 on both sides:

x=21-2

Simplify:

x=19

So if 19 is decreased by -2 we should get 21.

Step-by-step explanation:

1. Find circumference with the Formula C=πd

C=3.14 x 5.6

C=17.584 or 17.6 Rounded to the nearest Tenths

2. Radius is Always half of the Diameter.

5.6/2 = 2.8

2.8 is your radius.

3. If you want to check you work try the formula C=2πr to see if things checks out.

C=2 x 3.14 x 2.8

C= 17.584 or 17.6 Rounded to the nearest Tenths
