Answer:

Use distributive property

Divide both sides by (-2)

Step-by-step explanation:

First method: Use distributive property:

-2(n + 3) = 13

-2n - 6 = 13    

      -2n = 13 + 6

      -2n = 19

         n = 19/-2

        n = -9.5

2) Divide both sides by (-2)

-2(n +33) = 13

\frac{-2(n + 3)}{2}=\frac{13}{-2}\\\\n + 3 = -6.5\\      n = -6.5 - 3\\      n = -9.5

Arturiano [62]

Answer:

V=33.51in^3

Step-by-step explanation:

5inch-1 in

=4inch

divide by 2 because the problem gives diameter, not radius. (radius is half of diameter)

The space inside is a sphere so it will be

V=4/3πr^3

V=4/3*pi*(2)^3

V=33.51 inch cubed
