Mathematics
1 answer:
alex41 [277]3 years ago
4 0

Answer:

Step-by-step explanation:

V = 1/3 pi r^2 h                Multiply both sides by 3

3V = pi r^2 h                   Divide by pi * h

\frac{3*V}{\pi * h}    = r^2                       Take the square root

\sqrt{\frac{3V}{\pi*h} }      = r

What is x in the equation -3(7-2x)+3=8x-10
damaskus [11]

Answer:

x=-4

Step-by-step explanation:

−3(7−2x)+3=8x−10

Step 1: Simplify both sides of the equation.

−3(7−2x)+3=8x−10

(−3)(7)+(−3)(−2x)+3=8x+−10(Distribute)

−21+6x+3=8x+−10

(6x)+(−21+3)=8x−10(Combine Like Terms)

6x+−18=8x−10

6x−18=8x−10

Step 2: Subtract 8x from both sides.

6x−18−8x=8x−10−8x

−2x−18=−10

Step 3: Add 18 to both sides.

−2x−18+18=−10+18

−2x=8

Step 4: Divide both sides by -2.

−2x

−2

=

8

−2

x=−4
