solve the literal equation for h and y

Question

628=π10^2h

2x+5y=3y+8

i can't figure this out because it confuses me. Can you help me? I have to have at least 30 characters to submit this question so im just typing alot of stuff.

Answer 1

1) pi and 10^2 are just numbers so divide both sides of the equation by (!10)^2 pi to solve for h

h = 628/100pi=

2) 2x +5y=3y +8. Subtract 3y and 2x from both sides

2y = -2x +8.

y = -x +4

Answer 2

π(10)²h = 628

For the area of a circle, you will solve for h. Divide both sides by π and 10².

h = 628/π(10)² = 628/100π = 6.28/π or approximately 2.

2x + 5y = 3y + 8

Subtract 3y on both sides → 2x + 2y = 8

Subtract 2x on both sides → 2y = 8 - 2x

Divide both sides by 2 → y = (8 - 2x)/2
