2x + 5y + 30 = 0 the point ( 5/2 , y) is a solution to the equation shown. what is the value of y? a) -7 b) -5 c) 0 d) 5

A)-7

Step-by-step explanation:

2x + 5y + 30 = 0

Let x = 5/2

Substitute into the equation

2(5/2) +5y +30 =0

5+5y+30=0

Combine like terms

35 +5y =0

Subtract 35 from each side

35-35 +5y = -35

5y=-35

Divide by 5

5y/5=-35/5

y = -7

no not all of them.

step-by-step explanation:

some of them have a square base.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
