Solve each equation for the indicated variable. (ACTUAL ANSWERS PLEASE)

Step-by-step explanation:

a)

A= 1/2 h(b1 + b2)

2A= h(b1+b2)

h= 2A/(b1+b2)

b)

I=P(1+rt)

I/P = 1+rt

I/P -1 = rt

t = (I/P -1) / r

c)

y = 5/x + a

y- a = 5/x

x(y-a) = (5/ x) × x

x = 5/ y- a

2nd one in the first row is correct
