13.) Solve for M<br> 14.) Solve for A<br> 17.) Solve for H
brilliants [131]

Answer:

See Below (Isolate the variables)

Step-by-step explanation:

13) d = 4AM solve for M

Divide both sides by 4A

\frac{d= 4AM}{4A}

\frac{d}{4A} = M

14) \frac{A}{6} = f+h  solve for A

Multiply both sides by 6

A = 6( f+h)

15) h - m = qb solve for H

Add m to both sides

h - m = qb

  + m   +m

h = qb + m
