Solve the equation for a. K = 4a + 9ab

a = K(4 + 9b)
a = 4(K + 9b)
a = a equals StartFraction 4 plus 9 b Over K EndFraction equals h.
a = a equals StartFraction K Over 4 plus 9 b EndFraction equals h.

a = k/(4 + 9b)

Step-by-step explanation:

Here, we want to make a the formula subject

We have this as;

k = a(4 + 9b)

a = k/(4 + 9b)

a=K(4 + 9b)

its c or d   take a lucky guess my dude

$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
