Ais directly proportional to b when a =12 and b =3
a.)find a formula for a in terms of b
b.)find the value of a when b =5
c.)find the value of b when a =36

A) To find A in terms of B, we need to find A = xB. One given is A = 12 and B = 3. We substitute, which gives us 12 = x4. Divide both sides by 4, which gives us x = 3. This means that A = 3B.

B) For this, we can just plug in 5 as B in our equation. A = 3*5 -> A = 15.

C) We can plug in A as 36. 36 = 3B -> B = 12.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

99
