A is 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

Respuesta :

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.
