Question

If Q is directly proportional to p and Q =28 when p=4. (1) express Q in terms of p, (2) find the value of Q when p=5, (3) calculate the value of p when Q=42​

Answer 1

Answer:

Step-by-step explanation:

Q is directly proportional to P

Therefore Q/P= constant

i) P=5, Q=?

28/4=Q/5

(28*5)/4=Q

35=Q

if P=5, Q=35

ii)P=?, Q=42

28/4=42/P

P=(42*4)/28

P=6
