Question

P is directly proportional to Q when P is 22, Q is 4. Find the equation connecting P and Q

Hence find :
P when Q=7

Answer 1

Hint:
start with the relation P=kQ
where k is a constant to be found using the fact that P=22 when Q=k.

Answer 2

You mean when P=22 and Q=4

Answer 3

22 = 4 k
How much is k?

Answer 4

Are you with me?

Answer 5

@SugarMochi
@eliesaab is helping you, please respond.

@eliesaab yes, I meant Q=4, that makes 22=4k as you had it.

Answer 6

Im-- yeah im following somehow

Answer 7

Can you solve 22=4 k for k?

Answer 8

\[
k=\frac{22}4=\frac {11}2\]

Answer 9

\[
P= \frac {11}2 Q =\frac {11}2 7=\frac {77}2=38.5
\]

Answer 10

@eliesaab: If you're going to ask someone, "can you solve so and so for k," give the other person time to do it. Why were you doing someone else's assignment?

Answer 11

Your job is to enable the other person to find his or her own answer, that is, to do his or her own work.
