Question

if Q varies directly as P and Q = 28 when P = 4, then
(a) write an equation connecting P and Q;
(b) find the value of Q when P = 5; and
(c) find the value of P when Q = 42.​

Answer 1

Step-by-step explanation:

( a) 7P=Q

7*4=28

28=28

b) 7P = Q

7*5 = 35

c) 7P = Q

7P = 42

P = 42/7

= 6
