Answer:

Kevin is 16; Timothy is 10

Step-by-step explanation:

k= Kevin's age

t=Tim's age

k=t+6

k-4=2(t-4)

k-4=2t+8

(t+6)-4=2t-8 :substitution

t+2=2t-8

t=10

k=t+6

k=10+6

k=16

When y is 4, p is 0. 5, and m is 2, x is 2. If x varies directly with the product of p and m and inversely with y, which equatio

Answer:

$\dfrac{xy}{pm}=8$

Step-by-step explanation:

If x varies directly as the product of p and m, and inversely with y, the relation can be written ...

x = k(pm)/y . . . . where k is the constant of proportionality

This can be solved for k:

k = xy/pm

For the given values, the value of k is ...

k = (2)(4)/((0.5)(2)) = 8

Then the relation between the variables can be written ...

(xy)/(pm) = 8
