Answer:
Y = 120
Step-by-step explanation:
Y & X
Y = K(X) where K is constant
given: 72 = K(6)
i.e K = 12
Y = 12(x) is the relationship
Y = 12(10)
Y = 120
Answer:

Step-by-step explanation:
when a=5 and b=-3 is

Solve for l.
p=2(l+w)
Flip the equation.
2l+2w=p
Add -2w to both sides.
2l+2w+−2w=p+−2w
2l=p−2w
Divide both sides by 2.
2l/2=p−2w/2
l=1/2p−w
