T = 30h + 84l
C = h + 2l
P = h + 4l
C = 18h + 36l
P = 12h + 48l
Answer:
-18 feet
Step-by-step explanation:
18-32-4
18-36= -18
The answer to the problem is 5
Given that y varies directly with x and inversely with z, then:
a] Equation that models the relationship
y=kx/z
where k is the constant of proportionality, given by:
k=yz/x
k=(28×8)/32
k=7
The equation that models the relationship is:
y=7x/z
b]
<span>find y when x = 12 and z = 3
The value of y will be given:
y=(7</span>×12)/3
<span>y=28
