Answer:
y = 
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 5 when x = 6
k =
= 
y =
x ← equation of variation
When x = 5, then
y =
× 5 = 
Answer: Division
Divide both sides by 75 to isolate N
Answer:
L times height equals area. So it's (8+8)×(8+2)=160 square inches
Step-by-step explanation:
Answer:
603000
Step-by-step explanation:
f(t(w))=25000+40(14200+250)
f(t(w))=25000+40(14450)
f(t(w))=25000+578000
f(t(w))=603000
