The value of y varies directly with c. If x = 2, then y = 7. Find the value of x if y = 84.
2 answers:
We are given that y varies directly with c.
We need a constant of proportionality. I decided to let c be the constant of proportionality.
y = cx
7 = 2c
7/2 = c
We are now given the value of y to be 84 and must find x.
y = cx
84 = (7/2)x
84 ÷ (7/2) = x
24 = x
Answer:
x=24
Step-by-step explanation:
y = x*c
x=2, y=7
2*c=7 => c=7/2
x*7/2 = 84
x = 84*2/7
x = 12*2
x = 24
