The value of y is directly proportional to the value of x. If y = 35 when x = 140, what is the value of y when x = 70?
antiseptic1488 [7]

Answer:

y = 17.5

Step-by-step explanation:

Use the direct proportion equation, y = kx

Plug in the x and y values to solve for k

y = kx

35 = k(140)

0.25 = k

Then, plug in the k value and given x value into the equation, and solve for y

y = kx

y = 0.25(70)

y = 17.5
