Answer: 280 = x
Step-by-step explanation: Okay you are using this equation! y = kx But you must rearrange it!
When rearranged you get y/x = k
Plug in x and y!
y/x = k
35/140 = k
0.25 = k
Now find the value of x.
You use this formula now, y/k = x
Plug in k from the last problem and y = 70
y/k = x
70/0.25 = x
280 = x
