The value of y varies directly with x. If x = 3, then y = 4. What is the value of x when y = 120 ?
Marizza181 [45]

Answer:

x = 90

Step-by-step explanation:

If x = 3 and y = 4 then when y = 120 just find out what times 4 = 120

which is 30.

so just multiply 30 for x = 3, then the answer will be 90

x = 90
