If x varies directly with y and x = 2.5 when y = 10, find x when y = 16.

x = 4

Step-by-step explanation:

If x varies directly with y

Directly Proportional:

where, k is constant of proportionality

x = 2.5 when y = 10

Equation:

y=4x

Put y=16 and solve for x

Hence, The value of x is 4 at y=16

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

your answer is 125y5
