6. Suppose that y varies inversely with x. Write an equation for the inverse variation, y = 4 when x-7

If y varies inversely as x, then we write it as:

y = k/x

where k is some constant.

If we multiply both sides of this equation by x we get an equation for k:

k = x*y

We are given that y=4 when x=7, therefore:

k = 7*4 = 28

Put this back into our original equation to get:

y = 28/x

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
