The measurement, y, varies directly with regard to another value, x. if y = 9 and x = 24, find x for y = 25.

x=66.667

Step-by-step explanation:

Basically, if y varies directly with a value x, you get an equation of the form y=kx, where k is a constant. To answer the question, first substitute 9 into y, and 24 into x.

                                                   9=24k

                                                   k=0.375

k is 0.375, so to get x, substitute 0.375 into k and 25 into y

                                                   25=0.375x

                                                     x=66.667

And we got it!

The solution is x ≤ 1 or x ≥ 15

Step-by-step explanation:

Given the two inequalities

we have to solve the inequalities.

Subtract 3x from both sides

Adding 8 on both sides, we get

Subtracting 3 from both sides

Divide by -2

The solution is x ≤ 1 or x ≥ 15
