4x = -2y Solve for y
I am confused about how to solve this. Can somebody please help step by step?

Your answer is y = -2x

Step-by-step explanation:

-2y = 4x     Divide both sides by -2

(-2 / -2) y = 4x/-2    Simplify

y = -2x

Step-by-step explanation:

The answer does not mean that you will have a pure number. Divide by -2

4x/-2 = y     Combine

-2x = y      That's all you can do. You are finished.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
