Which property justifies this statement if 4x=20 then x=5

We are given the equation:

4 x = 20

To get to x = 5, what was did was to divide both sides by 4. That is:

4 x / 4 = 20 / 4

x = 5

Therefore in this case, the property which justifies the statement is the Division Property of Equality. Which states if one side is divided by a number, then the other side should be also divided with the same number.

step-by-step explanation:

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'.
