Why must you perform the same operation on both sides of the equation when isolating the variable

You must perform the same operation on both sides of the equation when isolating the variable in order to keep the equation balanced.

Step-by-step explanation:

According to the properties of equality, you must perform the same exact operation to each side of the equation, so you must also subtract from to keep the equation balanced.

step-by-step explanation:

f

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'.
