Hey there! :)

Answer:

A. x = 5.

Step-by-step explanation:

Starting with:

4x + 1 = 21

Subtract 1 from both sides:

4x + 1 - 1 = 21 - 1

4x = 20

Divide both sides by 4:

4x/4 = 20/4

x = 5.

QveST [7]

Answer:

Rate: In mathematics, a rate is the ratio between two related quantities in different units. If the denominator of the ratio is expressed as a single unit of one of these quantities. "The most common type of rate is "per unit of time."

Unit Rate: A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.
