Explain how to model the problem with algebra tiles and then write an algebraic expression that represents the situation. Daniel worked three times as many hours.

The variable, the number of hours Daniel worked, is modeled by an orange x tile. Working 3 times as many hours is modeled with 3 orange x tiles. The multiplication expression that represents the situation is 3x.

y = 3*x

Explanation:

There are two variables.

x - The number of hours of someone.

y - The number of hours that Daniel worked.

The algebraic expression is:

y = 3*x
