Question

Which equation can be used to help solve the equation below?

Answer 1

Step-by-step explanation

We have the equation:

`□*6=420.`

1) To solve this equation, we divide both sides by 6:

`(□*6)/6=420/6.`

2) Using the associative property for the division and simplifying, we have:

`\begin{gathered} □*(6/6)=420/6, \\ □*1=420/6, \\ □=420/6. \end{gathered}`

We have solved the equation.

Answer

D. □ = 420 ÷ 6
