Question

Nari says, “The sum of 10 and one-third of a number is 25.” She uses the bar model to write an equation to represent her statement.
Which equation can Nari write using the bar model?

Answer 1

Answer:

A

Step-by-step explanation:

Just took the unit test! :)

Answer 2

It says the sum, which hints that the two numbers will be added

So we can start the equation with 10+(1/3n)

we are then told they add up to 25
So they will equal 25

So the equation is
10+(1/3n)=25
