Answer:
The equation is <u>5 + n = 12</u> and Torry ate<u> 7 </u>ice cream sandwiches.
Step-by-step explanation:
Given:
Molly and Torry like to eat ice cream sandwiches. In one week, Molly ate 5 ice cream sandwiches, and Torry ate n ice cream sandwiches. They ate a total of 12 ice cream sandwiches all together.
Now, to write an equation to describe this situation and to find number of ice cream sandwiches Torry eat.
Molly ate = 5 ice cream sandwiches.
Torry ate =
ice cream sandwiches.
Total ice cream sandwiches = 12.
So, to write an equation of this situation:

Now, to find the number of ice cream Torry ate:

<em>Subtracting both sides by 5 we get:</em>

<em><u>Torry ate = 7 ice cream sandwiches</u></em>.
Therefore, the equation is 5 + n = 12 and Torry ate 7 ice cream sandwiches.
