Question

I have to write an equation to represent these real-life situations in which the variable is on the left side of the equation with an operation and a number. Then solve the equation showing the steps. Finally answer the question in a complete sentence as indicated in the lesson content.

7. Anne is seven years younger than her brother, Brandon. Anne is 23. Let B represent Brandon’s age.


8. Last Friday, the Cougars lost to the Tigers in basketball by 15 points. The Tigers scored 72 points. Let C represent the Cougars' score.

9. Mary scored 36 points, which is half as many points as Lashawna scored. Let L represent the points Lashawna scored.


10. Joey owns a small bakery and today Phoebe has ordered c cookies. If Joey boxes the cookies by the dozen and has packed 20 boxes, how many cookies has Phoebe ordered? Let c represent the number of cookies.

Answer 1

This is called "variable abuse"

There is absolutely no need to introduce variables if the whole process takes only one step

e.g. #8, all you have to say is
Cougar's score = 72-15 = 57
(I suppose you want C = 72-15 = 57)

every one of your problems takes only one arithmetic step to solve

Answer 2

Okay thank you! If i work the other ones out would you mind checking them for me?
