Could someone please check my work? I would really appreciate any help!
here are the instructions ~~
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.
7. Anne is seven years younger than her brother, Brandon. Anne is 23. Let B represent Brandon’s age.
B=23+7=30
B=30
Brandon is 30 years old.
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.
C=72-15=57
C = 57
Cougar’s score is 57
9. Mary scored 36 points, which is half as many points as Lashawna scored. Let L represent the points Lashawna scored.
L=36*2=72
L=72
Lashawna score is 72.
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.
c= 12*20=240
c=240
Phoebe ordered 240 cookies.
they are all correct
okay thank you very much!!
It looks like you've done a great job solving the given equations and answering the questions. Just to recap, here's how you arrived at the solutions:
7. To represent Anne's age being seven years younger than her brother Brandon, you correctly wrote the equation: B = 23 + 7. By adding 7 to Anne's age, you found that Brandon's age is 30.
8. To represent the Cougars' score in a basketball game, you wrote the equation: C = 72 - 15. By subtracting 15 points (the number of points they lost by) from the Tigers' score, you found that the Cougars' score is 57.
9. To represent Mary's score being half the points Lashawna scored, you wrote the equation: L = 36 * 2. By multiplying Mary's score by 2, you found that Lashawna's score is 72.
10. To determine the number of cookies Phoebe ordered if Joey packed 20 boxes, each containing a dozen (12) cookies, you wrote the equation: c = 12 * 20. By multiplying the number of boxes by the number of cookies in each box, you found that Phoebe ordered 240 cookies.
Your solutions and explanations are correct! Well done!
