Question

After a gymnastics competition, the coaches reviewed all the gymnasts’ scores to identify areas for improvement. A missed landing on an aerial cartwheel deducts 2 points from the score. The coaches found that aerial cartwheels were missed 5 times across the competition.

Question 1
Part A

Which multiplication and addition equation models how these missed landings affect the scores overall?


5(−2)=−2+(−2)+(−2)+(−2)+(−2)=−10

2(2)=2+2=4

2(−2)=(−2)+(−2)=−4

5(2)=2+2+2+2+2=10
Question 2
Part B

How did these missed landings affect the scores overall?

Select the correct word or number from the drop-down lists to complete the statement.

Overall, missed landings on aerial cartwheels
the scores by
points.

Answer 1

A.) 5(−2)=−2+(−2)+(−2)+(−2)+(−2)=−10

B.) The overall score lost 10 from the total score

C. ?) See Below

Explanation:

For Part A when multiplying you are saying take this number so many times. In this example, we are taking -2 5 times. And just like when you take an apple and it adds to your amount of apples as many learned when younger, so too do we add here.

5 x (-2) = (-2)+(-2)+(-2)+(-2)+(-2) = -10

***It is of note that any time you multiply a negative by a positive you must get a negative.***

For Part B We know that a missed landing deducts 2 points from the score and that she had 5 missed landings. From Part A we know this results in a -10 point deduction.

Overall, missed landings on aerial cartwheels Diminishes (or some other word that means subtracts) the score by 2 points.
