Question

Could somebody help me? :((

Answer 1

Answer: Jenna multiplied both numbers by 5 and added the products of the two equations into her answer. Mia added the numbers then multiplied by 5 to get her answer. However, in some situations, this isn't the case. take 5(9+6) for example. You multiply both by 5 to get 45+30=75. That's correct. And when you add both to get 15, then multiplied by 5, you also get 75. But in certain scenarios, such as dividing, that won't be the case. 5(9/3)=15. (Dividing the 9 by 3 first) 5(9/30) [not dividing first] gets you 3.
