1st question answer is owning a dog or owning a cat

the second question answer is 7

Step-by-step explanation:

1)mutually exclusive means 2 things that cannot happen at the same times. so its asking which is NOT an example so u can own a dog and a cat at the same time

2)the answer is 7 because 11 ppl buy contact lenses and 4 people buy glasses. 11-4=7

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
