Answers

Answer:

x = 14

y = 39

A. 114F degrees

Step-by-step explanation:

well for the first one they're asking for a simliar ratio to show the relationship between all of the points

so we must line up and simplify all the points to try and find a simliar ratio

so the ratio is 2/3

because if we simplify 8/12 and 16/24 they both come down to 2/3

so if we plug that in to find x we get x = 14

and then if we that in for y we get y = 39

now for the second question this is a pretty simple addiction subtraction kind of problem but here's some help

if the highest temperature was 93 and the lowest was -21 we just have to find how many degrees are in between those two

therefore leaving us with the answer

A. 114F degrees

the school raised money for new playground equipment. They sold candy bars for 2$ each. They Sold 143 on Monday, 200 on Tuesday, and 56 on Wednesday. How Much Money did they raise?

Answers

Answer:

I think the answer is $798

Step-by-step explanation:

143×2=286

200×2=400

56×2=112

286+400+112=$798

They earned $798

The first thing you have to do in order to find your answer is add up the total amount of candy bars sold for the total 3 days. Then once you have that added up, multiply it by 2 (since they were worth 2 dollars each) and you will come up with $798 total.
