Phil consumed 1,200 calories at lunch. he has a goal of burning at least 5% of those calories by walking on the treadmill. if walking on the treadmill burns 200 calories per hour, which statement best describes how long he should walk on the treadmill?

5% of 1200 calories is 60 calories.

Step-by-step explanation:

b

If he wants to burn 60 calories and walking on the treadmill for an hour burns 200 calories, then you can set up a prportion:

60 cal 200 cal

=

x mins 60 mins

Cross multiply to get 3600=200x

x=18

He would have to walk for 18 minutes in order to burn 5% of the calories he consumed for lunch.

the correct answer is the second option

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
