Karen walked 3.5 miles to her friends house. She wants to express this distance in feet. Write a proportion to find the number of feet Karen walked.

1 mile = 5,280 feet

Step-by-step explanation:

1 mile=5280 feet

2 miles=10560 feet

3 miles=15840 feet

3.5 miles=18480 feet

1 mile= 5280 feet

3.5 miles=    x

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
