You have to do the inverse operation, or subtraction: 199 - 87 = 112

Which equation can be used to find the answer?

Christina climbs to the top of Mount Graham in Arizona. On the first day, she climbs to an elevation of 1029 ft. The elevation of Mount Graham is 10,724 ft. How many total feet of Mount Graham’s elevation does Christina climb on the other days?

A.
e + 1029 = 10,724
e = 9695
9695 ft

B.
e = 1029 · 2
e = 2058
2058 ft

C.
e = 10,724 ÷ 2
e = 5362
5362 ft

D.
e – 1029 = 10,724
e = 11,753
11,753 ft

:D

Answer 14

This problem is basically a subtraction problem, because it's subtracting 96 from whatever the number was originally. The inverse of subtraction is addition, so: 96 + 172 = 268 is your answer

Answer 15

Thanks!:)

Answer 16

No problem. Do you have any more?

Answer 17

Yeah 1 more after this 1 i'm fixing to post

Answer 18

C

This is an addition problem, because you're adding x number of stamps to completely fill the book. So we would do subtraction to find out what x is. 54 - 38 = 16

Answer 19

Thank you again

Answer 20

D

This is subtraction, because 23 were sold. So you have to add 23 to the amount she has left: 112 + 23 = 135
