Which equation can be used to find the answer?

Usman paints the entire length of a fence in a day. He paints the last 12 m of the 38 m fence in the afternoon. How many meters of the fence does he paint in the morning?



A.


f = 38 ÷ 2

f = 19

19 m


B.


f – 12 = 38

f = 50

50 m


C.


f = 12 · 2

f = 24

24 m


D.


f + 12 = 38

f = 26

26 m

Answer 1

@kai47

Answer 2

i think it is B

Answer 3

hint: the x and 12 combine to form the 38

Answer 4

26?

Answer 5

so it would be D

Answer 6

what equation forms before you get 26

Answer 7

i don't know, all i know is that i memorized that 12 + 26 always = 38

Answer 8

if you replace the 26 with a variable f, you'll get f+12 = 38, agreed?

Answer 9

yes!

Answer 10

ok great

Answer 11

also can you verify this?, like just tell me if im wrong?

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

Answer 13

i think it is A

Answer 14

yep it's the same idea as the last problem (just imagine instead of the distances being horizontal, they're now vertical)

Answer 15

Okay thanks!

Answer 16

no problem

Answer 17

you really helped!
