Answer:
c., d., f
Step-by-step explanation:
"elana walked 12 miles"
That is 12.
"then she walked 1/4 that distance"
That is 1/4 of 12 miles, so it is 1/4 * 12
She walked altogether
12 + 1/4 * 12 = 12 + 3 = 15
She walked altogether 15 miles.
a.12+1/4 = 12.25 which is not 15
b.12×1/4 = 3 which is not 15
c.12+1/4×12 = 12 + 3 = 15 which is correct
d.12(1+ 1/4) = 12(1.25) = 15 which is correct
e.12×3/4 = 9 which is not 15
f.12×5/4 = 15 which is correct
Answer: c., d., f
Answer:
7.5 or 15/2
Step-by-step explanation:
x-3x+6=2x-24 -- Combine like terms
-2x+6=2x-24 -- Add 2x to each side
6 = 4x-24 -- add 24 to each side
30 = 4x -- divide by 4
15/2 or 7.5 = x
