Answer:
The Ans is A
Step-by-step explanation:
using midpoint fomula
(x,y) = (m1x2 +m2x1/m1+m2) ,(m1y2+m2y1/m1+m2)
3x+12+5x+5=25
8x+17=25
8x=8
x=1
123-61.25=61.75. Allison weighs 61.75 pounds.

Answer:
M = (S -C)/C
Step-by-step explanation:
Starting with ...
S = C + MC
we want to solve for M.
S - C = MC . . . . subtract the term not containing M
(S -C)/C = M . . . . divide by the coefficient of M
Solved for M, the formula is ...
M = (S -C)/C
