Answer:
should be -7.5
Step-by-step explanation:
4.9×5=24.5
17-24.5=-7.5
Since A is the midpoint of BC, we can assume BA and AC are equal to each other.
We also know that BC = BA + AC = 23 + 23 = 46
Equation 1 x=-16
Equation 2 m=-3
Equation 1
3x-x=-24-6
2x=-32
x=-32/2
x=-16
Equation 2
-2m=16-10
-2m=6
m=6/-2
m=-3
