Hello from MrBillDoesMath!
Answer:
60
Discussion:
As JG bisects FJG,
FJG = GJH =>
2x + 4 = 3x-9 => subtract 2x from each side
4 = 3x -2x - 9 => simplify
4 = x - 9 => add 9 to both sides
4 + 9 = x
x = 13
Now, FJH =
FJG + GJH
(2x + 4) + (3x-9) =
5x -5 => substitute x 13
5(13) -5 =
65 - 5 =
60
Thank you,

Answer:
Step-by-step explanation:
5x + 13y = 232
12x + 7y = 218
For each choice:
a) The first equation can be multiplied by –13 and the second equation by 7 to eliminate y. So we have
- 65x - 169y = - 3016
84x + 49y = 1526
Can not eliminate x and y.
b) The first equation can be multiplied by 7 and the second equation by 13 to eliminate y. So we have
35x + 91 y = 1624
156x + 91y = 2834
Can not eliminate x and y if we ADD.
<em>(If we subtract, this is Yes)</em>
<em></em>
c) The first equation can be multiplied by –12 and the second equation by 5 to eliminate x.
-60x - 156y = - 2784
60x + 35y = 1090
The answer is YES
d) The first equation can be multiplied by 5 and the second equation by 12 to eliminate x.
25x + 65y = 1160
144x + 84y = 2616
Can not eliminate x and y
The final answer is C
