This would indeed be true
Answer :
1. -3x + 6 = -9
-3x = -9 - 6
-3x = -15
x = -15 / -3
x = 5
2. 5m + 4m = 72
9m = 72
m = 72 / 9
m = 8
3. 6d - 10d = 40
-4d = 40
d = 40 / -4
d = -10
4. 2(x + 4) = 30
2x + 8 = 30
2x = 30 - 8
2x = 22
x = 22 / 2
x = 11
5. 78 = -2(m + 3) + m
78 = -2m - 6 + m
78 = -m - 6
78 + 6 = -m
84 = -m
m = -84
Tan^-1(9.1834) = 83.7854
to the nearest whole degree = 84 deg (83.7 gets rounded to 84)
really hopes this helps
ANSWER
I would put C.
C is the best one there.
The inequality would be 50x+100≥2000
