(6m + 5m) + (7n - 3n)
11m + 4n </span>← answer
Answer:
B
Step-by-step explanation:
The inequality is
3x-5y>=10
You can substitute each of the choices in the inequality (on the left side) to see if the result is >=10.
A: 3(1)-5(4)=3-20=-17 not good.
B: 3(6)-5(-3)=18+15=33 good
Y-585 = -7.5(x-15)
y = -7.5x - 7.5(-15) + 585
y = -7.5x + 697.50
C = -7.5(52) + 697.50 = $307.50
