Answer:
your question makes no sense
I don't think you have the correct options. 9/12 + 6/12 = 15/12. To simplify, you divide each value by 3 and get 5/4, which, as a mixed number, would be 1 1/4, and neither 5/4 or 1 1/4 is an option. I hope this helps!
Answer:
1,582 miles
Step-by-step explanation:
395.5 x 4 = 1582
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
(-10,-4)
m=-12
y+4=-12(x+10)
y+4=-12x-120
y=-12x-124
