If the puzzle was solved in 1/5 hour, we can multiply the time it took to solve one puzzle by 5.
2/5(5/1)
=10/5
=2
So she'll be able to solve 2 puzzles in one hour.

Answer:
N = -2M + 110
Step-by-step explanation:
Use the point (70, 20) and (50, 30) to find the slope. Use rise/run.
You go down 20 and right 10, so the rise/run is -20/10 which reduces to -2.
To find the y-intercept, go to the y axis and see where the intersects it which is 110.
N = -2M + 110
M>5=m>4
m>5 and m>7 are on line then m>5+m>7=180
by substituting
m>4+37=180
m>4=143
m>2=m>7=37
m>4=m>8
m<3+m>5=180
