Answer:
$180
Step-by-step explanation:
To solve, we can set up a proportion and solve.
You earn $45 for 7.5 hours of work, and you earn $ x for 30 hours of work
45/7.5=x/30
Cross multiply
45*30=7.5*x
1350=7.5x
To solve for x, we need to get x by itself. It is being multiplied by 7.5. To undo this, divide both sides by 7.5
1350/7.5=7.5x/7.5
180=x
So, for 30 hours of work, you would earn $180
Answer:
x is greater than or equal to -5 (the second graph)
Step-by-step explanation:
-5c+2<=27
-5x<=25
x>=-5
Every time the y-value decreases by 1, the x-value increases by 2, so the slope is -1/2 throughout the line.
