Answer:
30
Step-by-step explanation:
The factors of 120 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, <u>30</u>, 40, 60, 120
The factors of 150 are: 1, 2, 3, 5, 6, 10, 15, 25, <u>30</u>, 50, 75, 150
Then the greatest common factor is 30.

Answer: 1.66666666667
we current vertices of the given triangle
remember that,
so we obtain:
y=3x+2
For a the equation is y=3x+2 because he makes 3 every hour (3x) and he already has 2 (+2).
For the graph you replace x with any number and solve. Plot the point.
Then you do it again but with a different x.
Finally you draw a straight line trough the 2 points.
