70 = 4x
x equals the number of movies
divide both sides by 4
70 / 4 = x
17 .5 = x
Anderson will be able to go to 17 movies
Answer:
g = -2
Step-by-step explanation:
g = -5r + 13
r = 3
You substitute three for r in the equation.
--------------------------------------------------------------
g = -5(3) + 13
--------------------------------------------------------------
Distribute -5 to 3
--------------------------------------------------------------
g = -15 + 13
--------------------------------------------------------------
Solve
-------------------------------------------------------------
g = -15 + 13
-15 + 13 = -2
g = -2
Taking point (0,-2) of graph one and replacing in the equation;
2x+3y=6
2(0)+3(-2)=6
-6=6
So graph isn't the required graph.
Taking point (0,2) of graph 2;
2x+3y=6
2(0)+3(2)=6
6=6
So, graph 2 is the required graph.
The average number of hours can be calculated using the following rule:
average number of hours = total number of hours / total number of weeks
total number of hours = 36 3/8 + 41 1/4 + 40 1/2 + 38 3/8 = 313/2 hours
total number of weeks = 4 weeks
Average number of hours per week = (313/2) / (4) = 39 1/8 hour
Based on the above calculations, the correct answer is:
C. 39 1/8 hour
