Answer:
Video Games = $5.25
Movies = $1.25
Step-by-step explanation:
(3x + 5y = 30)2
6x + 2y = 18
Video Games (y) = 5.25
6x + 10y = 60
<u>- 6x + 2y = 18 </u>
(8y)/8 = (42)/8
<u> </u>
6x + 2(5.25) = 18
6x + 10.5 = 18
6x = 7.5
x = 1.25
Double Check by plugging in the numbers
Answer:
A , B , C
Step-by-step explanation:
1) find the slope of the given line
slope = (-a/b) = (-8/4) = -2
two parallel lines have the same slope
A : correct
B : (-a/b) = -16/8 = -2 (correct)
C : correct
D : wrong (2 is different from -2)
Answer:

Step-by-step explanation:
Answer: 33.33 minutes longer.
Step-by-step explanation :
We need to remember the following formula:
Where "t" is the time, "d" is the distance and "V" is the speed.
We know that she runs approximately 5.4 miles per hour, then:
Since she plans to run 9 miles on Tuesday, her run's time on Tuesday will be:
Making the conversion from hours to minutes, we get:
Since she plans to run 12 miles on Thursday, her run's time on that day will be:
Making the conversion from hours to minutes, we get:
Finally in order to find how many longer will her run be on Thursday compared to Tuesday, we need to make the following subtraction:
Answer:
126
Step-by-step explanation:
l*w*h
l=6
w=5
h=3.5
3.5*5=21
21*6=126
