Answer:
The answer is B
Step-by-step explanation:
This is a system of linear equations. First, you can add the two equations together to eliminate the y so that you can solve for x:
-5x + -7x = 0 + -96
-12x = -96
x = 8
Use x to solve for y:
-5 * 8 + 8y = 0
Add 40 to both sides and divide by 8:
y = 5
So, x = 8 and y = 5.
First you need to find out about how many people went on the roller coaster in one hour by doing 360 divided by 3 and you would get 120. So then you would try to find out how many people went on the coaster in 7 hours by doing 360 times 2 because 3 hours multiplied by 2 is 6 and you would do that to find out how many people went on the coaster in 6 hours, and you would get 720. Next, you have 1 more round of people, so you need to do 720 + 120 which is 840. So about 840 people rode the coaster in 7 hours. Hope this helped.
Answer:
D. ADC EBC
Step-by-step explanation:
cb & cd have that little line showing they're the same
Hello there!
In order to graph the solution, we need to solve it first.
So let's start....
3/7(35x - 14) ≤ 21x/2 + 3
15x -6 ≤ 21x/2 + 3
15x - 21x/2 ≤ 3 + 6
9x/2 ≤ 9
x ≤ 9* 2/9
x ≤ 18/9
x ≤ 2
See the picture for the graph
Please let me know if you have questions about the answer.
Thanks!
