Let a = Adult tickets, s = Student tickets; we are going to set up a system of equations.
8a + 4s = 880
a - s = 20
We are going to multiply the second equation by so that we can cancel out one of the variables and solve for the other. This gives you:
8a + 4s = 880
4a - 4s = 20
Notice the s-variables will cancel:
12a = 900
a = 75
Now we plug in the amount of adult tickets to solve for the student ones.
75 - s = 20
- s = - 55
Divide both sides by - 1
s = 55.
There were 55 student tickets sold and 75 adult tickets.
The coordinate points (-2,-6) and (-6,10) written in slope-intercept form is...
y = -4x + -14
5/6 = 50/60
3/4 = 45/60
7/10 = 42/60
So as we can see 5/6 is the greatest
Answer:
8x2−8xy−6y2
Step-by-step explanation:
if your answer choices contain exponents then of course the number behind the x's are exponents.
