Answer:
c
Step-by-step explanation:
Notice that there are two variables-- gender and preference-- this is where the two in two-way
Adult tickets cost $10 each and student tickets cost $6 each.
Given:
Kyle's family bought 4 adult tickets and 2 student tickets for $52
Maria's family bought 3 adult tickets and 5 student tickets for 60.
Let us assign x as the adult tickets and y as the students tickets
Kyle's family: 4x + 2y = 52
Maria's family: 3x + 5y = 60
Let us find the value of x using Kyle's equation:
4x + 2y = 52
4x = 52 - 2y
x = (52 - 2y)/4
x = 13 - y/2
Substitute the value of x in Maria's equation to find y.
3x + 5y = 60
3(13 - y/2) + 5y = 60
39 - 3y/2 + 5y = 60
- 3y/2 + 5y = 60 - 39
- 3y/2 + 5y = 21
2(-3y/2 + 5y) = 2(21)
-3y + 10y = 42
7y = 42
7y/7 = 42/7
y = 6
x = 13 - y/2
x = 13 - 6/2
x = 13 - 3
x = 10
To check:
Kyle's Family Maria's Family
4x + 2y = 52 3x + 5y = 60
4(10) + 2(6) = 52 3(10) + 5(6) = 60
40 + 12 = 52 30 + 30 = 60
52 = 52 60 = 60
Answer:
See Below (it is correct)
Step-by-step explanation:
First point given ---- A(-3,0)
2nd point given ----- B(4,0)
The slope is the "change in quantity y" divided by "change in quantity x"
The change would be from 2nd point to 1st point. So,
Change in quantity y is 0 - 0 = 0
Change in quantity x is 4 - (-3) = 4 + 3 = 7
So, slope would be:
Slope = 0/7 = 0
The slope is 0 (which means it is a horizontal line)
Answer:
Step-by-step explanation:
18/5 x -25/3
6/1 x -5/1 = -30
cross cancel the 18 & 3. Also the 5 & -25
