Answer:
11
Step-by-step explanation:
Those are alternate exterior angles. IF the lines A and B are parallel, then those angles are equal. Set them equal to each other and solve for x:
5x + 9 = 6x - 2
Combine like terms:
11 = x
Answer:
1.5
18 and 33
Step-by-step explanation:2.
c
A + s = 456........a = 456 - s
3.5a + s = 1131
3.5(456 - s) + s = 1131
1596 - 3.5s + s = 1131
-3.5s + s = 1131 - 1596
-2.5s = - 465
s = -465/-2.5
s = 186 <====== student tickets sold
a + s = 456
a + 186 = 456
a = 456 - 186
a = 270 <==== adult tickets sold
Using a calculator, I arrived to answer C because if you enter it in right you arrive at 39.419, rounding it to 39.42
