Answer:
the answer is 18 i just got it on usa test prep
For the gym to seat 650 people, including 176 in the bleachers, there must be 650-176=474 chairs. If those chairs are arranged in 25 rows, there must be
... ceiling(474/25) = 19
chairs in each row.
_____
One of the rows can have only 18 chairs. The "ceiling" function returns the smallest integer not less than its argument.
The two interior angles that are not supplemantly (adjacent) to the exteroir angle add up to the exterior angle. Therefore we have:
3x+2x=150
5x=150
x=30.
Since it asked for angle BAC, therefore we have:
30 x 2 = 60.
The answer is C.
Hope this helps!
Answer:
Answer:
x=6, y=63
Step-by-step explanation:
since both equal y, they equal each other-
8x+15=x+57
7x=42
x=6
then to solve for y-
y=(6)+57
y=63
