Answer:
6π
Step-by-step explanation:
(135/360)×π×4²
(135/360)×π×16
=6π
1 1/4 because you must make improper fractions
It’s either A or B but I would choose B as the correct answer
8a+4s=840
a=s+30
8(s+30)+4s=840
12s+240=840
12s=600
s=50
A=s+30
a=50+30
a=80
The drama play sold 80 adult tickets
6x - 6 - 7x = -13/2
Multiply both sides by 2:
12x - 12 - 14x = -13
Simplify:
-2x - 12 = -13
Add 12 to both sides:
-2x = -1
Divide both sides by 2:
-x = -1
Change to a positive value of x:
x = 1
