Answer:
487.5
Step-by-step explanation:
A=a+b/2 x h
Answer:
B. 59°
Step-by-step explanation:
<AOC=77°
<BOC=?
THEREFORE,
<AOC=<BOC+<AOB
77° =7x+17+3x
77°-17=7x+3x
60=10x
x=60/10
x=6°
Now,
<BOC=7x+17
=7*6+17
=42+17
=59
-45x+72
you multiply the 9 by everything in the parentheses
Let the amount of adult tickets sold be x
Since the total of 380 tickets sold consists of the amount of adult tickets and the amount of children tickets that are 70 fewer:
x + (x - 70) = 380
2x - 70 =380
2x = 450
x = 225
Therefore, the amount of adult tickets sold is 225
Take the square root of both sides of the equation to eliminate the exponent on the left side.
x=0
