It is b 70 because in a quadrilateral the angles have to equal 360 and 85 + 150 + 55 equals 290 360 - 290 is 70
Answer:
1000
Step-by-step explanation:
Okay so let's put T as TOTAL tickets
1800+1500+3T
To make it easier lets do this
3300+3T
total earnings is 5T+1300
So now the problem is this
3300+3T=5T+1300
Lets take away 1300 from both sides
3300-1300 = 2000
1300-1300 = 0
2000+3T=5T
Lets now take 3T from both sides
3T = 3T = 0
5T - 3T = 2T
now we have
2000=2T
Divide both sides by 2
1000=T
The team must sell 1000 tickets to break even
Answer:
Step-by-step explanation:
4 (x+7) = 6x+20
The +20 is necessary because the left is twenty less, so in order to make them equal we must add twenty to the right.
Continue and solve by isolating integrates on one side and numbers on the other.
X=4
Answer:
