There are 49,000 seats in a sports stadium. Tickets for the seats in the upper level sell for $25, the ones in the middle level
snow_tiger [21]
U- amount of upper level tickets which cost 25$
m-amount of middle level tickets which cost 30$
b-amount of bottom level tickets which cost 35$

m+b=u and
m+b+u=49000 and
25u+30m+35b=1419500

putting u from first equation to the second
2u=49000
u=24500 - seats in upper level
m+b=24500 so m=24500-b
25*24500+30(24500-b)+35b=1419500
612500+735000-30b+35b=1419500
1347500+5b=1419500
5b=72000 /:5
b=14400

A triangle contains angles mesuring 28 degrees and 37 degrees. How many degrees is the third angle?​
Orlov [11]

Answer:

  • 115°

Step-by-step explanation:

<u>We know that:</u>

  • Angles ∠A and ∠B are 28° and 37°.

<u>We don't know:</u>

  • Angle ∠C's angle

<u>So, we do this:</u>

  • Add the 180°
  • Solve the equation 180 - 28 - 37

<u>Solve:</u>

  • 180 - 28
  • = 152 - 37
  • = 115.

Angle ∠C is 115°.
