Answer:
30 Lower level tickets
17 upper level tickets
Step-by-step explanation:
Let:
Lower level tickets = l
Upper level tickets = u
5l + 9u = 303 - - - (1)
8l + 10u = 410 - - - - - (2)
Multiply (1) by 8 and (2) by 5
40l + 72u = 2424 - - - (3)
40l + 50u = 2050 - - - (4)
Subtract (3) from (4)
22u = 374
u = 374 / 22
u = 17
Put u = 17 in (1)
40l + 72(17) = 2424
40l + 1224 = 2424
40l = 2424 - 1224
40l = 1200
l = 1200 / 40
l = 30
30 Lower level tickets
17 upper level tickets

Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
We are told that a right angle is divided into two parts
A right angle = 90°
Part A = 30°
Part B = 4x
Hence:
30° + 4x = 90°
Collect like terms
4x = 90° - 30°
4x = 60°
4x = 60/4
x = 15
Therefore, the value of x = 15
Answer:
