Answer:
132 people bought balcony tickets and 450 bout ground tickets
Step-by-step explanation:
let x be balcony and y for ground
x+y=582
15x+10y=6480 solve by adding(subtracting)/eliminating process
multiply first equation by 15 to eliminate x:
15x+15y=8730
15x+10y=6480 subtract
15x+15y-15x-10y=8730-6480
5y=2250
y=2250/5=450
x+y=582
x=582-450=132
Answer:
y= positive 7
Step-by-step explanation:
Area = 0.5 x (a+b) x h
= 0.5 x (15cm + 6cm) x 1/5cm
= 0.1 x 21cm
=2.1cm^2 (2.1 centimeters squared)
