M + s + r = 8500
5m + 6s + 8.50r = 64600
s = 2m
m + 2m + r = 8500
3m + r = 8500
r = 8500 - 3m
5m + 6(2m) + 8.50(8500 - 3m) = 64600
5m + 12m + 72250 - 25.50m = 64600
-8.50m = 64600 - 72250
-8.50m = -7650
m = -7650 / - 8.50
m = 900 <=== 900 matinee tickets
s = 2m
s = 2(900)
s = 1800 <===1800 student tickets
r = 8500 - 3m
r = 8500 - 3(900)
r = 8500 - 2700
r = 5800 <=== regular
Part 1 8.19 meters
11 * .305 = 3.355
8 * .305 = 2.44
3.354 + 2.44 = 8.19
it will cost $252 to cover it
you need 9 square meters to cover 8.19 meters of area
so 9 * 28 = 252
Answer:
Step-by-step explanation:
40cm—0.4m
4000mm=4m
4mm=0.4cm
4m=400cm
40km=40,000m
Can’t see the last box in the left line.
1km=1000m
1m=100cm
1cm=10mm
Answer: 16x - 4
Explanation: Since all of the sides of a square are equal in length by definition, the perimeter of a square is 4 times its side length. 4(4x-1) is 16x - 4 when simplified.
Answer:
x=2, mn=ol=7
Step-by-step explanation:
by definition of a parallelogram we can see that the 2 lines are equal and therefore x+5=2x+3 which we can solve and get x=2. We can put the x=2 back into either line to solve since the 2 lines have equal length. Done!
