X = small van capacity, y = larger van capacity
y = x + 6
2x + y = 57
now we sub in x + 6 for y
2x + x + 6 = 57
3x + 6 = 57
3x = 57 - 6
3x = 51
x = 51/3
x = 17
y = x + 6
y = 17 + 6
y = 23
small van (x) has 17 seats and large van (y) has 23 seats
Answer:
Idk too much brain hurt
Step-by-step explanation:
Divide 331 by 4.5
331/4.5= 73.555555555555 so you can round to 73.6 mph
80 square units
______________________________________________
The Formula for the area of a trapezoid is A= (a+b/2)h
A= 3+17/2 (8)
A= 20/2 (8)
A= 10 (8)
A = 80
There are 6/10 left over. 6/10 reduces to 3/5.
