Answer:
6 hours
Step-by-step explanation:
total: 540 mi
drove motorcycle: 40mph
drove car: 60 mph
11 hours
equation for miles: 540=40x+60y
equation for time: 11=x+y
11=x+y
-x -x
y=-x+11 <---- plug in
540=40x+60(-x+11)
540=40x-60x+660
-660 -660
-120=-20x
/-20 /-20
x=6
6 hours
Answer:
132 in^2.
Step-by-step explanation:
The top line has length 3 + 8 + 3 = 14 inches
The whole figure is a trapezium and its area is:
1/2 * h * (a + b) where h = the height and a and b are the lengths of the parallel sides
So we have Area 1/2 * 12 * ( 8 + 14)
= 6 * 22
= 132 in^2.
(5!*5/4!)
= -
