Answer:
1. Neither pair is a solution
Step-by-step explanation:
3*3=9 -18*4=-32 9(-)-32=41 not eleven
4*3=12 4*4=16 12-16=-4 not eleven
Speed = distance / time . . . . . . . . easy to remember: speed is usually miles/hour
43 231/905 = (6 +17)/((6/37 +t) . . . . t is the travel time from Megan's to Sarah's
6/37 +t = 23/(43 231/905) = 905/1702
t = 905/1702 -6/37 = 17/46
The average speed for the trip from Megan's to Sarah's was (17 mi)/(17/46 h) = 46 mi/h.
Step-by-step explanation:
The area of the triangle is, 8×6/2 = 24 in²
The area of the rectangle is, 8×4=32 in²
The area of the irregular figure is,
(24+32) in²
= 56 in²
