Answer: x = 6
x+x=19-7
2x=12
Hence the answer is x=6
Step-by-step explanation:
lois need to sell 504 pies to get this amount.
7 hours + 6 hours + 6 hours
=19 hours
12 minutes + 46 minutes + 53 minutes
=111 minutes
=1 hour 51 minutes
19 hours + 1 hour and 51 minutes is 20 hours and 51 minutes. This is the total time.
Average time = total time/number of deliveries
(20 and 51/60) divided by 3
=6.95 hours
= 6 hours and 57 minutes
4/7 is the simplest form
You can divide 20 by 5 and get 4 and divide 35 by 5 and get 7
14= 7+7
16= 8+8
18= 9+9
20= 9+11
22= 10+12
24= 12+12
26= 7+8+11
