Answer:
A) 112 3/4 inches
___
B) 5.555 inches
Step-by-step explanation:
Each tile has its own constant width of 2 3/4 in. and length of 5 1/2 in.
The width of the sidewalk is 9 tiles wide; therefore, the width in inches can be found by calculating 9 x 2 3/4
The length of the sidewalk is 25 tiles long; therefore, the width in inches can be found by calculating 25 x 5 1/2
Sidewalk: W = 24 3/4 in. L = 137 1/2 in.
A) L-W
B) L/W
A and b are the minutes spent on machine A and machine B, respectively.
a+b = 40
b = 40-a
8a + 6b = 300
8a + 6(40-a) = 300
8a + 240 - 6a = 300
2a = 60
a = 30
b = 40-a = 10
30 minutes on machine A and 10 minutes on machine B
