33.56 plus 41.98 = 75.54(total reading time for Hector)
31.61 plus 42.08= 73.69(total reading time of Liam)
75.54 minus 73.69= 1.85 more reading time than Liam
ANSWER:Hector read for 1.85 more minutes than Liam
The answer is 14 bolts.
1 dozen bolts have 12 bolts.
7 dozen bolts have x bolts
___
1 : 12 = 7 : x
x = 7 * 12 : 1
x = 84 bolts
1 bin has 7-dozen bolts (84 bolts).
1/6 bin has x bolts
1 : 84 = 1/6 : x
x = 84 * 1/6 : 1
x = 84/6 = 14 bolts
Answer:
5 hours
Step-by-step explanation:
First, you set the equations equal, so 20h=17h+15
Second, you isolate the h, so you would subtract 17h from both sides, giving you 3h=15
Last, you divide both sides by 3 giving you h=5, meaning the companies charge the same price after 5 hours.
