Answer:
11 3/4
31 5/8
Step-by-step explanation:
1. 54 1/2 - 42 3/4
= 109/2 -171/4
= 218-171/4
= 47/4
= 11 3/4
2. 45 3/8 - 11 3/4
= 363/8 -55/4
= 363-110/8
= 253/8
= 31 5/8
Answer:
2 (x + 2) (x - 1)
Step-by-step explanation:
Simplify the following:
2 x^2 + 2 x - 4
Factor 2 out of 2 x^2 + 2 x - 4:
2 (x^2 + x - 2)
The factors of -2 that sum to 1 are 2 and -1. So, x^2 + x - 2 = (x + 2) (x - 1):
Answer: 2 (x + 2) (x - 1)

<span>If Bob works alone for one hour, he will get 1/6 of the yard work done. Working alone for two hours, Bob will get 2/6 = 1/3 of the yard work done. When Bob and Tom work together for two hours to finish the yard work, Bob will have done 1/3 of the work, which means Tom must have done 2/3 of the work in the two hours. Therefore if Tom works alone, the time he would take to finish the yard work is given by:
2/(2/3)=(you can calculate) hours</span>
Answer:
Mean = Mean is all of the numbers added up and divided by the amount of numbers you have added up. Therefore its 414 ÷ 15 = 27.6
Mode = Most common number = 35
Range = Largest number - Smallest number
40 - 5 = 35
Median = 32 (Middle number)
