Answer: 27
Step-by-step explanation:
Luckily the true statement is there, otherwise you'd have to post more. When x = -5,
x^2 + 10 = (-5)^2 + 10 = 25 + 10 = 35
x + x + x = 3x = 3* - 5 = - 15
x^2 + 10 > x + x + x That's the first choice
6.5 lbs/100lbs but what is it out of? 6.5 lbs out of what? 6.5/10 6.5/10000000lbs???
I took the quiz first one is true and the second one is false
Answer:
6 2/5 hrs or 6.4 hours total
Step-by-step explanation:
In two hours, Bob completes 2/10 = 1/5 of the job
Ellen completes 2/ 8 = 1/4
Find amount left
1 - 1/5 -1/4 = 1 - 4/20 - 5/20 = 11/20 left
Ellen will need 8hrs * 11/20 = 88/20 = 4 2/5 hours to finish the job
2 hours to start + 4 2/5 hours to finish = 6 2/5 hours total
