About 10 hrs because he got at least 11 hours of sleep
Answer:
B
Step-by-step explanation:
2x+8=9
you want to isolate the variable so you subract 8 from both sides
2x=1
now you want x by itself so you divide by 2 on both sides
x=1/2 or x=0.5
Hope this helped :)
A. Roc= 14a/d (he can harvest 14 acres per day) so to get 120 acres of wheat he would have to harvest wheat for a little over 5 and a half days

(=^_^=)
160+100+180+60=500
180/500=0.36=36%
50x36%=18
That's your answer lovely~
