Answer:
35 mins lost
out of 3 and 1/2 hrs = 3.5 x 60 mins = 210 mins
%time lost = time lost/total time x 100
= 35/210 x 100
= 1/6 x 100
= 16.66666 %
Answer:
Elena could tell without finishing by simplifying both sides. The next step would have been 30x +24x = 30x+24. This would have been simplified down to x=1
Step-by-step explanation:
Answer:
b = 131
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees

b = 180-49
b =131
Answer:
the answer is D.
Step-by-step explanation:
(2s-5+4s-13)*2=108
(6s-18)*2=108
12s-36=108
12s=108+18
s=12
2*12-5=24-5=19 mi
4*12-13=48-13=35 mi
