Answer: 0.9
Step-by-step explanation:
Mark me branliest please
S+D+K=155
K=S+10
D=S-20
--------------------------------
S+(S-20)+(S+10)=155
S+S-20+S+10=155
3S-10=155
3S=165
S=165/3=55
---------------------------------
If S=55,
K=55+10=65
D=55-20=35
---------------------------------
Therefore, Sarah had worked for 55 hours, Kate had worked for 65 hours and Dave had worked for 35 hours.
Well assuming that the riders get off so that others may get on it'll get pretty busy, just take the 3hrs. and convert them into min so that would be 180 min. then you divide the 180 min by 25 min. This will give you 7.2. You then multiply this 7.2 to the 35 people to get 252 people.

Step-by-step explanation:
-7x+12-2x=23+13x
First take away 13x from the right side and put it on the left side adding taking it away from -7x
-7x(-13x)=-20x
-20x+12-2x=23
then add 2x to -20x
and move 12 to the other side, minus it off of 23
-18x=11
then divide -18x on both sides
then x=-11/18
