17/8 -11/3
51/24-88/24
-37/24 simplified is -1 13/24
Answer:
8a - 7
Step-by-step explanation:
First, subtract 12a from 20a
20a - 12a
= 8a
Now, subtract -3 from -10.
Subtracting a negative number is the same as adding a positive number, so add 3 to -10.
-10 + 3
= -7
Put together 8a and -7
8a - 7
So, the simplified expression is 8a - 7

Step-by-step explanation:
It is not A because if they were riding for a constant speed the entire ride it would just be a straight line going up and that line is curved.
It is B because in the chart you see that from hour 3 to hour 4 they did not move at all (this is why it is a flat horisontal line) and you can infer that they stopped and took a break.
It is not C because they stopped and took a break at hour 3 to hour 4.
It is not D because they never decreased their milage.
