Answer:
Cara multiplied only 4 and 7 together and did not multiply 4 and 13.
Step-by-step explanation:
Let us evaluate the given expression step by step,

We can evaluate this expression in two ways; either by subtracting -13 from 7 and then multiply by 4 or by multiplying 4 to 7 and -13.



Now let us see where Cara made an error. We can see Cara just multiplied only 4 and 7 together and did not multiply 4 to 13.
Therefore, Cara made error in her first step.

I'm not sure but I hope this helps
4+8x and 4 (2x+1)
4+16 and 4 (4+1)
20 and 4 (5)
20 and 20
Because he drove 1542.75 miles in 3 days, you would have to divide 1542.75 by 3 to figure out how many miles he drove in one day.
1542.75/3 = 514.25
Then to figure out how many miles he drove per hour, you would divide 514.25 by 8.5, which is the same as 8 1/2 hours.
514.25/8.5 = 60.5
So the answer is 60.5 mph
