If JM = 5x – 8 and LM = 2x – 6, which expression represents JL?
1 answer:
Answer:
The expression represents JL is<u> 3x - 2</u>.
Step-by-step explanation:
Given:
JM = 5x – 8 and LM = 2x – 6.
Now, to find expression represents JL.
JM = JL + LM
<em>Subtracting both sides by LM we get:</em>
JM - LM = JL.
JL = JM - LM
Now, putting the expression to get JL:
Therefore, the expression represents JL is 3x - 2.

Answer:
$70.56
Step-by-step explanation:
Lets convert the mixed number (trip length) to decimal.
We know 3/5 (by long division) is 0.6, so 705 3/5th = 705.60 miles
Now, let's come to the problem:
1 gallon = 28.8 miles (mileage)
or
$2.96 = 28.8 miles
To find cost per mile, we divide:
That means, it costs $0.10 per mile
Since we want to travel 705.60 miles, we multiply to find the cost:
$0.10 per mile * 705.60 miles = $70.56
