Answer:
15x + 40 = 115
We set the equation to 115 because the total cost is $115.
We add the "+ 40" because of the $40 to rent the trailer for the day.
The 15x is because it represents the miles per hour (x) times the number of hours.
The number of hours times the charge per mile, plus the $40 to rent it, will equal $115.
Hope this helps!!
Answer:

Step-by-step explanation:
100/1.7=58.8
Because a ║b you can say:
-60 -2x = -70 -4x ⇒ -2x + 4x = -70 + 60 ⇒ 2x = -10 ⇒ x = -5 :)))
i hope this is helpful
have a nice day
Answer:
The length of the rectangle is 30 feet.
Step-by-step explanation:
Because the equation for area is length times width, you would have to set the two equations to seventy and multiply them.
<em> (x+5) (x+2) = 70</em>
<em> </em><em>2x + 10 = 70</em>
Then, you would have to subtract ten from both sides, cancelling it from the left side.
<em> 2x = 60</em>
<em />
Then do the opposite and divide sixty by two, therefore getting a length of thirty feet.
