To find how many miles per hour you need to divide 50 by 5 to get the number of miles per hour and do the same thing to the 2nd step and to find the difference you need to subtract the numbers. Hope it helps!!!

What is the solution to the equation 3x-5=2x+8+x?
Marysya12 [62]
So when solving this you are going to have to solve the equation.
Okay so first thing we need to do is simplify both sides of your equation so:
3x−5=<span>2x+8+x
</span>Simplifying process:
<span><span><span>3x</span>+</span>−5</span>=<span><span><span>2x</span>+8</span>+<span>x
</span></span><span>Combine Like Terms </span>⇒ 3x−5=<span>(2x+x)+(8)
</span><span><span>3x</span>−5</span>=<span><span>3x</span>+<span>8
</span></span><span><span>3x</span>−5</span>=<span><span>3x</span>+<span>8
</span></span>Second thing we are now going to do is s<span>ubtract 3x from both sides<span> so:
</span></span><span><span><span>3x</span>−5</span>−<span>3x</span></span>=<span><span><span>3x</span>+8</span>−<span>3<span>x
</span></span></span><span>−5</span>=<span>8
</span>Final step is to add 5 to both sides:
−5+5=<span>8+5
</span>0=<span>13
</span>The answer to your question is "<span>There are no solutions"</span>

The cost to rent a car is $25 plus an additional $0.15 for each mile the car is driven. Which of the following equations could b
kirill [66]

Answer:

25 + 0.15m = 71.8

Step-by-step explanation:

Given:

Fixed charge = $25

Additional charge for each mile = $0.15

Let number of miles driven be m.

Total Billed amount = $71.80

Now total bill amount is calculated by adding fixed charge with additional charge for each mile times number of miles.

Hence,

Total Billed amount  = Fixed charge + Additional charge for each mile × number of miles driven

25 + 0.15m = 71.8

Hence the equation is 25 + 0.15m = 71.8.
