It was just simplifying, was basically in standard form already.
Greetings!
"<span>A rectangular parking lot at the mega-mall is 7/10 mile long and 1/4 mile wide. How much fencing is needed to enclose the lot?"...
This question is essentially asking to solve for the perimeter. The formula for the perimeter of a rectangle is:
</span>

Input the information we already know:

Find A common denominator.

Simplify.



Reduce to Lowest Terms.

or
1 9/10 miles of fencing will be required to enclose the entire lot.
Hope this helps.

Answer:
56 music files
Step-by-step explanation:
From the above question:
Let the number of music files
Arely has = x
Valerie has = y
Arely has 4 fewer than twice as many music files as Valerie.
x = 2y - 4
They have a combined number of 86 music files.
x + y = 86
We substitute 2y - 4 for x in the above equation
2y - 4 + y = 86
3y - 4 = 86
3y = 86 + 4
3y = 90
Divide both sides by 3
3y/3 = 90/3
y = 30
Hence, Valerie has 30 music files.
The number of music files that Arely has is calculated as:
x = 2y - 4
x = 2(30) - 4
x = 60 - 4
x = 56
Arely has 56 music files
Answer:
Infinite
Step-by-step explanation:
2(x-6)+2x=4(x-3) would turn into:
2x-12+2x=4x-12 which would turn into:
4x-12=4x-12 then you could keep going if you wanted:
add 12 to both sides and subtract 4x from both sides:
0=0 (and zero does equal zero so it is unlimited solutions)
