Start with
![\dfrac{5-2x}{3}+1-\dfrac{3x-2}{5}=-x](https://tex.z-dn.net/?f=%5Cdfrac%7B5-2x%7D%7B3%7D%2B1-%5Cdfrac%7B3x-2%7D%7B5%7D%3D-x)
Multiply both sides by 15 to get rid of denominators:
![5(5-2x)+15-3(3x-2)=-15x](https://tex.z-dn.net/?f=5%285-2x%29%2B15-3%283x-2%29%3D-15x)
Expand the left hand side:
![25-10x+15-9x+6=-15x](https://tex.z-dn.net/?f=25-10x%2B15-9x%2B6%3D-15x)
Move all terms involving x to the left and all numbers to the right:
![-10x-9x+15x=-25-15-6](https://tex.z-dn.net/?f=-10x-9x%2B15x%3D-25-15-6)
Sum like terms:
![-4x=-46](https://tex.z-dn.net/?f=-4x%3D-46)
Divide both sides by -4:
![x=\dfrac{46}{4}=\dfrac{23}{3}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B46%7D%7B4%7D%3D%5Cdfrac%7B23%7D%7B3%7D)
Answer:
The customer would have to rent two DVDs in order for the two amounts to be both $15
Step-by-step explanation:
$7(the membership fee)-$15(unlimited plan)= $8 remaining
then you would divide 8 by four to see how many DVDs would have to be rented in order for the totals to be the same
The final cost of the computer can be calculated as ...
(original cost)*(1 -0.20)*(1 +0.04)
= $750*0.80*1.04 = $624.00
The ending balance on Hakim's bank account is
$700 +700*.05 = $735.00
The amount remaining after Hakim pays for the computer is
$735.00 -624.00 = $111.00
M is -7/2 and b is 0
The m is the rate of change and it is always the coefficient of the X. The b is the constant in the equation and in this case there is none so it is 0.
