B. First pizza:-  1 - 1/3 = 2/3 had been eaten.
   Second pizza:-  1 - 1/4 = 3/4 was eaten.
   Third pizza:-   1 - 1/6  = 5/6 was eaten.

2m/(2m 3)-(2m)/(2m-3)=1how many extraneous solutions does the equation have?
Slav-nsk [51]
\frac{2m}{2m+3} - \frac{2m}{2m-3} =1 \\  \frac{2m(2m-3)-2m(2m+3)}{4m^2-9} =1 \\  \frac{4m^2-6m-4m^2-6m}{4m^2-9} =1 \\  \frac{-12m}{4m^2-9} =1 \\ -12m=4m^2-9 \\ 4m^2+12m-9=0 \\ m=0.6213 \ or \ m=-3.6213
For m = 0.6213, \frac{2(0.6213)}{2(0.6213)+3} - \frac{2(0.6213)}{2(0.6213)-3} \\  \frac{1.2426}{4.2426} - \frac{1.2426}{-1.7574} =0.2929+0.7071=1
For m = -3.6213, \frac{2(-3.6213)}{2(-3.6213)+3} - \frac{2(-3.6213)}{2(-3.6213)-3} \\ \frac{-7.2426}{-4.2426} - \frac{-7.2426}{-10.2426} =1.7071-0.7071=1
Therefore, the equation has no extraneous solution.

Does anyone know how to do this, I’m failing math and I need this to boost my grade. Someone help please
Nataly [62]

Answer:

Step-by-step explanation:

Hey, I'm not sure if I am right, but I hope it can create a spark or something.

8. Find x

10x - 1 = 14x - 37      Combine like terms

     +37        +37

10x + 36 = 14x          Combine like terms

-10x          -10x

    36 = 4x                Divide to isolate x

    <u>36</u> = <u>4x</u>

     4      4

    9 = x        

You can also do this method with the others.

PS: I am still not sure if this is the right method, lol. I just really want to help.
