Answer:
Step-by-step explanation:Let's solve your equation step-by-step.
(4564644)(4434688)=124x2
Step 1: Simplify both sides of the equation.
20242771971072=124x2
Step 2: Subtract 124x^2 from both sides.
20242771971072−124x2=124x2−124x2
−124x2+20242771971072=0
Step 3: Subtract 20242771971072 from both sides.
−124x2+20242771971072−20242771971072=0−20242771971072
−124x2=−20242771971072
Step 4: Divide both sides by -124.
−124x2
−124
=
−20242771971072
−124

Answer:
g = 14
Step-by-step explanation:
Using g = 14 we can do 14 x 3 to get 42. Then we can subtract 42 by 5 to get 37.
![\frac{ (\frac{2}{x} -1)}{ (\frac{1}{x} -1)}= \frac{( \frac{2-x}{x})}{( \frac{1-x}{x})} = \frac{2-x}{1-x}](https://tex.z-dn.net/?f=%5Cfrac%7B%20%28%5Cfrac%7B2%7D%7Bx%7D%20-1%29%7D%7B%20%28%5Cfrac%7B1%7D%7Bx%7D%20-1%29%7D%3D%20%5Cfrac%7B%28%20%5Cfrac%7B2-x%7D%7Bx%7D%29%7D%7B%28%20%5Cfrac%7B1-x%7D%7Bx%7D%29%7D%20%3D%20%5Cfrac%7B2-x%7D%7B1-x%7D%20)
. Now the answers on your paper do not have this choice, but if you think about it, (2-x)=-1(x-2) and (1-x)=-1(x-1). This means that when you have (2-x)/(1-x), this also equals to (x-2)/(x-1), since the -1's cancel out. So, the answer is D.
I hope this was helpful!
