6-5 solving rational equations 8/x+3=1/x+1
AfilCa [17]

Answer:

x = -5/7

Step-by-step explanation:

8/(x+3)=1/(x+1)

Using cross products

8*(x+1) = 1*(x+3)

Distribute

8x+8 = x+3

Subtract x from each side

8x-x +8 = x+3-x

7x +8 =3

Subtract 8 from each side

7x+8-8 = 3-8

7x = -5

Divide by 7

7x/7 = -5/7

x = -5/7

Add and simplify
Tanya [424]

Answer:

Your 1st answer is correct

Step-by-step explanation:

\frac{1}{(x - 1)}  -  \frac{3}{(1 - x)}   + 2

\frac{1}{(x - 1)}  -  \frac{3}{ - (x - 1)}  + 2

\frac{1}{(x - 1)}   +  \frac{3}{(x - 1)}  + 2

\frac{4}{(x - 1)}  + 2

\frac{4 + 2(x - 1)}{x - 1}

\frac{4 + 2x - 2}{x - 1}

= \frac{2x  + 2}{x - 1}

=  \frac{2(x + 1)}{x - 1}

Sarah needs to have a plumber come to her house and fix a leaky faucet in her bathroom. The plumber charges $50 to come to her h
klio [65]

Answer:

Sarah can have the plumber work on her faucet for six (6) hours maximum

Step-by-step explanation:

Hi

As Sarah has only $234.50 in her savings and the plumber charges $50 just to come to her home, so left-over $184.50 of her saving for pay work hours.

Then as the plumber charges $30.75 per hour we have that \frac{\$ 184.50}{\$ 30.75/h}=6h is the maximum amount of hours that Sarah can have the plumber work on her faucet.
