Answer:

The value of $x=8$ .

Step-by-step explanation:

Given:

$\frac{x+3}{x}-\frac{x+1}{x+4}=\frac{5}{x}$

We need to solve this equation.

Solution:

First combining equation having same denominators we get;

$\frac{x+3}{x}-\frac{5}{x}=\frac{x+1}{x+4}$

Now denominators are common so we will solve the numerators we get;

$\frac{x+3-5}{x}=\frac{x+1}{x+4}\\\\\frac{x-2}{x}=\frac{x+1}{x+4}$

Now by cross multiplication we get;

$(x-2)(x+4)=x(x+1)$

Now Applying distributive property we get;

$x^2+4x-2x-8=x^2+x\\\\x^2+2x-8=x^2+x$

Now Combining the like terms we get;

$x^2+2x-x^2-x=8\\\\x=8$

Hence on solving we get the value of $x=8$ .

You have worked as a guide at the aquarium for two summers. This summer you have been offered the job again, but with a 4 percen

olga nikolaevna [1]

Answer:

More earn this summer per month = $30 more

Entire summer earning (for 2.5 months) = $1950

Step-by-step explanation:

For 2.5 months, you got 1875 dollars, so per month salary is:

1875/2.5 = $750 per month

This summer, you got a 4% raise, that means:

4% = 4/100 = 0.04

The raise is:

0.04 * 750 = $30 raise

So, new monthly salary is:

750 + 30 = $780

So, assuming you will work 2.5 months again this summer, you total earnings would be:

2.5 * 780 = $1950
