Answer:

\frac{-x+5}{6x^2-x-12}}

Step-by-step explanation:

\frac{4x+5}{6x^2-x-12} - \frac{5x}{6x^2-x-12}

To subtract fractions the denomintors should be same

Here the denominator are same

so we combine the numerators and put denominator only once

\frac{4x+5-5x}{6x^2-x-12}}

Combine like terms

\frac{-x+5}{6x^2-x-12}}

Nelly works part-time in a shop to
zaharov [31]

Using proportions, Nelly's total pay for last week was of £220.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

From Monday to Friday, she worked 17 hours, hence:

  • For 15 hours, she was paid £8 per hour.
  • For the last 2 hours, she was paid £10 per hour.

On Saturday, she worked 5 hours, and was paid £16 per hour.

Hence her total payment is found as follows:

15 x 8 + 2 x 10 + 5 x 16 = £220.
