Using improper fractions, it is found that they broke the record and were 0.8 minutes faster.

<h3>How to convert improper fractions to standard fractions?</h3>

The conversion is made according to the following formula:

a\frac{b}{c} = a + \frac{b}{c} = \frac{ac + b}{c}

In this problem, the time had to be faster than 12\frac{2}{5} minutes, which is a time in minutes of:

12\frac{2}{5} = 12 + \frac{2}{5} = 12 + 0.4 = 12.4

Researching the problem on the internet, it is found that their time was of 11\frac{3}{5} minutes, hence:

11 + \frac{3}{5} = 11 + \frac{3}{5} = 11 + 0.6 = 11.6

11.6 < 12.4, hence they broke the record.

12.4 - 11.6 = 0.8, hence they were 0.8 minutes faster.

Rearrange the equation so xxx is the independent variable. Pls Help :)<br><br>−5x−4y=−8
S_A_V [24]

The rearranged expression will be equal to y = (-5/4)x + 2.

<h3>What is an expression?</h3>

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

<h3 />

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

The given expression will be rearranged as below:-

−5x−4y=−8

Solve the above expression for the value of y and the x variable will become independent.

−5x−4y=−8

Take -5x to the right side of the equation.

-4y = 5x - 8

Divide the equation by -4.

y = ( -5 / 4 )x + 2

Therefore, the rearranged expression will be equal to y = (-5/4)x + 2.
