Answer:

x = -16/-30 or x = .54

Step-by-step explanation:

-4(6x - 7) - 3(4 + 2x)

-24x + 28 - 12 - 6x

combine like terms

-30x + 16

subtract 16 from both sides

-30x = -16

divide by -30

x = -16/-30 0r x = .54

kondaur [170]

It will take them 80 days to sprint 20 miles.

The method that can be used in solving this type of question involves the use of equating fractions together with their arithmetic operation.

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

A fraction usually consists of two terms with a term located in the upper part called the numerator and another term located in the lower part called the denominator.

From the parameters given:

  • The track team has a plan to sprint 20 miles this school year.
  • If the runners participating in the event sprint 1/4 miles in each day.

Then, the estimate of the number of days it will take them to sprint 20 miles can be computed as:

\mathbf{= \dfrac{20 \ miles }{\dfrac{1}{4} \ miles/ day}}

\mathbf{= 20 miles  \times \dfrac{4}{1} \ day/miles}

= 80 days
