Maslowich

Answer:

180 min

Step-by-step explanation:

The first thing is to get the number of days in two weeks that he would read the book, since he only does it when he goes to school. School goes from Monday to Friday, that is to say 5 days, how two is two weeks would be a total of 10 days. Mathematically, it would be the equation, where X would be the number of minutes inside the parentheses and the minutes read before and after school:

X = 10 * (10 + 8)

Solving:

X = 180

In other words, in two weeks he has read a total of 180 minutes.

1) Last Tuesday, Regal Cinemas sold a total of 85 movie tickets. Ticket sales totaled
irakobra [83]

In this question, some of the data is missing so its a complete question and the solution can be defined as follows:

\bold{\text{m = matinee tickets}} \\\\\bold{\text{s = student tickets}}\\\\\bold{\text{r = regular tickets}}

By given question, calculating equations are:

\to \bold{m + s + r = 8500}............................................(a)\\\\\to \bold{5m + 6s + 8.50r = 64600}............................(b)\\\\\to \bold{s = 2m}...................(c)

Putting the equation (c) value in the equation (a) to calculate value:

m + 2m + r = 8500\\\\3m + r = 8500\\\\r = 8500 - 3m........................................(d)

Putting equation (c) and (d) value into equation (b):

5m + 6(2m) + 8.50(8500 - 3m) = 64600\\\\5m + 12m + 72250 - 25.50m = 64600\\\\-8.50m = 64600 - 72250 \\\\-8.50m = -7650\\\\m = \frac{-7650}{-8.50}\\\\m = \frac{7650}{8.50}\\\\m = 900

Putting m value into equation (c) and equation (d) to calculate its value:

Calculating the s value:

\to s = 2(900) \\\\ \to s = 1800

Calculating the r value:

\to r = 8500 - 3(900) \\\\\to r = 8500 - 2700\\\\\to r = 5800\\\\

So, the final value of "m, s, and r" are "900, 1800, and 5800".
