Answer:

The answer is option A.

Step-by-step explanation:

If the report is made once a month, the daily variations (including the tendency to decrease efficiency on Friday) will be masked within the monthly result.

A sports magazine prints 12 issues per year, and a technology magazine prints 10 issues per year. The total number of pages in a

Evgesh-ka [11]

Answer:

$s=t-18...(1)$

$12*s=10*t+32...(2)$

Step-by-step explanation:

Let s be the number of pages in each issue of the sports magazine, and t be the number of pages in each issue of the technology magazine.

We have been given that Each issue of the sports magazine has 18 fewer pages than each issue of the technology magazine. We can represent this information in an equation as:

$s=t-18...(1)$

We are also given that sports magazine prints 12 issues per year, so the total number of pages in all the issues of sports magazine will be 12*s.

We are given that a technology magazine prints 10 issues per year, so the total number of pages in all the issues of technology magazine will be 10*s.

Further, the total number of pages in all the issues of the sports magazine for one year is 32 more than the total number of pages in all the issues of the technology magazine for one year.

We can represent this information in an equation as:

$12*s=10*t+32...(2)$

Therefore, our desired system of equations will be:

$s=t-18...(1)$

$12*s=10*t+32...(2)$

bogdanovich [222]

Answer:

Step-by-step explanation:

3a(a²-3a+4)-4(3a³-2a²) = 3a³ − 9a² + 12a − 12a³ + 8a²

= (3a³ − 12a³) + (− 9a² + 8a²) + 12a

= −9a³ − a² + 12a
