Vanyuwa [196]

Using proportions, it is found that $147.8 billion was spent on television advertising in the previous year.

  • $x, in billions, was spent on advertising expenditures on television last year.
  • This year, the amount declined 4.1%, hence it is 100% - 4.1% = 95.9% of last year's amount, that is, 0.959x.

This year spending's is of 141.7 billion, hence, the equation is:

0.959x = 141.7

x = \frac{141.7}{0.959}

x = 147.8

$147.8 billion was spent on television advertising in the previous year.

<h3>Answer:</h3>

room 3 or 4

<h3>Explanation:</h3>

We assume the inequalities tell the rooms that were checked and found empty.

The solution to 3) is ...

... 2x + 3 > 11

... 2x > 8 . . . . . subtract 3

... x > 4 . . . . . . .divide by 2

The solution to 4) is ...

... -3x > -9

... x < 3 . . . . . . divide by -3

Thus, rooms greater than 4 and less than 3 were found empty. Rooms 3 and 4 were not checked, so either one could hold Nessie.

_____

The other inequalities have solutions that are already covered by the solutions to these.

1) x < -1 . . . . after subtacting 4

2) x > 5 . . . . after multiplying by 5
