At 4pm the temperature started to change drastically. Each hour for three hours, the temperature decreases by 7 . Which expressi
Lyrx [107]
First off, because the temperature is decreasing, that means the final answer would be negative, or we can also say that there would be a -1 to be multiplied by the change. 

Each hour temperature changes by 7. The question also says that temperature keeps on changing for 3 hours. Therefore the temperature change would be by 3 7's, or 7+7+7.

Lastly, add the -1 from the beginning since it is a negative temperature change, the answer is (-1)(7+7+7)

genusus game cartridges are on sale at 15% off at L mart.Garney buys 2 of them priced at 44.99 and 49.99 rounded to the nearest
Verdich [7]

Answer:

We only need to calculate the 15% of 44.99 and 49.99 and sum them, for that, we have to multiply each number by 0.15:

44.99 * 0.15 + 49.99 * 0.15 = 14.27

He saved 14.25 (you should put the unit it's).

We could also have done a rule of three (which is what we have really did before)

44.99 - 100%

   x     -  15%

x = \frac{15*44.99}{100} =. 6.75

49.99 - 100%

    x     -  15%

x = \frac{15*49.99}{100} = 7.5

6.75 + 7.5 = 14.25
