Consider the expressions separately:

\frac{35}{25-5*4}= \frac{35}{25-20}=\frac{35}{5}=7

\frac{225}{( 5*6-5 )( \frac{729}{81} )}=  \frac{225}{( 30-5 )( 9 )}= \frac{225}{( 25 )( 9 )}= \frac{9}{9}=1

So:\frac{35}{25-5*4}-\frac{225}{( 5*6-5 )( \frac{729}{81} )}=1-7=-6

Mr. Jackson sold 3 computer monitors in the first year. In the second year, he sold 4 times as many monitors as in the first yea
GenaCL600 [577]

Answer:

There wasn't really a question here but for both the answers is

for year 2 we got 12 sales

for year 3 we got 18 sales

Step-by-step explanation:

since the first year Mr.Jackson sold 3 computer monitors then in the second year he must've multiplied the times he had sold it which means 4 x 3 which equals 12

as well as the third year, on the third year he sold 6 times the first year so it means 6 x 3 which equals 18
