3 0

Answer:

The bookstore has 48 left.

Explanation:

If yesterday the bookstore solve 1/4 of 80 magazines then it sold:

\frac{1}{4} X 80 →  \frac{80}{4}[/tex} →  20

So at the end of the day it had  80-20 magazines left or 60 total magazines left.

Today it sold 185 of 60 (the total left from yesterday) or:
[tex]\frac{1}{5} X 60  →  \frac{60}{5} → 12

So, at the end of today it had  

60-12

magazines left or 48 total magazines left.

Consider the Inequalities X >7 and X < 12 select all the values that satisfy both Inequalities
Maksim231197 [3]

Answer:

9;10

Step-by-step explanation:

What we can first do is make them into one double sided inequality and then interpret it from there.

After combining them we get: 7<x<12

This means that any number between 7 and 12 can be picked.

Keep in mind, this means that 7 and 12 cannot be picked, they have to be in between.

Therefore, we get our aswers of 9 and 10!

3y – 6x = 3 y = 2x + 1
Keith_Richards [23]

Answer:

infinite solutions along the line y = 2x+1

Step-by-step explanation:

3y – 6x = 3

y = 2x + 1

Replace y in the first equation with the second equation

3 ( 2x+1) -6x =3

6x +3 -6x = 3

3=3

This is always true so there are infinite solutions along the line y = 2x+1
