How much did it cost summer to to buy 2.6 pounds of granola at the old price

coldgirl [10]

It was $6.00 per pound. So 2 pounds would be $12. But there is still that .6 of a pound left. If we know 1 pound costs $6, then we know 1/10th of a pound will cost $0.60. So 6 x .60 = 3.60. Add 12 and 3.60, and you get 15.60 for 2.6 pounds of granola at the old price.

What is the solution set of [1/x-2]<-2

BigorU [14]

Answer:

3/2 < x < 2

Step-by-step explanation:

We assume the problem is ...

[tek]\dfrac{1}{x-2}<-2[/tex]

This will not be true for x-2 > 0 because that would make the left side positive. So, we must have x < 2, which makes the denominator negative. Multiplying by (x-2), we get ...

1 > -2(x -2)

1 > -2x +4

2x > 3 . . . . . . add 2x-1

x > 3/2

From above, we also have x < 2, so the solution set is ...

3/2 < x < 2
