What is the solution to the inequality -6+|2p+3|&gt;7
andrezito [222]

Answer:

p >5                  or                            p <-8

Step-by-step explanation:

-6+|2p+3|>7

Add 6 to each side

-6+6+|2p+3|>7+6

|2p+3|>13

We get a positive and negative solution

2p +3 > 13             and  2p +3 < -13

Subtract 3 from each side

2p +3 -3> 13-3           or 2p +3-3 < -13-3

2p > 10                                      2p < -16

Divide by 2

2p/2 > 10/2                                2p/2 <-16/2

p >5                  or                            p <-8

David's optometrist sold him a bottle of eyeglass cleaner containing 30 ml of glasscleaning solution. assuming there are 20 drop
Furkat [3]
Each complete cleaning requires 6 drops of cleaner.  Let's convert that to ml:

6 drops     1 ml              3 ml cleaner
----------- * ------------- = ------------------- = 0.3 ml cleaner per cleaning
                 20 drops      10 cleanings

Recall that 1 bottle contains 30 ml cleaning fluid.

How many cleanings is one bottle of fluid good for?

1 bottle       0.3 ml
----------- = -----------   => x = 100 cleanings/bottle
      x            30 ml
