Which represents the solution to the absolute value equation? 3|2x+4|-1=11

Mathematics

The first step for absolute value equations is to isolate the expression contained within the absolute value bars:

3|2x+4|-1 = 11
3|2x+4| = 12
|2x+4| = 4

so |2x+4| is 4 units away from 0 on a number line, but we don't know in which direction -- negative or positive? you'll have two answers.

2x+4 = 4

AND

2x+4 = -4

solve both of those two step equations and you'll get

x = 0

AND

x = -4

so 0 and -4 are your solutions.

You work in a chemical lab. Last quarter, you successfully completed an average of about 5 chemical analyses per day. This quart
Kryger [21]

Answer: 60%

Step-by-step explanation:

Since, According to the question,  Last quarter, we successfully completed an average of about 5 chemical analyses per day.

Therefore initially our average = 5 chemical analyses per day.

Again, From the question, This quarter, we have increased this average to about 8 per day.

Therefore New average =chemical analyses 8 per day

Thus, Percentage change in the average = (Initial average - New average)×100/ initial average  

= \frac{8-5}{5} \times 100

= \frac{3}{5} \times 100

= 60 %

Therefore, Percentage change in the average=60 %
