Answer:

|A - 8.7| < 0.4

Step-by-step explanation:

Given

8.5 < A < 8.9

Required

Write as an absolute value inequality

The absolute value inequality can be derived using

|A - Mid| < Length

First Step: Get the middle of the interval

Mid = \frac{1}{2}(8.5 + 8.9)

Mid = \frac{1}{2}(17.4)

Mid = 8.7

Next: Get the Length of the interval

Length = 8.9 - 8.5

Length = 0.4

Substitute values for Mid and Length in  |A - Mid| < Length

|A - 8.7| < 0.4

Hence:

<em>The absolute inequality is </em>|A - 8.7| < 0.4<em></em>

Answer:

1. >

2. <

3. =

Step-by-step explanation:

100x8=800, 4*7=28, multiplied by 25 is 700, therefore making 800 greater than 700. Whenever comparing two multiplication problems, multiplying large numbers produces large results, so whichever starts larger will have an end result that is larger. 100 was large and it is smaller to its counter 25.

36 elevens really means 11x36, which is 396. 40 elevens really means 40x11, which is 440 minus 11x3 which is 407. 407 is greater than 396. The same logic applies here as the previous answer, the only difference is that the removal of three elevens is still larger than 36 elevens in this case.

12x24=288, 6x24=144, doubled makes it 288. In this case, the six is half of the twelve to begin with and then is made up for later by the fact that it is doubled.

When I solve math questions like these, I ignore the fact that it doesn't want a mathematical answer, do the math anyway and pull logic from it. (If your teacher checks, do it on a separate piece of paper, and then toss it.)
