Question

A meteorologist reported yesterday's high and low temperatures were within 7 degrees of the average temperature of sixty degrees for the day. Write an absolute value inequality that models the range of temperatures for the day.
The ideal weight of a nickel is .17637 ounce. A bank teller weighs a roll of nickles to ensure there are 40 in the roll. Write an inequality that BEST describes the allowance for an margin of error of .015 of an ounce in the total weight (W) of the roll. The weight of the wrapper is not part of the problem.

W≤7.0698W≤7.0698

7.0398≤W≤7.06987.0398≤W≤7.0698

.16137≤W≤.19137.16137≤W≤.19137

7.0398≤W




Choose the inequality that BEST illustrates the following condition: All real numbers X with and absolute value of greater than three

|X|≤3

|X|≥3

|X|<3

|X|>3

Answer 1

The absolute value inequality is
| x - 7 | ≥ 60

The inequality that describes the weight of the coins is
7.0398 ≤ W ≤ 7.06987

The inequality that corresponds to the given statement is
| X | > 3
