Consider the sum of 3/5 ± 3/4. Round each fraction and estimate the sum. Add the two fractions using a common denominator and then round the result. Which Estimate is the closest to the answer?

Acable company claims that the average household pays $78 a month for a basic cable plan, but it could differ by as much as $20. write an absolute value inequality to determine the range of basic cable plan costs with this cable company. a. |x − 78| ≥ 20 b. |x − 20| ≥ 78 c. |x − 20| ≤ 78 d. |x − 78| ≤ 20
