Question

Ethan claims that StartAbsoluteValue 7 minus 3 EndAbsoluteValue = 4. Which statement about Ethan’s claim is true?

Ethan is correct because StartAbsoluteValue 7 EndAbsoluteValue = negative 7 and StartAbsoluteValue negative 3 EndAbsoluteValue = 3 so –7 + 3 = 4. Plot –7 on a number line, and move right 3 to get –4 on the line.
Ethan is incorrect because StartAbsoluteValue 7 EndAbsoluteValue = 7 and StartAbsoluteValue negative 3 EndAbsoluteValue = 3 so 7 + 3 = 10. Plot 7 on a number line, and move right 3 to get 10 on the line.
Ethan is incorrect because the absolute value bars are grouping symbols so first you must subtract. 7 minus 3 = 4, and StartAbsoluteValue 4 EndAbsoluteValue = negative 4.
Ethan is correct because the absolute value bars are grouping symbols so first you must subtract. 7 minus 3 = 4, and StartAbsoluteValue 4 EndAbsoluteValue = 4.

Answer 1

Ethan is correct because the absolute value bars are grouping symbols so first you must subtract. 7 minus 3 = 4, and StartAbsoluteValue 4 EndAbsoluteValue = 4. Therefore, Ethan's claim is true.
