By definition of absolute value we have two equalities:
2x + 1 = 10
2x + 1 = -10
For 2x + 1 = 10:
2x + 1 = 10
2x = 10-1
2x = 9
x = 9/2
For 2x + 1 = -10:
2x + 1 = -10
2x = -10-1
2x = -11
x = -11 / 2
Answer:
{-11/2, 9/2}
Lance is not correct. Although his number does have more decimal places, his number is not greater. Angel has the greatest number in the most valued place, which is the tenths place in this case. We can understand this by knowing that 5>4. So, Angel has more water, and Lance is incorrect.
