No, because u add 9 to both sides to leave what's in the absolute value brackets alone so u get l3x+8l=4.Since the sum is positive then it has a solution.
| 3x + 8 | - 9 = -5....u have to get the absolute value (and everything in it) on one side of the equal sign, and everything else on the other side. So we have to get that -9 across the equal sign by adding 9 to both sides | 3x + 8 } = -5 + 9 | 3x + 8 | = 4...so that number is not negative anymore now u can set up ur 2 equations and solve for x...ur 2 equations would be: 3x + 8 = 4 and 3x + 8 = -4...so there will be 2 solutions
** if that -9 would not have been there, then ur friend would have been correct
Each one would be 5 minutes because 2 1/2 Times 4 = 10 minutes. You would have 20 minutes remaining so divide 20 by how many segments there are, which is 4 to get 5
