If 1 line completely overlaps the other line, they are the same line with infinite solutions.....so ur answer would be the 4th one
the answer should be 44. you plug in -7 for x.
11/12 hours left. 1 2/3 - 3/4 = 11/12. First, find the common denominator (12) . The problem is now 1 8/12 - 9/12. Use the 1 in (1 8/12) to borrow. Multiply the denominator by 1 (12) and add that to the numerator. The question is now 20/12 - 9/12. I assume that you can finish it off from there.
