M is between L and N. If LN = 91 and LM = 23, find MN.
Tasya [4]

Answer:

MN = 68

Step-by-step explanation:

LN = 91

LM = 23

Points L, M, and N are collinear, therefore, according to the segment addition postulate, the following can be deduced:

LM + MN = LN

23 + MN = 91 (Substitution)

Subtract 23 from both sides

23 + MN - 23 = 91 - 23

MN = 68

umka21 [38]

Answer:

Accrued expenses are those liabilities that have built up over time and are due to be paid. Accrued expenses are considered to be current liabilities because the payment is usually due within one year of the date of the transaction. Accounts payable are current liabilities that will be paid in the near future.

Using this diagram, select the pair of lines that must be parallel.
Bas_tet [7]

Answer:

The answer would be D: d || f.

Step-by-step explanation:

  1. Since the angles 4 and 7 are parallel, it would make sense for the lines that the angles are on to be parallel as well.
  2. It just so happens that line d and line f are completely parallel to each other and angles 4 and 7 are on the lines. So the answer would be D.
