The length of a line segment is m. this segment is divided into: a) three equal parts; b) five equal parts. find the distance between the midpoints of the first and the last parts in each case. i need the correct answer tysm if you answer!

Consider the case where each part is of length 1. Then the midpoint of the first segment is at 1/2.

a) If there are 3 segments, the midpoint of the last segment is halfway between 2 and 3, at 2 1/2. The distance from the first midpoint to the last midpoint is ...

... 2 1/2 - 1/2 = 2 . . . . . that is, 2/3 of the total line length

When the line length is m, that is 2/3·m

b) If there are 5 segments, the midpoint of the last segment is halfway between 4 and 5, at 4 1/2. The distance from the first midpoint to the last midpoint is ...

... 4 1/2 - 1/2 = 4 . . . . . that is, 4/5 of the total line length

When the line length is m, that is 4/5·m

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
