In △ M N O , points R and T are the midpoints of their respective sides. MT and OR intersect at point C.

hichkok12 [17]

Answer:

3. 15 units

Step-by-step explanation:

When medians intersect, the point of intersection divides the median into parts in the ratio 2:1. That is ...

OC : CR = 2 : 1 = 4 units : 2 units . . . . . . OR = (4+2) units = 6 units

MC : CT = 2 : 1 = 6 units : 3 units . . . . . . MT = (6+3) units = 9 units

The sum of lengths OR + MT is ...

6 units + 9 units = 15 units

A mother is 30 years older than her son. Fifteen years ago the son was 1/3 of

nalin [4]

Let s be the son's age 15 yeasr ago and m the mother's age that year.

$s = \dfrac{m}{3}$

We also know that:

$m = s+30$

Plotting vallues:

$s = \dfrac{m}{3}\\\\\\3s = s+30\\\\2s = 30\\\\s = 15\\\\m = 45$

Remember that they were that age 15 years ago.

So their actual age is 30 and 60.
