Answer:
Willhelm was solving a problem in which we had to find the answer to 10(6) and then 15(4). This is why he counted 10 6 times, and then 15 4 times. I hope this helps :)
Answer:
x = 6
Step-by-step explanation:
AD is a midline segment and divides EB and EC in the same proportion, that is
= 
Substituting in values gives
=
=
( cross- multiply )
5x + 2 = 32 ( subtract 2 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6
2 + 17x - 5x + 9
First, subtract 17x - 5x to get 12x.
Second, leave the 12x be and add 2 + 9 to get 11.

Answer:
12x + 11
