Mark has been watching 16 movies for the past x months. max has been trying to keep up with his pace but has only been able to watch half as many as mark has. between the two of them, they have watched a total of 144 movies. for how many months have they been watching 144 movies? a. 3 b. 4 c. 5 d. 6

Mark = 16

Max = 8

16 + 8 = 24

144/24 = 6

Option D. 6 months

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
