Answer:
least common multiple (LCM) of 9 and12 is 36
Answer:

Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal.
To determine the scale factor calculate the ratio of corresponding sides, that is
=
= 
Answer:
-2
Step-by-step explanation:
41 - 8m - 57 = 0
41- 8m = 57
-8m = 57-41
-8m = 16
m = -16/8
m = -2
Step-by-step explanation:
3x + 5y = 50
x + 5y = 31
use substitution
x = 31-5y
3(31-5y) +5y = 50
93 -15y + 5y = 50
93 - 10y = 50
--10y = -43
y = 43/10 = $4.30 for kids
now solve for x
x + 5(4.30) = 31
x + 21.5 = 31
x = $9.5 for adults
