I'm not sure about the formula.
But since 38/2=19
19-2=17
Linda is 17 years old.
a possible formula could be:
L=38/2-2
A compound inequality for the graph would be:
x >= 0 and x < 2
So the ratio is 3:5. Se need to find x:1 you do that by dividing each side by 5. 3/5 = .6
36. If 7/11 did bring one, then 4/11 didn't. 4*9=36
So a²+b²=c²
8²+15²=c²
64+225=c²
289=c²
±17=c
So c=17 or c=-17
