Answer:
cesar is 11 1/4 years old
Step-by-step explanation:
k = kaleighs age
d = dwaynes age
3k - 2d = 5
d + k = 30
rewrite
-k -k
d = 30 - k
substitute
3k - 2(30 - k) = 5
3k - 60 + k = 5
4k - 60 = 5
+ 60 +60
4k = 65
/4 /4
k = 16.25
16.25 - 5 = 11.25 or 11 1/4
Y = -2x + 8
The slope of the perpendicular line will be: y = -1/2x + 5
