Answer:
the smaller is 25 and the bigger one is 30 .
Step-by-step explanation:
1.
x+y=55
y-5=x
------------
2.
x+y=55
y-x=5
2y = 60
y = 30
30 - 5 = 25
75 1/3 = 75.33
75.33% = 75.33/100
= 7533/10000
not sure if it can be simplified more than this
Since your slope is 3, (the number for slope is always right before x) and your y-intercept is one (that is always the number after the x) your answer would be B
