What does that even mean you need a picture to really understand
4:7
7-4=3
if al has 60 more than ruth
60=3 units
divide by 3
20=1unit
20 times 4=80
20*7=140
so ruth:alison=80:140
alisonn gave 35 to ruth
80+35=115
140-35=105
so ruth:alson=115:105=23:21
new ratio is 23:21

Answer:
x = 12
Step-by-step explanation:
The two angles are complementary since they form a 90 degree angle.
35+ 4x+7 = 90
Combine like terms
42 +4x = 90
Subtract 42 from each side
42-42 +4x =90-42
4x = 48
Divide each side by 4
4x/4 = 48/4
x = 12
