Answer:
a and c I think if I'm wrong I will try again
1)v/4-3=5
v-12=20
v=32
2)u/5+3=1
u+15=5
u=-10
3)6+z/9=9
54+z=81
z=27
4)-7+f/2=-1
-14+f=-2
f=12
5)9+w/4=-5
36+w=-20
w=-56
6)e/7-3=-5
e-21=-35
e=-14
7)-8+d/5=2
-40+d=10
d=50
8)u/5+3=6
u+15=30
u=15
9)f/-3+5=8
f-15=-24
f=-9
Answer:
10:12:15
Step-by-step explanation:
a/b=5/6
b/c=4/5
thus
c/b=5/4
LCM of 4 and 6=12
5/6=10/12
5/4=15/12
b is the 12 in both
thus ratio between a:b:c is 10:12:15
