68 = 7b - 9 -7b = -68-9 b = (-68-9)/-7 = 11
I would say that the answer is 23. a=23b=34c=12 a=12 so b=12/23 = 0.52173913 so a/b =12/(12/23) =23
12
B=61
The simplest way: Ratio a : b equals ratio c : d if (and only if) a*d = b*c
68 = 7b - 9 -7b = -68-9 b = (-68-9)/-7 = 11
A:B = 3:4 = 9:12 B:C = 6:5 = 12:10 So A:B:C = 9:12:10
I would say that the answer is 23. a=23b=34c=12 a=12 so b=12/23 = 0.52173913 so a/b =12/(12/23) =23
B=61
12
b = 12 12(3)+3 = 39, use a calculator to find out
The simplest way: Ratio a : b equals ratio c : d if (and only if) a*d = b*c
Z if d is equally to f plus10
-24
a varies directly as b and a = 12 when b = 4. What is the constant of variation?
Gh
b= 4
