The rope is 3 yards.
1 yard = 3 feet, so 9 ÷ 3 = 3 yards.
I have a feeling its c but i might be wrong...
3(5b-1)=5
Get rid of the brackets
15b-3=5
add 3 to both sides of the equation
15b=8
divide both sides of the equation by 15
b=0.53
4(3y-1)=20
12y-4=20
12y=24
y=0.5
The answer is 18:24 because 9x2 is 18 & 12 x 2 is 24 so that’s the only one that makes any sense so yea!
