Answer is b, hope you pass
Answer:
B) T = 2πr/v
Step-by-step explanation:
To solve the given equation for T, multiply it by T/v.

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
L = A/W
Length equals area divided by width
