Answer:
A.4/7
Step-by-step explanation:
P(A/B) =P(AnB) /P(B)
=1/6/7/24
=1/6×24/7
=4/7
Answer:
x = -5/7
Step-by-step explanation:
8/(x+3)=1/(x+1)
Using cross products
8*(x+1) = 1*(x+3)
Distribute
8x+8 = x+3
Subtract x from each side
8x-x +8 = x+3-x
7x +8 =3
Subtract 8 from each side
7x+8-8 = 3-8
7x = -5
Divide by 7
7x/7 = -5/7
x = -5/7
C, always go with supervisors
Answer:
x = - 6
Step-by-step explanation:
Given
x² = 24 ( multiply both sides by 3 )
2x² = 72 ( divide both sides by 2 )
x² = 36 ( take the square root of both sides )
x = ±
← note plus or minus
x = ± 6
solutions are x = - 6, x = + 6
The smallest solution is x = - 6
