Repeated fractions are written with 9's in the denominator.
0.136 = 136/1000
0.136 repeated = 136/999
(y^2-y-12)/(y^2-2y-15) factor both the numerator and denominator...
(y^2-4y+3y-12)/(y^2-5y+3y-15)
(y(y-4)+3(y-4))/(y(y-5)+3(y-5))
((y-4)(y+3))/((y-5)(y+3)) so the (y+3) terms cancel leaving
(y-4)/(y-5)
Answer:
A.
Step-by-step explanation:
The answer would be a because if you have s + 11 you will get 23
but if you were to find s it would be 12
12.4%x = 7.13
Simplify both sides of the equation.
0.124x=7.13
Divide both sides by 0.124.
0.124x / 0.124 = 7.13 / 0.124
x=57.5
