Answer:

C. $\frac{27}{225}=\frac{b}{100}$

Step-by-step explanation:

To find the number of black ribbons one would have subtract the amount of red ribbons from the total number of ribbons. Then one would have to express it as a proportion. Part over whole equals percent over 100. The number of black ribbons over total ribbons equals "b" over 100.

Step-by-step explanation:

$(x^2+9x+10)(x-2)= \\\\x^3-2x^2+9x^2-18x+10x-20= \\\\x^3+7x^2-8x-20$

Jimmy is incorrect.

Using long division, you can find that the real answer.

First, subtract $x^2(x-2)$ from the original expression, leaving you with $9x^2+2x-40$ .

Next, subtract $9x(x-2)$ from the expression, leaving you with $20x-40$ . Finally, subtract $20(x-2)$ from the expression, leaving you with a remainder of 0. This means that the real quotient is $x^2+9x+20$ . Hope this helps!
