14/10 = 1.4 (10 %)
1.4/2= 0.7 (5%)
1.4 + 0.7 = 2.1 (15%)
14 - 2.1 = $11.9
Answer:The answer is 3 & 7
Step-by-step explanation:3 x 7 = 21
3 + (7) = 10
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 10x + 21 = 0
If so, the solution to factor the quadratic equation above is:
(X + 3 ) (X + 7)
To summarize, since 3 and 7 multiply to 21 and add up 10, you know that the following is true:
x2 + 10x + 21 = (X + 3 ) (X + 7)

Answer:
C. 
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.
1/5 of 3/5=1/5 times 3/5=3/25
