Which values of a, b, and c correctly represent the answer in simplest form? 3 and one-half divided by 2 and one-fourth = a Star

sasho [114]

Answer:

(A) a=1,b=5,c=9

Step-by-step explanation:

We want to simplify $3\frac{1}{2} \div 2\frac{1}{4}$ for values of a, b and c which satisfies: $a\dfrac{b}{c}$

$3\dfrac{1}{2} \div 2\dfrac{1}{4}\\\text{Changing each fraction to improper fraction}\\=\dfrac{7}{2}\div \dfrac{9}{4}\\\text{Next, we change the division sign to multiplication by taking reciprocal of the second fraction}\\=\dfrac{7}{2}X \frac{4}{9}\\=\dfrac{7X4}{2X9}\\=\dfrac{28}{18}\\$ Converting our result to mixed fraction

$\dfrac{28}{18}=1\dfrac{10}{18}=1\dfrac{5}{9}\\a=1,b=5,c=9$

Z= -y + m/x Solve for x Please show work.

Fudgin [204]

Answer is a. You are trying to get x so that would be your answer “x=“ then you have Z and y left. This is still going to be a fraction since there is that line there still and won’t move. M is independent so that will be the denominator. You now have +y-z. This will then be on top and the reason why it’s on top is because most equations have the expression on top so it’s a numerator.
