In algebra, the conversion of a more complex number to a simpler mixed number is rather simple. For the repeated numbers, which are designated by the bar above them, we simply have to put over 9 for each number repeated and 0 for the non-repeated numbers.
In this item, we have 1.28 with bar above 28 signifying that the number can also be written as 1.28282828.... The mixed number is then equal to, <em>1 and 28/99 or 1 and 28 over 99</em>
Therefore, the answer to this item is the second choice.
It is nonequivalent. Figure it out this way. Think about what number has to be multiplied by both the numerator and the denominator of to get to . It has to be the samee number for the one expression to be equivalent to the other. To get from 5x to x^3, we have to multiply by 1/5x^2. When we do that we get x^3. Good. Now we have to multiply the denominator by the same thing, 1/5x^2. . As you can see, they are not equivalent.
G = x Felicia is Gabriella's age + 6 F = x + 6 Their mother is twice Felicia's age M = 2(x + 6) or 2x + 12 Tanya is the age of their mother plus Gabriella's age A = 2x + 12 + x = 3x + 12 3x + 12
