Fill in the missing term in the equation
Y_Kistochka [10]

Answer:

<u>x</u>

Step-by-step explanation:

Let's simplify the LHS so it can be equated to the RHS.

\frac{x}{x^{2} -4x+4} - \frac{x}{x^{2} -3x+2}

\frac{x}{(x-2)^{2} } - \frac{x}{(x-1)(x-2)}

\frac{x(x-1)-x(x-2)}{(x-2)^{2}(x-1)}

\frac{x^{2} -x-x^{2}+2x }{(x-2)^{2}(x-1)}

\frac{x}{(x-2)^{2}(x-1)}

Hence, the missing term in the numerator of the answer is <u>x</u>

Please answer 26 and 27 please thank you
ser-zykov [4K]

Answer:

Part 26) 3\frac{1}{4}\ in

Part 27) 2\frac{2}{3}\ cups

Step-by-step explanation:

Part 26)

we know that

The length of Alana's hair was 9 3/4 inches

After her haircut, the length was 6 1/2 inches

To find out how many inches did she have cut subtract 6 1/2 from 9 3/4

but first

Convert mixed number to an improper fraction

9\frac{3}{4}\ in=\frac{9*4+3}{4}=\frac{39}{4}\ in

6\frac{1}{2}\ in=\frac{6*2+1}{2}=\frac{13}{2}\ in

Find the difference

\frac{39}{4}-\frac{13}{2}=\frac{39-26}{4}=\frac{13}{4}\ in

Convert to mixed number

\frac{13}{4}\ in=\frac{12}{4}+\frac{1}{4}=3\frac{1}{4}\ in

Part 27)

we have that

Emeril used a total of 7 1/4 cups of flour to make three pastries

He used 2 1/4 cup of flour for the first and 2 1/3 cups of flour for the second

To find out how much cups of flour Emeril use for the third pastry, subtract the sum of the cups of flour used in the first and second pastry from the total cups of pastry used

Let

x ----> number of cups of flour used in the third pastry

x=7\frac{1}{4}-(2\frac{1}{4} +2\frac{1}{3})

but first

Convert mixed number to an improper fraction

7\frac{1}{4}\ in=\frac{7*4+1}{4}=\frac{29}{4}\ cups

2\frac{1}{4}\ in=\frac{2*4+1}{4}=\frac{9}{4}\ cups

2\frac{1}{3}\ in=\frac{2*3+1}{3}=\frac{7}{3}\ cups

substitute

x=\frac{29}{4}-(\frac{9}{4} +\frac{7}{3})

x=\frac{20}{4} -\frac{7}{3}

x=\frac{20*3-7*4}{12}

x=\frac{32}{12}\ cups

Simplify

x=\frac{8}{3}\ cups

Convert to mixed number

\frac{8}{3}=\frac{6}{3}+\frac{2}{3}=2\frac{2}{3}\ cups
