Perform the following operations and prove closure. Show your work.<br><br> (x/x+3) + (x+2/x+5)

Westkost [7]

Answer:

$\frac{2(x^{2} + 5x + 3)}{(x+3)(x+5)}$

Step-by-step explanation:

We need to sum the following two expressions:

$\frac{x}{x+3} + \frac{x+2}{x+5}$

$\frac{x(x+5) + (x+2)(x+3)}{(x+3)(x+5)}$

expanding the polynomial in the numerator:

$\frac{2x^{2} + 10x + 6}{(x+3)(x+5)}$

$\frac{2(x^{2} + 5x + 3)}{(x+3)(x+5)}$

This is the most simplified form we can get:

$\frac{2(x^{2} + 5x + 3)}{(x+3)(x+5)}$

Paisley has 8\tfrac{1}{4}8 4 1 cups of yogurt to make smoothies. Each smoothie uses \tfrac{11}{16} 16 11 cup of yogurt. How

Ivenika [448]

Given:

Total Yogurt = $8\dfrac{1}{4}$ cups

Yogurt required for each smoothie = $\dfrac{11}{16}$ cup

To find:

The number of smoothies that Paisley can make with the yogurt.

Solution:

We know that,

$\text{Number of smoothies}=\dfrac{\text{Total yogurt}}{\text{Yogurt required for each smoothie}}$

Substituting the given values, we get

$\text{Number of smoothies}=\dfrac{8\dfrac{1}{4}}{\dfrac{11}{16}}$

$\text{Number of smoothies}=8\dfrac{1}{4}\times \dfrac{16}{11}$

$\text{Number of smoothies}=\dfrac{32+1}{4}\times \dfrac{16}{11}$

$\text{Number of smoothies}=\dfrac{33}{4}\times \dfrac{16}{11}$

$\text{Number of smoothies}=3\times 4$

$\text{Number of smoothies}=12$

Therefore, the number of smoothies is 12.

12 is 25% of what number using a ratio table

Contact [7]

% means 'parts out of 100' so
25%=25/100

is 12 is 25 parts out of 100 of a number
so 12=(25/100)x
25/100 simplifies to 1/4
or if 12=(1/4)x
we multiply both sides by 4 and get
48=1x
