Answer:

$\frac{x^2+4x-1}{x(x+2)}$

Step-by-step explanation:

Given

$\frac{x+5}{x+2}$ - $\frac{x+1}{x^2+2x}$ ← factor denominator

= $\frac{x+5}{x+2}$ - $\frac{x+1}{x(x+2)}$

We require the fractions to have a common denominator.

Multiply numerator/denominator of first fraction by x

= $\frac{x(x+5)}{x(x+2)}$ - $\frac{x+1}{x(x+2)}$

Subtract terms on numerator leaving the common denominator

= $\frac{x^2+5x-x-1}{x(x+2)}$

= $\frac{x^2+4x-1}{x(x+2)}$

To make a certain shade of orange calvin uses a rate of 2 ounces of yellow paint to 5 ounces of red paint if he uses 200 ounces

ycow [4]

Answer: 80 ounces of yellow paint

Working:
As we know 2 ounces of yellow paint to 5 ounces of red paint, we can make a ratio:

2:5

Then we look at the question which says 200 ounces of red paint, so we replace the 5 ounces of red paint in the ratio with 200.

2:200

Then we figure out how much the 5 has been multiplied by to get to 200. We do this by doing

200 divide 5 = 40

Therefore we times the 2 ounces of yellow paint by 40 which gets us:

80:200

We can think of it as a fraction too to confirm our answer:

Simplify 80 / 200

We get 2 / 5.
