Given: X = r + 2, Y = 2r - 9, and Z = r 2 + 17r + 30. Simplify [X · Y - Z] ÷ X.

musickatia [10]

Answer: r - 24

Step-by-step explanation:

$X=r+2;Y=2r-9;Z=r^2+17x+30$

$\frac{x*y-z}{x}$

$\frac{[(r+2)(2r-9)]-(r^2+17r+30)}{r+2}$

$\frac{(2r^2-9r+4r-18)-(r^2+17r+30)}{r+2}$

$\frac{(2r^2-5r-18)-(r^2+17r+30)}{r+2}$

$\frac{2r^2-5r-18-r^2-17r-30)}{r+2}$

Combine like terms;

$\frac{r^2-22r-48}{r+2}$

Solve the quadratic equation;

$\frac{(r-24)(r+2)}{r+2}$

Simplify;

$r-24$

On a city map 3/4 inch corresponds to 7 1/2 miles bonnie drives from her house to a movie theater and then from a movie theater

Juliette [100K]

Answer:

Option D: $12\frac{1}{2}$ is the correct answer.

Step-by-step explanation:

Given that:

3/4 inches on map are equal to $7\frac{1}{2}$ miles

We will find the unit rate in term of inches.

$\frac{3}{4}\ inches = 7\frac{1}{2}\\\\Unit\ rate = \frac{15}{2}*\frac{4}{3}\ miles\\\\Unit\ rate = 10\ miles\ per\ inch$

Total distance covered by Bonnie according to map;

Total distance = $\frac{1}{2}+\frac{3}{4} = \frac{2+3}{4}$

Total distance = $\frac{5}{4}\ miles$

Actual distance = $\frac{5}{4}*10 = \frac{25}{2}\ miles \\$

Actual distance = $12\frac{1}{2}\ miles$

Hence,

Option D: $12\frac{1}{2}$ is the correct answer.
