$11.\\2p+5r=q\ \ \ \ |subtract\ 5r\ from\ both\ sides\\\\2p=q-5r\ \ \ \ |divide\ both\ sides\ by\ 2\\\\\boxed{p=\dfrac{q-5r}{2}}$

$17.\\\dfrac{2}{5}(z+1)=y\ \ \ \ |multiply\ both\ sides\ by\ \dfrac{5}{2}\\\\z+1=\dfrac{5}{2}y\ \ \ \ |subtract\ 1\ from\ both\ sides\\\\\boxed{z=\frac{5}{2}y-1}$

The circular mirror hanging on Belle's wall has a diameter of 18 inches. What is the

just olya [345]

Answer:

56.52 inches

Step-by-step explanation:

The circumference of a circle can be found using:

$c=\pi d$

We know the diameter is 18, and $\pi$ is being rounded to 3.14, so we can substitute them in.

c=3.14*18 <em>Multiply</em>

c=56.52

So, the circumference is 56.52 inches

What is the system of inequalities associated with the following graph?

slamgirl [31]

One line passes through the points (-2,3) and (0,-3) , it means the y intercept is b=-3

and slope m = $\frac{(-3-3)}{0-(-2)}$

$= \frac{-6}{2}= -3$

So the equation of line will be $y= -3x -3$

And the inequality should be $y\geq -3x-3$

Or $3x +y \geq -3$

And the other line passes through (-2,3) and (0,2)

So the y intercept is b=2

and the slope is $m= \frac{2-3}{0-(-2)} = \frac{-1}{2}$

So the equation of line will be $y= \frac{-1}{2} x +2\\and the inequality should be y \leq \frac{-1}{2} x+2$

$2y +x \leq 4$

So answer is $3x +y \geq -3, x+2y\leq 4$
