200% pf 50 is 100 and 120% of 50 is 60
so 150 - 110= 40

5.27 repeating as a mixed number in simplest form

charle [14.2K]

Hey there! I'm happy to help!

Let's call our fraction x.

x=5.2727272727......

We want to get rid of the repeating decimals. If we multiply our fraction by 100, we have that 100x=527.27272727.....

100x=527.2727272727....

x=5.27272727....

If we subtract these equations, the repeating stuff will be gone and we can solve for x.

99x=522

We divide both sides by 99.

x=522/99= 58/11= 5 3/11.

Have a wonderful day! :D

Write an equation in slope-intercept form for the line that has the given slope and contains the point. Please show some work.(

Paha777 [63]

Answer:

An equation in the slope-intercept form will be:

$y=-\frac{1}{2}x+0$

Step-by-step explanation:

Given the points

(4, -2)

(2, -1)

Finding the slope between the points

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(4,\:-2\right),\:\left(x_2,\:y_2\right)=\left(2,\:-1\right)$

$m=-\frac{1}{2}$

We know that the slope-intercept form of the line equation is

$y=mx+b$

where m is the slope and b is the y-intercept.

substituting the values m=-1/2 and the point (4, -2) to determine the y-intercept i.e. 'b'.

$y=mx+b$

$-2=-\frac{1}{2}\left(4\right)+b$

$\frac{1}{2}\cdot \:4+b=-2$

$-2+b=-2$

$b=0$

Now, substituting the values b=0 and m=-1/2 to determine the equation in the slope-intercept form.

$y=mx+b$

$y=-\frac{1}{2}x+0$

Thus, an equation in the slope-intercept form will be:

$y=-\frac{1}{2}x+0$
