A yoga studio offered a special for high school students where new students could join for half off of the monthly fee (includes

Eva8 [605]

Given:

the discounted price was offered by the yoga studio at 50% off the regular price 'r' (monthly fee).
the one-time processing fee is $8.25
10 students took this offer and the yoga studio collected $392.50

To Find:

The regular price of the monthly fee 'r'

Solution:

The equation can be framed as

$(r-\frac{50}{100}.r)+8.25=39.25\\\frac{50}{100}.r+8.25=39.25\\\frac{r}{2}+8.25=39.25\\\frac{r}{2}=31\\r=(31)(2)=62$

And, the regular price of the monthly fee is $62.

Calculation:

We know that 10 students took the offer and the yoga studio collected $392.50. This means, using the Unitary Method, the studio has collected $(392.50/10) = $39.25 per student.

Now, if r denotes the regular price of the monthly fee, the offer runs a 50% discount on r.

So, the discounted price should be $(r - 50% of r) i.e., $r-\frac{50}{100}.r$

We must add to this the one time processing fee of $8.25

Therefore, the total price paid by one student would be

$(r-\frac{50}{100}.r)+8.25$

This must be equal to $39.25 as we have calculated this to be the amount collected by the yoga studio per person.

So, the equation can be framed as

$(r-\frac{50}{100}.r)+8.25=39.25\\\frac{50}{100}.r+8.25=39.25\\\frac{r}{2}+8.25=39.25\\\frac{r}{2}=31\\r=(31)(2)=62$

Thus, the regular price of the monthly fee is $62.

Please help. Find the value of x

S_A_V [24]

It’s 130°, because 50+50=100 and 2x is equal to the same angel on the direct opposite side so work where you have 50. then the 4 angles should add to 360° and 360-100= 260, then you have to divide 260 by 2 because it has to be equal to both side so then 260/2=130° and to know that it’s correct add 130+130+50+50 and you get 360°!

Check all that apply

adell [148]

So we would want to isolate x. Start by multiplying both sides by -3. Since we are multiplying negative number, we flip the sign.

So that would be x ≥12. That means x should be greater than or equal to 12.

So now it's easy to answer.

C, D, E would be the answer.

find the equation in slope intercept form of a line that is a perpendicular bisector of segment AB with endpoints A(-5,5) and B(

aliina [53]

The equation in slope intercept form of a line that is a perpendicular bisector of segment AB with endpoints A(-5,5) and B(3,-3) is y = x + 2

<h3>Solution:</h3>

Given, two points are A(-5, 5) and B(3, -3)

We have to find the perpendicular bisector of segment AB.

Now, we know that perpendicular bisector passes through the midpoint of segment.

The formula for midpoint is:

$\text { midpoint }=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)$
