You are correct!
90 would be the correct choice, here is why:
use the eqation: $20*30*15%
first times $20*30=600
now, 600 *15%= $90
therefore, your answer is 90 dollars
Step #1: Find the slope.
Slope is "rise over run" and see the attached graph to see
the rise = 1
the run = 4
and this gives a slope of 1/4.
Step 2: Find the y-intercept.
The y-intercept is where this graph hits the vertical axis. That happens at a height of 20, so your y-intercept is (0,20) and your b-value for the slope-intercept form is 20.
Step 3: Put it all together:
y = mx + b becomes

Lou Ann needed 25 packages that contains all the 150 invitations.
Lou Ann needed to mail 150 invitations to her school play. The invitations came 6 to a package.
<h3>What is Statistic?</h3>
The statistic is the study of mathematics which deal with relations between comprehensive data.
Here, 1 package contains 6 invitation
so 1 package = 6 invitations
total invitation= 150 invitations
now number of packages = Total invitation/ 6 invitation = 150/6
=25
Thus the required number of packages is 25.

Applying the centroid theorem, the length of QR is: 12.
<h3>What is the Centroid Theorem?</h3>
- According to the centroid theorem, the centroid (the point where the three medians intersect) is 2/3 of the distance from the midpoint of the a side to each vertex opposite vertex of the triangle.
Given:
QU = 8
QU = 2/3(QR)
8 = 2/3(QR)
3(8) = 2(QR)
24 = 2(QR)
QR = 12
Therefore, applying the centroid theorem, the length of QR is: 12.

Answer:
x = 25
Step-by-step explanation:
0 = 2x - 50
0 - 2x = -50
-2x = -50
x = 25
