For number 30, its easier if its broken down so were going to make it √200*x^2*y^2*z^2. We can't get a square root of 200 so we will break it into 100*2 to get √2*100*x^2*y^2*z^2. Now let's look at what we can take the square roots of. 2 doesn't have a nice sq. rt. so we will leave it there. 100 has the rt. of 10 so we can make 10√2*x^2*y^2*z^2. X^2 has the root x and we can follow this with the other variables to get 10xyz√2. There is your final simplified answer.
Hi
if she recieived 13 bills and 4 are 10 $? then we have 13-4= 9 20$ bills
so 4x10 +9x20 = 40+180 = 220
So yes it's true
Let x = the original price.
With 25% off, the price drops to
0.75x.
With another 5% off, the price drops to
0.95*(0.75x) = 0.7125x
Add 8.25% tax, and the price goes up to
1.0825*(0.7125x) = 0.7713x
This is equal to the amount paid, so
0.7713x = 384.87
x = 384.87/0.7713 = $498.99
Answer: Original price = $498.99
The ratio of the frequency at which he picks blue is 18:32 which simplifies to 9:16 but if you want a percentage its 36%
Given:
The inequality is:

To find:
The graph for the given linear inequality in the coordinate plane.
Solution:
We have,

The related equation for this inequality is:

The table of values is:
x y
0 3
-1 -2
Plot the points (0,3) and (-1,-2) on a coordinate plane and connect them by a dotted straight line because the sign of inequality is >.
Check the given inequality for (0,0).


This statement is true. So, the shaded area of the given inequality is towards the origin.
Therefore, the required graph is shown below.
