We can solve this by elimination, in order to do this we need to multiply the bottom equation by three to cross out the X
(x+5y=38)3 3x+15y=114
-3x+4y=95
3x+15y=114
then add the two equations together and the X will cancel out
19y=209
----- -----
19 19
y=11
then plug that in into one of the equations
x+55=38
-55 -55
x= -17
your answer is (-17,11)
In decimal form its 0.64 and in fraction form its 16/25 :) (simplified from 64/100)
Answer:
The answer is B) G
Step-by-step explanation:
G is at the center of the triangle. It is a centroid because it is where all the medians meet.
Answer:
49.7%
Step-by-step explanation:
A cdircle is located within a square.
<u>Area of the circle</u>
Area = 
, where r = 4 units.
Area Circle = 50.3 units^2
<u>Area of the square</u>
Area = l*w or l^2 for a square, since l = w
Area = (10 units)^2
Area = 100 units^2
<u>Area in the square but outside the circle</u>
This is the difference [Square minus Circle Areas]
Square minus Circle Areas = 100 - 50.3 or <u>49.7 units^2</u>
<u>Probability</u>
The probability of picking a point in the square that is not in the circle is the ration of the two areas: <u>[Outside Circle/Square]x100%</u>
<u></u>
<u>(</u>49.7 units^2)/(100 units^2)x100% = 49.7%
<u></u>

because there are a total of 15 grid and the question asked to pick the grid that doesn't shaded
