Answer:
x = 5, y = 2
Step-by-step explanation:
First, isolate y in the top equation.

Next, substitute y in the bottom equation.


Simplify.

Combine like terms.

Isolate x on one side.

Isolate x.

Substitute x into 

Simplify.

Isolate y.


After putting the value of y from the second equation to the first equation, the resultant equation is
.
GIven:
The equations are:

It is required to put the value of y from second equation to the first equation.
<h3>How to solve equations?</h3>
The value of y from the second equation is,

Now, put this value of y in the first equation as,

Therefore, after putting the value of y from the second equation to the first equation, the resultant equation is
.

Answer:
we can use centeroid formula of a triangle
that is (x1+x2+x3)/3
hope that helps : )
Answer:
MK
Step-by-step explanation:
ML is the short side of right triangle MLK. MJ is the hypotenuse of right triangle MKJ. This gives you a clue that the ratios of interest are the short side to the hypotenuse. All these right triangles are similar, so ...
ML/MK = MK/MJ . . . . . ratio of short side to hypotenuse is the same
ML·MJ = MK² . . . . . . . cross multiply
MK = √(ML·MJ) . . . . . the geometric mean of ML and MJ is MK
100 divided by 7 is 14 r 2, so there are 2 left over
