Answer:

At the bottom!

Step-by-step explanation:

Put the two equations into the same standard form:

2x-y=8

-5x+2y=3

Now if you add the two equations up, guess what will happen?

You will "eliminate" the y variable, and only be left with the x variable.

Technically, you will get:

2x-y+2+28-5x+29+2y=8+23

-3x+20y=11

-3x=11

If the length of a leg of a triangle is 39.2 and the area of the triangle is 63 what is the length of the other leg

Nadya [2.5K]

Answer:

The length of the other leg is $3.21\ units$

Step-by-step explanation:

I will assume that the triangle is a right triangle

In a right triangle the legs are perpendicular

The area of a right triangle is equal to

$A=\frac{1}{2}(a)(b)$

where

a and b are the legs of the triangle

In this problem we have

$a=39.2\ units$

$A=63\ units^{2}$

substitute the values

$63=\frac{1}{2}(39.2)(b)$

$126=(39.2)(b)$

$b=126/(39.2)=3.21\ units$
