Use substitution method <br>3x +4y+175x-2y=11

Viefleur [7K]

$3x +4y+175x-2y=11$

$4y-2y+175x+3x=11$

$2y+178x=11$

$2y=11-178x$

$y=\frac{11-178x}{2}$

$y=-89x+\frac{11}{2}$

$178x=-2y+11$

$x=\frac{-2y+11}{178}$

$x=\frac{-1}{89} y+\frac{11}{178}$

Juanita and lauren are painting a circular mural on one wall of the community center. The area of the mural is 33 square meters

tangare [24]

Answer:

The radius is 3.24102 meters

Step-by-step explanation:

We are given

area of mural is 33 m^2

Since, the shape of mural is circular

Let's assume radius of circle as 'r'

so, we can use area of circle formula

$A=\pi r^2$

now, we can set A=33

and then we can solve for r

$33=\pi r^2$

we get

$r^2=\frac{33}{\pi }$

$r=3.24102$

So,

The radius is 3.24102 meters
