Answer:

x=8

Step-by-step explanation:

Make all the denominators the same

3(x-4/10)=6(3/5)-2(x-5/15)

(3x-12)/30=18/30-(2x-10)/30

Cancel out all the denominators because they're the same

3x-12=18-2x+10

3x-12=28-2x

Add 12 to both sides

3x=40-2x

Add 2x to both sides

5x=40

Divide both sides by 5

x=8

Answer:

The width of the window should be $7.6\ ft$ and the height of the window should be $3.8\ ft$

Step-by-step explanation:

we know that

The circumference of a semicircle (window) is equal to

$C=\pi r$

we have that

$C=12\ ft$

$\pi=3.14$

substitute and solve for r

$12=(3.14)r$

$r=12/3.14=3.8\ ft$

the width of the window is equal to the diameter of the semicircle

The width of the window should be $3.8*2=7.6\ ft$ and the height of the window should be $3.8\ ft$
