6/5 +15.4
12/10 +15.4
12/10+154/10
166/10
16.6
This can also be done by using the following method:
6/5 +15.4
12/10+15.4
1.2+15.4
16.6
Hope this helps :)
Answer: x = 16
Step-by-step explanation:
Supplementary means when the two angles are added together they equal 180 degrees.
(6x+8) + (4x+12) = 180
10x + 20 = 180
10x = 160
X = 16
Answer: 32 room
Step-by-step explanation:
![7\frac{3}{4} =\frac{4(7)+3}{4} =\frac{28+3}{4} =\frac{31}{4}=7.75](https://tex.z-dn.net/?f=7%5Cfrac%7B3%7D%7B4%7D%20%3D%5Cfrac%7B4%287%29%2B3%7D%7B4%7D%20%3D%5Cfrac%7B28%2B3%7D%7B4%7D%20%3D%5Cfrac%7B31%7D%7B4%7D%3D7.75)
<u>If 1 room = 7.75 yd of carpet ⇒ x rooms = 250 yd of carpet</u>
Use proportions & cross-multiply to solve:
![\frac{1}{7.75} =\frac{x}{250}\\7.75x=250\\x=\frac{250}{7.75} =32.258](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7.75%7D%20%3D%5Cfrac%7Bx%7D%7B250%7D%5C%5C7.75x%3D250%5C%5Cx%3D%5Cfrac%7B250%7D%7B7.75%7D%20%3D32.258)
So 250 yd of carpet can cover about 32 rooms.
