Answer:
1 ) 180 - 71 = 109
2) 5x +x = 180 ; 6x = 180 ; x = 180/6 = 30
3) 90
4) x + 6x+8 + x+12 = 180 ; 8x + 20 = 180 ; 8x = 160/8= 30
5) 180 -110 = 70
6) m = 180- 119 = 61
7) 90
8) 11y - 36 = 63 ; y = 99/11 = 9

(Q7) 180
(Q8) 2x+x = 3x = 90 ; x = 90/3 = 30
(Q15) 157
(Q16) 5x + 4 + (x-2) + (3x+7) = 180
9x +9 = 180 ; x = 171 / 9 = 19
I hope im right!!
Answer:
6 and 8
Step-by-step explanation:
6+8=14 difference 2
(2/3)x+4= 7
Subtract 4 from both sides
(2/3)x= 3
Divide both sides by 2/3. To divide by a fraction, multiply the first number by the reciprocal of the second.
3*3/2= 9/2
Final answer: 9/2 or 4.5
Formula:

![length=15inches](https://tex.z-dn.net/?f=length%3D15inches)
![width=?](https://tex.z-dn.net/?f=width%3D%3F)

![2*15=30](https://tex.z-dn.net/?f=2%2A15%3D30)
(There are two sides for the length)

![24/2=12](https://tex.z-dn.net/?f=24%2F2%3D12%20)
(There are two sides for the width)
The width of the desk is 15 inches
