Answer: D) 12</h3>
=========================================================
Work Shown:
The smaller angles UVN and NVW add up to the largest angle UVW.
This is due to the angle addition postulate.
(angle UVN) + (angle NVW) = angle UVW
(6x+13) + (46) = 11+10x
6x + 59 = 11 + 10x
6x - 10x = 11 - 59
-4x = -48
x = -48/(-4)
x = 12
----------------
Extra info:
If you're curious about the angles, then we use that x value to find them
- angle UVN = 6x+13 = 6*12+13 = 72+13 = 85 degrees
- angle NVW = 46 degrees
- angle UVW = 11+10x = 11+10*12 = 11 + 120 = 131 degrees
Note how 85+46 = 131 to show that (angle UVN) + (angle NVW) = angle UVW is a true equation. This confirms our answer for x.

Answer:
Step-by-step explanation:
(5, -30) (6, -36)
(-36 + 30)/(6 - 5) = -6/1 = -6
y + 30 = -6(x - 5)
y + 30 = -6x + 30
y = -6x + 0
y = -6x
The answer I believe is the second one to the top
Square x first then add x then subtract by 2
All together: <span>3x + 0.05 + x + x + 0.10 = 7.50
5x + 0.15 = 7.50
5x = 7.35
x = 1.47
</span>1.47 +0.10=1.57<span>
so, the drink costs 1.57 </span>
