Answer:
-7/12
Step-by-step explanation:
15/4 simplified is 3 3/4
so 3 3/4 - 4 1/3
this equals -7/12
Well if I am right 120% of 30 is 36, so they would pay 36 dollars in total
Hope this helps;-)
Answer:
Step-by-step explanation:
Part a is AB and CD because those lines are symmetrical.
Part D is the angle is the same as A so D is 30 as well. then for b and c since those are the same you take 180-30 to get 150 for both angles
We know that ∠1 equals ∠3, from that we can find x:
![10x = 100 \\ x = 10](https://tex.z-dn.net/?f=10x%20%3D%20100%20%5C%5C%20x%20%3D%2010)
The sum of ∠1 and ∠2 must equal 180°:
![10x + 10y + 20 = 180](https://tex.z-dn.net/?f=10x%20%2B%2010y%20%2B%2020%20%3D%20180)
Since we already know x, we can solve for y:
![10 \times 10 + 10y + 20 = 180 \\ 10y + 120 = 180 \\ 10y = 60 \\ y = 6](https://tex.z-dn.net/?f=10%20%5Ctimes%2010%20%2B%2010y%20%2B%2020%20%3D%20180%20%5C%5C%2010y%20%2B%20120%20%3D%20180%20%5C%5C%2010y%20%3D%2060%20%5C%5C%20y%20%3D%206)
Result: x=10, y=6
