<span>3x+2 (5x+4)=47
47- 4 = 43
43/5= 8.6
8.6-2= 6.6
6.6/3= 2.2
2.2 <-- answer</span>
Answer:
84
Step-by-step explanation:
sum of interior angles of a pentagon is 540. A triangle is 180, then for each side you add another 180, so a square would be 360 and a pentagon is 540
Sum up all given sides
131+108+107+110=456
subtract this number from 540
540-456=84
x degree= 84
You do 3-3=0 (it basically cancels each other out) then you do 12-3=9. So you have
Y=15x-9
N/P=10^26/(10^22)
N/P=10^4
N/P=10000
The mass of Neptune is approximately 10,000 times greater than that of Pluto.
