Answer:
30000+1000+80+4+0.5
Step-by-step explanation:
Expanded notation can be defined as to rewrite the numbers to show their place values
For example in the given question 3 is at the tenth thousand place, 1 is at the thousand'th place,8 at tenth and 4 at unit place so the solution for the question is given below:
30000+1000+80+4+0.5
3×10000+1×1000+8×10+4×1+(5×1÷10)
Volume of the first dwarf planet (r₁ = 832 mi):

Volume of the second dwarf planet (r₂ = 829 mi):

So difference between the volumes is:

or if we want exact value (we use (a³-b³) = (a-b)(a²+ab+b²) ):
2x + y = 3
3x - y = 12
Add both equations
5x = 15, x = 3
2(3) + y = 3
6 + y = 3, y = -3
Solution: x = 3, y = -3... or (3,-3)

Answer:=2/9z+−11/3. the reason why this would answer is because you would have to combine like terms
