Answer:

Step-by-step explanation:
We want to arrange the following numbers on the number line in order from least to greatest.
The numbers are:

Let us convert everything into decimals to get:

Rearranging from least to greatest, we have:

Just substitute - 2 into x and solve.
80,000.
To round up to the nearest ten thousand, we would see if the next lower place value has a amount either 5 or higher or 4 or lower.
If it’s five or higher, we round up.
If it’s four or lower, we round down.
We can see that the number in the ten thousands place is 8. The number in the place value after 8 is 2.
2<5 so we round down.
The answer is 80,000.
Hope this helps!
