572000 square miles rounded ro the nearest hundred thousand

Hello!

To round a number to the nearest hundred-thousand, take every number after the first number in the sequence (in this case, it would be 5) and change it into a zero.

572,000 becomes 500,000.

Now, depending on the number after 5 (in this case, it's 7), we can determine whether 5 becomes 6, or if it stays the same. If the number that comes after 5 is greater than or equal to 5, then 5 becomes 6. Since 7 is greater than 5, 5 will become 6.

500,000 becomes 600,000.

600,000 is your answer.

But that was sort of confusing, right? No worries! Let's do an example problem.

Round 329,782 to the nearest hundred-thousand.

We'll start with changing everything behind 3 to a zero.

329,782 becomes 300,000.

Now, depending on the number directly after 3, it either stays the same, or becomes 4. If the number behind 3 is 5 or greater, then 3 will become 4.

The number behind 3 is 2. 3 stays the same. Your answer for this example problem is 300,000.

Your answer is 600'000 Have a good day

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
