Rounded to the nearest thousandth, what is the decimal equivalent of?
Archy [21]
<span>Rounding Decimals to the Nearest Thousandth - Math A Tube. Number to the right of the thousandth digit is 4. Remember: If less than 5, round down.

</span><span>To round numbers to the nearest thousand, make the numbers whose last three digits are 001 through 499 into the next lower number that ends in 000. For example, 6424 rounded to the nearest thousand is 6000. Numbers that have the last three digits of 500 or more should be rounded up to the next even thousand.

</span><span>If we want to round 4.732 to 2 decimal places, it will either round to 4.73 or 4.74. 4.732 rounded to 2 decimal places would be 4.73 (because it is the nearest number to 2 decimal places). 4.737 rounded to 2 decimal places would be 4.74 (because it would be closer to 4.74).</span>

4(x + 5) – 13x = 263 step by step .
kotykmax [81]

Answer:

x = -27

Step-by-step explanation:

4(x+5) - 13x = 263

Multiply

4x + 20 - 13x = 263

Subtract 20 from both sides

4x - 13x = 243

-9x = 243

Divide by 9 on both sides

x = -27

Hope this helps :)

Given a side of a Square is 3cm. Find area and perimeter of the square. ​
anastassius [24]

Answer:

Area: 9cm²

Perimeter: 12 cm

Explanation:

Area is length x width

It's a square so length and width are the same

3 times 3 is 9

And to find the perimeter you just add the side lengths

Squares have 4 sides and the given side length is 3 so 3x4 OR 3+3+3+3 is how you get the perimeter.
