How do i round 74,600 to the nearest thousand​
Nataly [62]

Answer:

75000

hope this helps u

brainliest pls

Step-by-step explanation:

Let 7.1239 is a decimal number. Now, we have to round the given decimal number to its nearest thousandth.

Step 1: Identity the thousandth digit. (Here, 3 is the digit which is in thousandth place)

Step 2: Now, look at the digit, which is next to the thousandth place. If that digit is less than 5, round down the thousandth digit. If that digit is greater than or equal to 5, round up the thousandth digit. From the example given above, the digit next to the thousandth digit (i.e., 9) is greater than 5, so we have to round up the thousandth digit.

Step 3: Thus, the number 7.1239 rounded to the nearest thousandth is 7.124.

Find the value of x.
nikklg [1K]

Answer:

x = 13

Step-by-step explanation:

Sum or interior angles of a triangle is 180,

6x + 19 + 5x - 15 + 3x - 6 = 180

6x + 5x + 3x + 19 - 15 - 6 = 180

14x + 19 - 21 = 180

14x - 2 = 180

14x = 180 + 2

14x = 182

x = 182 / 14

x = 13
