21-6n+2(2n-5)-3n

First, multiply 2x2n and 2x-5

21-6n+4n-10-3n

Then rearrange the terms

4n-6n-3n+21-10

Then combine like terms

-5n+11

hope it helps!

A student read 3 000 146 as "three thousand one hundred forty-six." how do you explain the students error
Mumz [18]
The digit 3 is in the millions place value, hence it is worth three million, not three thousand.
Therefore, 3,000,146 should be read as three million, one hundred and forty-six, and NOT three thousand, one hundred and forty-six.
Hope this answer helps you! If it did, please mark it as the brainiest! I would really appreciate it! :)
