6n+5, because you just subtract 9n with 3n
Answer:
True
Step-by-step explanation:
The null space of matrix is set of all solutions to matrix. The linearly independent vectors forms subset which are spanned and forms the null space. The null space of vector can be found by reducing its echelon. The non zero rows formed are the null spaces of matrix.
expression
A mathematical symbol, or combination of symbols, representing a value, or relation. Example: 2+2=4
So its asking for basically the percentage of the first number out of the second.
3. 25/50 = 50%
4. 125/75 = 167%
5. 32/28 = 114%
6. 7/10 = 70%
Hope this helped! :)
When you estimate, you round each number, the add.
We round them to
700+620, which is 1320
So our non estimated answer is 1323
But our estimated answer is 1320
