Answer:

I will gladly help (see explanation)

Step-by-step explanation:

1. 8.21n−5.3−(7+11.8n)

Distribute the Negative Sign:

=8.21n−5.3+−1(7+11.8n)

=8.21n+−5.3+(−1)(7)+−1(11.8n)

=8.21n+−5.3+−7+−11.8n

Combine Like Terms:

=8.21n+−5.3+−7+−11.8n

=(8.21n+−11.8n)+(−5.3+−7)

=−3.59n+−12.3

(Hope his helped, Good Luck! )

Answer:

-3.59 - 12.3

Step-by-step explanation:

Algebraic Expressions

Algebraic Expressions are similar to numerical expressions but instead of just numbers, alphabet variables are being used as well.

Note: BODMAS rule applies to Algebraic Expressions as well.

Eg. 7x + 4 + 5y + 4x = 11x + 5y + 4

Solution

Given from the question:

(8.21n - 5.3) - (7 + 11.8n)

= 8.21n - 5.3 - 7 - 11.8n

= 8.21n - 11.8n - 5.3 - 7

= -3.59n - 12.3

Therefore, the answer is -3.59 - 12.3.
