Answer :
Let's solve the math problems step by step. Here, each equation involves basic arithmetic operations with like terms, represented as 'c'.
a) [tex]33c + 40c + 15c[/tex]
To solve this, we combine the coefficients of 'c'.
[tex]33 + 40 + 15 = 88[/tex]
So, the simplified expression is:
[tex]88c[/tex]
b) [tex]83c - 34c[/tex]
Here, we subtract the second coefficient from the first:
[tex]83 - 34 = 49[/tex]
Thus, the result is:
[tex]49c[/tex]
c) [tex]62c + 8c + 39c[/tex]
Combine the coefficients:
[tex]62 + 8 + 39 = 109[/tex]
Therefore, we have:
[tex]109c[/tex]
d) [tex]68c - 23c[/tex]
Subtract the second coefficient from the first:
[tex]68 - 23 = 45[/tex]
Therefore, the simplified result is:
[tex]45c[/tex]
By following these steps, we've simplified each expression by combining or subtracting the coefficients of 'c'.
