Remember that like terms can be combined only.
Thus, for given expression, the terms which can be combined is given by:
Option C: 6.2y can be combined with -3/8y.
Given that:
- To find which terms can be combined in [tex]-13 -\dfrac{x}{5} +6.2y +20.5x -\dfrac{3}{8}y[/tex]
Only like terms can be combined in given expression.
What are like terms?
Like terms are those terms which have same variables and their powers.
For given expression, the terms -x/5 and +20.5x have same x variable with single power.
The terms +6.25y and -3y/8 are also like terms.
Both can be combined.
The result will be:
[tex]-13 -\dfrac{x}{5} +6.2y +20.5x -\dfrac{3}{8}y = -13 + (-\dfrac{1}{5} + 20.5)x + (6.2 -\dfrac{3}{8})y[/tex]
Since given options contains only +6.25y and -3y/8, thus:
Option C: 6.2y can be combined with -3/8y is correct.
