Answer:
2 1/4
Explanation:
Like terms are terms which have the same variable and exponent. They sound alike and look alike. Here 1.45x and -7.78x are like terms. 3.5t is not because it has a different variable. None of the previous terms are like terms with -5.92 because it has no variable. Only 2 1.4 which also has no variable is a like term.
