Q. Combine like terms to create an equivalent expression.89m+109−2m−53
Identify Like Terms: Identify like terms in the expression. Like terms are terms that contain the same variable raised to the same power. In this expression, (89)m and −2m are like terms because they both contain the variable m to the first power. The constants (109) and −53 are like terms as well.
Combine Like Terms with Variable: Combine the like terms that contain the variable m. To combine 89m and −2m, we need to find a common denominator. The common denominator for 8 and 1 (since −2m can be written as −12×m) is 8. Convert −2m to −816m so that both terms have the same denominator.\frac{\(9\)}{\(8\)}m - \frac{\(16\)}{\(8\)}m = \left(-\frac{\(7\)}{\(8\)}\right)m
Combine Constant Terms: Combine the constant terms \((\frac{9}{10}) and −(53). To combine these, we need to find a common denominator. The common denominator for 10 and 5 is 10. Convert −(53) to −(106) so that both terms have the same denominator.(109)−(106)=(103)
Write Combined Expression: Write the combined expression using the results from the previous steps. The combined expression is (−87)m+(103).
