Q. Combine like terms to create an equivalent expression.−3.6−1.9t+1.2+5.1t
Identify and group like terms: Identify and group like terms in the expression −3.6−1.9t+1.2+5.1t.The like terms are the constants −3.6 and 1.2, and the terms with the variable t, which are −1.9t and 5.1t.Grouping the like terms gives us (−3.6+1.2)+(−1.9t+5.1t).
Combine the constants: Combine the constants −3.6 and 1.2.−3.6+1.2=−2.4
Combine the terms with the variable t: Combine the terms with the variable t, −1.9t and 5.1t.−1.9t+5.1t=3.2t
Write the equivalent expression: Write the equivalent expression by combining the results from the previous steps.The equivalent expression is −2.4+3.2t.
