Q. Rewrite in simplest terms: 9(−0.6r+0.8)+7(0.3r−0.6)Answer:
Distribute Terms: Distribute the 9 and 7 into their respective parentheses.We need to multiply each term inside the parentheses by the number outside the parentheses.For the first set: 9×(−0.6r)=−5.4r and 9×0.8=7.2For the second set: 7×(0.3r)=2.1r and 7×(−0.6)=−4.2
Combine Like Terms: Combine like terms.Now we add the results of the distribution together, combining the r terms and the constant terms.−5.4r+2.1r=−3.3r7.2−4.2=3
Write Final Expression: Write the final simplified expression.Combine the results from Step 2 to get the final simplified expression.−3.3r+3
