Evaluate the expression when r = 8.2 and s = –3.7. r – 2s A. –22.94 B. 0.8 C. 4.5 D. 15.6

OpenStudy (aihberkhan):

Okay. All you have to do is plug in \(-3.7\) for \(s\) and plug in \(8.2\) for \(r\)

OpenStudy (faiqraees):

r-2s 8.2 - 2(-3.7)

OpenStudy (aihberkhan):

When you do that the equation should look like: \(8.2 - 2(-3.7)\)

OpenStudy (aihberkhan):

So what is \(-2 * -3.7\)? @cupcakeohla

OpenStudy (anonymous):

11.9

OpenStudy (aihberkhan):

Nope it actually equals \(-7.4\). Then you want to do \(8.2 - (-7.4)\)

OpenStudy (aihberkhan):

Then you will have your answer! :)
