Whats 3.2r + 14.7=6.74
Nata [24]

<u><em>r=-199/80 is the right answer.</em></u> First, you had to multiply by 100 from both sides of the equation. And it gave us, 3.2r*100+14.7*100=6.74*100. Next, you had to refine, and it gave us, 320r+1470=674. Then, subtract by 1470 from both sides of equation. And it gave us, 320r+1470-1470=674-1470. Simplify, and it gave us, 320r=-796. You can also divide by 320 from both sides of equation. And it gave us, \frac{320r}{320}=\frac{-796}{320}. And finally, simplify, and it gave us the answer is <em><u>r=-199/80 is the right answer.</u></em> Hope this helps! And thank you for posting your question at here on brainly. And have a great day! -Charlie
