Question

Whats 3.2r + 14.7=6.74

Answer 1

Answer:

Step-by-step explanation:

Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 14.7 from both sides

3.2r + 14.7 (-14.7) = 6.74 (-14.7)

3.2r = 6.74 - 14.7

3.2r = -7.96

Isolate the r. Divide 3.2 from both sides

(3.2r)/3.2 = (-7.96)/3.2

r = -7.96/3.2

r = -2.4875

-2.4875 is your answer

Answer 2

r=-199/80 is the right answer. 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 r=-199/80 is the right answer.
