What is k/5.2 + 81.9= 47.2
weqwewe [10]
Solution for k/5.2+81.9=47.2 equation:
<span>k in (-oo:+oo)

k/5.2+81.9 = 47.2 // - 47.2

k/5.2-47.2+81.9 = 0

0.19230769*k-47.2+81.9 = 0 // - 81.9-47.2

0.19230769*k = -(81.9-47.2) // : 0.19230769

k = (-(81.9-47.2))/0.19230769

k = 5.20000006*(47.2-81.9)

k = 5.20000006*(47.2-81.9)

Always Practice, It makes Perfect! Anyways, I hope I helped... It would be nice if you can answer mine too, But you dont have to! ;) </span><span>brainly.com/question/253764
