Please help me, i promise its worth it!!!
Rashid [163]

\\ \sf\longmapsto 2(L+B)=55

\\ \sf\longmapsto 2(\dfrac{4}{3}x+x)=55

\\ \sf\longmapsto \dfrac{8}{3}x+2x=55

\\ \sf\longmapsto \dfrac{8x+6x}{3}=55

\\ \sf\longmapsto \dfrac{14x}{3}=55

\\ \sf\longmapsto 14x=165

\\ \sf\longmapsto x=11.78

\\ \sf\longmapsto x\approx 12

Now

  • B=x=12
  • L=4/3(12)=4(4)=16

Solve the linear equation:<br><br> 3.4 + 2(9.7 – 4.8x) = 61.2
Ganezh [65]

Answer:

- 4

Step-by-step explanation:

(2*(Rationalize(9.7)-Rationalize(4.8x)))==Rationalize(61.2)-Rationalize(3.4)

Rationalize(18.4)-Rationalize(2.8x)

==Rationalize(57.8)

-Rationalize(2.8x)==Rationalize(57.8)-Rationalize(18.4)

x= 38.4÷-2.8
