Answer:

<em>width=20 cm</em>

Step-by-step explanation:

h=3 cm

w=5 cm

proportional rectangle:

   height=12

  • Here height has become 12 by multiplying 3 by 4.Therefore to find the width do the same thing.

 width=5*4

          =20 cm

The ratio will be same

  • Let width be x

\\ \sf\longmapsto \dfrac{3}{5}=\dfrac{12}{x}

\\ \sf\longmapsto 3x=5(12)

\\ \sf\longmapsto 3x=60

\\ \sf\longmapsto x=\dfrac{60}{3}

\\ \sf\longmapsto x=20cm

Which step brings you closest to getting the variable alone on one side of the equation
Oliga [24]

Answer:

Adding 5 from both sides then dividing by 7

Step-by-step explanation:

The best way to isolate x is to add 5 to both sides first:

21 = 7x

Then to isolate x by itself divide both sides by 7

x = 3

That would be the value of x and your final answer.
