3 ÷ x = 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Multiplication Property of Equality] Multiply <em>x</em> on both sides: 3 = 6x
- [Division Property of Equality] Divide 6 on both sides: 3/6 = x
- Simplify: 1/2 = x
- Rewrite: x = 1/2
Hello:
Increase in length is : (30×10)/100 =3 cm
Increase in width is : (20×5)/100 = 1 cm
the new length is : 30 cm+3cm =33 cm
the new width is : 20cm+1 cm =21 cm
the perimeter is : 2(20+30) = 100 cm
the new perimeter is : 2(33+21) = 108 cm
the pourcentage increase in the perimetr is : 8%
108 =100/100+8/100=1+8/100
