1/2> -1/6-2/9x
someone pls explain how to do fractions

1/2>-1/6-2/9x  

Move -1/6 to the other side. Sign changes from -1/6 to 1/6.

1/2+1/6 >-1/6+1/6-2/9x

1/2+1/6 >-2/9x

Find the common denominator for 1/2 which is 6.

Multiply by 3 for 1/2.

1(3)/2(3)=3/6

3/6+1/6 >-2/9x

4/6>-2/9x

Reduce 4/6 by diving by 2.

4/2=2

6/2=3

2/3>-2/9x

Multiply both sides by -9/2.

2/3(-9/2)>-2/9x*-9/2

Cross out 2 and 2, divide by 2 and then becomes. 1*1=1

Cross out 3 and -9, divide by 3 and then becomes. 3/3=1, -9/3=-3

1*-3=-3

-2/9x*-9/2= 1*1*x=x ( because of crossing out the numbers)

x >-3

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
