-5x-12>6x-4 Solve the inequality and give the answer in interval notation.

lora16 [44]

-5x-12>6x-4

To Solve the inequality we need to get x alone

-5x-12>6x-4

first we remove -12, for that we add 12 on both sides

-5x-12+12>6x-4+12

-5x > 6x +8

Now subtract 6x from both sides

-5x -6x> 6x-6x +8

-11x > 8

Divide by -11. when we divide by -11 we flip the inequality . so > becomes <

$x < -\frac{8}{11}$

We need to give the answer in interval notation.

x is less than -8/11 so x value starts from -8/1 and goes to -infinity(left)

So interval notation is (-∞, $-\frac{8}{11}$ )

Help with A and B plzzzz

Digiron [165]

a.) The height of the closet is 96 inches, and you want to have 4 rows, so you divide the total height 96 by 4

96 ÷ 4 = 24

So each cube organizer can be a height of 24 inches since it divides out evenly

b.) Each shoe box is 4 1/2 inches, because there are 3 boxes that are stacked on top of each other, you can multiply 4 1/2 by 3, or you can do 4 1/2 + 4 1/2 + 4 1/2.

4 1/2 + 4 1/2 + 4 1/2 = 12 3/2 = 13 1/2

The total height of the 3 boxes is 13 1/2
