5 < k -2 < 11 ? -4 > y + 2 > -10 ?
5 -m < 4 or 7m > 35 ?
3 < 2p -3 < 12 ?

Step-by-step explanation:

Given

Required

Solve

Solving (1):

The above can be represented as:

and

Solving

Solving

So, we have:

and

This can be combined as:

Solving (2):

Split as:

and

Solving

Solving

So, we have:

and

This gives

Solving (3):

Solve for m in both cases:

Divide both sides by 5

So, we have:

or

The solution is because

Solving (4):

The above can be represented as:

and

Solving

Add 3 to both sides

Divide both sids by 2

Add 3 to both sides

Solve for p

So, we have:

and

Combined as:

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'.

this is answer of 144 cubic meters
