Step-by-step explanation:

For this exercise it is important to remember the meaning of the symbols of inequalities. These are:

means "Less than".

means "Greater than".

means "Less than or equal to".

means "Greater than or equal to".

Let be "t" the the temperature (in °F) of the refrigerator.

According to the information given in the exercise, the temperature inside the refrigerator is no more than .

In other words, the temperature inside the refrigerator is less than or equal to .

Knowing this, you can write the following inequality to represent this situation:

nope

step-by-step explanation:

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'.
