what is 3x + 7 > -5

x > -4

Step-by-step explanation:

Isolate the variable, x. Treat the greater than sign like a equal sign, in that what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 7 from both sides:

3x + 7 (-7) > -5 (-7)

3x > - 5 - 7

3x > -12

Next, isolate the variable, x, by dividing 3 from both sides:

(3x)/3 > (-12)/3

x > (-12)/3

x > -4

x > -4 is your answer.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
