Solve the inequalities:
3(m-5) - 6 > -36
What do I do?

Answers

3(m - 5) - 6 > -36

First, add 6 to both sides. / Your problem should look like: 3(m - 5) \ \textgreater \  -36 + 6
Second, simplify -36 + 6 to get -30. / Your problem should look like: 3(m - 5) \ \textgreater \  -30
Third, divide both sides by 3. / Your problem should look like: m - 5 \ \textgreater \   -(30)/(3)
Fourth, since 10 × 3 is 30, simplify the fraction by 10. / Your problem should look like: m - 5 \ \textgreater \  -10
Fifth, add 5 to both sides. / Your problem should look like: m \ \textgreater \  -10 + 5
Sixth, simplify -10 + 5 to get -5. / Your problem should look like: m \ \textgreater \  -5

Answer: m > -5


3(m−5)−6>−36

3m−21>−36

Step 2: Add 21 to both sides.

3m−21+21>−36+21

3m>−15

Divide both sides by 3.

3m/3>−15/3

m>−5

Answers

move constant to other side
add 1
4c^2-8c=1
divide by 4 to make leading coeficient 1
c^2-2c=1/4
take 1/2 of linear coeficient and square it
-2/2=-1, (-1)^2=1
add that to both sides
c^2-2c+1=1/4+1
factor perfect squaer and add
(c-1)^2=5/4
square root both sides
c-1=+/-(√5)/2
add 1
c=1+/-(√5)/2

c=2.12 or -0.12
