Answer:Use PEMDAS (Please Exuse MyDear AuntSally)
Since there are no parentheses or exponents we go to the next thing which is multiplication and division.6×10=60.Then you divide that by 2 to get 30.Then do 17-30=-13.Then -13+12=-1.
I hope this helps
Answer:
Step-by-step explanation:
Given the inequality −x − 10 > 14 + 2x
This are the steps to solve the expression for x;
−x − 10 > 14 + 2x
Step 1: Add to to both sides
−x − 10+10 > 14 + 2x+10
-x > 24+2x
subtract 2x from both sides
-x-2x >24+2x-2x
-3x>24
Divide both sides by 3;
-3x/-3 < 24/-3
x < -8 (Note the change in inequality sign. It was changed because we divided through with a negative value)
