Answer:
Hi! The correct answer is x=-19/2
Step-by-step explanation:
<em><u>~Solve for x by simplifying both sides of the equation, then isolating the variable~</u></em>
180-2(55)-x=0
180-110-x=0
70-x=0
-x=-70
x=70°
Answer:
y = -2x + 8 is the answer to the question
Answer: 0.8 or 80% (either way is correct)
Explanations 80/100 equals 80 divided by 100 which equals 0.8 ; 0.8 equals 80%
