Answer:
B) She is incorrect because when substituting 2 for m the result was a false statement.
Step-by-step explanation:
Let's solve it for ourselves and see if Mia is correct:
7.8+2(0.75m+0.4)=-6.4m+4(0.5m-0.8)
7.8+1.5m+0.8=-6.4m+2m-3.2
1.5m+8.6=-4.4m-3.2
8.6=-5.9m-3.2
11.8=-5.9m
-2=m
m=-2
Since the answer is actually m=-2, Mia's guess is incorrect because plugging in m=2 does not make both sides equal. Therefore B is the correct option.
<h2>Maneuvering an equals sign</h2><h3>Concept</h3>
Learn the rules and implications of moving numbers across an equals sign to combine like terms.
<h3>Utilization</h3>
When you move a negative number across an equals sign (in incredibly linear equations), you should always add it, the inverse (subtract) goes for positive numbers.
<h3>Answer</h3>
x = -11
