Answer:
A. 2/3 book/hour
Step-by-step explanation:
rewrite the fractions as a decimal if it can make it easier for you (0.5 book/0.75 hours) then divide which is 2/3 book/hour
The answer to this is the second choice
-2x + 16 = x + 28
-12 = 3x
X = -4
To equations are equivalent if and only if they have the same solution set.
Solve for both of the equations.
-2x = 10
x = -5 <-- Divide both sides by -2
-5x = 25
x = -5 <-- Divide both sides by -5
Both have the solution -5.
So, yes both are equivalent.
