Answer:
D) In step 5, he should have multiplied both sides by 1/3
Step-by-step explanation:
Given expression,
Using distributive property,
Using additive property of equality,
Make the fraction with same denominator by taking LCM of Denominators in left side the equation,
Adding fractions,
Write 3 as a fraction,
Using multiplicative property of equality for isolating the variable in right side, multiply 1/3 in both sides,
Hence, it is clear that he did mistake in step 5 he should have multiplied both sides by 1/3.

Answer:
AB is 31.
Step-by-step explanation:
So we know that B is the midpoint of AC. This means that:
by the definition of midpoint.
We know that AB is 2x+1 and BC is 5x-44. Substitute:
Now, find the value of x.
Subtract 1 from both sides:
Subtract 5x from both sides:
Divide both sides by -3:
So, the value of x is 15.
AB is 2x+1.
Substitute 15 into x. So:
Multiply:
Add:
So, the length of AB is 31.
And we're done!
