Dimensional Analysis is the way you want to go

Answer:
B) Multiplying by 0
Step-by-step explanation:
This answer is correct because lets say we have a nonzero number, (IN this case lets say 4) 4+0 is 4, and that does not change the value because it is still 4, so A is not correct. Multiplying by 1 and dividing by one leads to the same conclusion. They both wind up to 4. The only one is B) because 4x0 is 0 and that isn't 4, so it changes value.
Hope this helped :)
Answer:
3
Step-by-step explanation:
maybe??? or 12 ........
4(3x - 1) = 24
First, divide both sides by 4. / Your problem should look like: 3x - 1 =

.
Second, simplify

to 6. / Your problem should look like: 3x - 1 = 6.
Third, add 1 to both sides. / Your problem should look like: 3x = 6 + 1.
Fourth, simplify 6 + 1 to 7. / Your problem should look like: 3x = 7.
Fifth, divide both sides by 3. / Your problem should look like: x =

which is your answer.
