I don't get it, what are you suppose to do?
Let h equal the number of hours the electrician works.
We can write the equation like this:
90h + 60 = 600
Solve for h.
90h + 60 = 600
~Subtract 60 to both sides
90h + 60 - 60 = 600 - 60
~Simplify
90h = 540
~Divide 90 to both sides
90h/90 = 540/90
~Simplify
h = 6
Therefore, the electrician work for 6 hours.
The correct answer is Option 1.
Best of Luck!
Answer:
4 × 5 × 6 × 1012 = 121440
= 1.2 × 10⁵
The answer really depends on what b is. Unless you give me a number for what b equals I can’t solve it.
