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!
<span>In getting the value of R in the formula of the circumference that you give where as the circumference is equals to 15, the derived formula is R=C/2pi and the answer would be that R is equals to 2.39. I hope you are satisfied with my answer and feel free to ask for more if you have more questions and further clarifications </span>
It typically just needs two parts
1) all parties must be in agreement
2) something of value needs to be exchanged. ie. money, a service
Try -×=4??? i just started to learn how to do variable expressions correctly bc i just transfered to an high accelerating school, but if I'm wrong w the answer im very sorry, as i am just now learning.
To help explain how you get A for the answer:
work backwards
5(3a²+11a-4)
multiply everything by 5
5×3a²=15a²
5×11a=55a
5×-4=-20
15a²+55a-20
