Alright first things first you need to distrubute 6(x-5) so that will be 6x-30=54
In order for you to get x by itself you need to add -30 on both sides so that'll be your second step is to add -30 on both sides: -30+-30 54+-30. Cancel out -30 and add the 54 and -30 together and you'll get 24.
Third and final step you have 6x=24 but you aren't done yet. You need to get X by it self so divide 6 on both sides. Cancel out the x and now you have x by itself. Divide 24 and 6 and you'll get 4
So your answer will be x=4.
Hope this helped :)
have a great day
I will be glad to help you in the comments. I do need to know though, what is the class this is presented in? Is this algebra, or calculus? Depending on the class, we have different approaches.
Answer:
It is the first choice.
Step-by-step explanation:
This is a sequence where
the next term is obtained by adding 6.
first term = -9 + 6(0) = -9
second term = -9 + 6(1) = -3
third term = -9 + 6(2) = 3
4th term = -9 + 6(3) = 9
and 81 = -9 + (6*15).
So the answer is Sigma (-9 + 6n) from n= 0 to n = 15.
Answer:
50
40
You have them right
Step-by-step explanation:
If he is charging 40 per hour, take away 40 from 90 because this is the first hour. Meaning at hour 0, there are 50 dollars.
