Answer:ok
Step-by-step explanation:
2(7n-3)=-n+114
14n-6=-n+114
15n=120
n=8
check...
2(7*8-3)=-8+114
2(56-3)=106
2(53)=106
106=106
To find an improper fraction, you want to do 18* 7 which equals, 126, so then 126+4=130. So then 130/7 would be your answer.
2(2) + 3(3) =
4 + 9 = 13
I don't know what 90p means but basically, u have to multiply that by 3 and add it to our current total which is 13.
Then, u substract the total cost from the 20 and you should get the change.
Its a chemical element, and it is surrounded by electrons.
