What is the value of e 18-e=4

Brainliest please

You would subtract 18 over so you have negative -14 equals -e or 14 equals e 

Common sense says 4 plus what equals 18, and it is 14. or if you want a mathematical way, subtract 18 from both sides, giving you -e=-14, divide both sides by -1, and you receive an answer, e=14.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
