18. Translate to an algebraic expression: Twenty less than some number.
Answer by jainenderkapoor(61) (Show Source): You can put this solution on YOUR website!
17. Solve: 0.1p+2.1=4.6p-1.9+0.5p
Arranging like terms on one side
0.1p - 4.6p - 0.5p = -1.9 - 2.1
-5p = -4
p = -4/-5 = 4/5 = .8

18. Translate to an algebraic expression: Twenty less than some number.
Let the number be denoted by x
algebraic expression can be written as x - 20

Hope the solution is clear to you. If you have any doubt you can contact me at jainenderkapoor@gmail.com I am also available for Online Tutoring at very reasonable rates.
