It is: 15x
0.5*xy
an algebraic expression has no = sign. it could be like x+4, but an equation has to have an = sign. like x+4=5
no
The Base in the Algebraic Expression can be a Number or A Variable. EX. 42 or X2 - 4 and X are the base.
12/x
X = 15 - 5y
3x
x/15
If you call your number x, the expression would be 5x.
7 + x
2x+15
35-(4x)
y - 5x
9*(x+ 2)
15.x-12
They are two terms of an algebraic expression.
It is simply: x-1
