It is: 15x
0.5*xy
x = 2 is an algebraic equality (Because there is an 'equals'(=) sign) x - 2 is an algebraic expression ( Because there is NO equals sign).
an algebraic expression has no = sign. it could be like x+4, but an equation has to have an = sign. like x+4=5
The algebraic expression that represents the sum of 10 and 3 times a number x is 10 + 3x. This expression can be simplified by multiplying 3 with x to get 3x, and then adding 10 to it. In this expression, 3x represents three times the value of x, and 10 represents a constant value added to the product of 3 and x.
The Base in the Algebraic Expression can be a Number or A Variable. EX. 42 or X2 - 4 and X are the base.
X = 15 - 5y
3x
x/15
If you call your number x, the expression would be 5x.
2x+15
y - 5x
35-(4x)
9*(x+ 2)
15.x-12
They are two terms of an algebraic expression.
It is simply: x-1
0.5*xy
