15 - 2x
15-2
15-2x
18 - 3n
y = 125 - x
4-(n/7) *the foreward slash represents the divided by sign
p+0.4-(p+0.4)5 i think
4x
It can be: x-7
the + of a number and 10 k decreased by 4 = k-4
18 - 3n
It can be: 7-4x as an algebraic expression
y = 125 - x
If x is the unknown variable then it can be: x-16
n (number) minus four ----->n-4
Let x be the number and so it is: 3x-18
(x - 25)*4
n = number 2(n + 15) ======
Here is the correct defenition: Algebraic Expression is an expression which is obtained by performing a finite number of the following operations on symbols representing numbers: addition, subtraction, multiplication, division, raising to a power.
