It can be: 7-4x as an algebraic expression
4x
X = " a number " X + 20
Write the general algebraic expression for each using matchstick?
x2+7
It can be: 7-4x as an algebraic expression
18 - 3n
the + of a number and 10 k decreased by 4 = k-4
Let x be the number and so it is: 3x-18
(x - 25)*4
15 - 2x
To express "125 decreased by a number" in algebraic form, you can use the variable ( x ) to represent the unknown number. The algebraic expression would be written as ( 125 - x ). This indicates that you are subtracting the value of ( x ) from 125.
