Want this question answered?
the letter in 2x+6. The variable is the x.
6*(3+20) = 138
It is a linear expression with one variable, b. Since it is not an equation it cannot be solved.
A constant is a number which is fixed in an question. On the other hand, a variable is a number which can change. In your expression, 6 + axb, you have 1 constant (6), and 3 variables (a,x, and b). Hope this helps :)
X+6. Variable (x)
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
Which phrase describes the variable expression 6.w
The coefficient in an expression is the multiplier of the variable in the equation. Here, the coefficient would be 6.
