If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
If the number is x then the expression is: 2x+8
The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
Let the number be x and so the expression is: 2x+17
If you have a number x, then twice that number is 2*x and so the expression means 42 - 2*x
2(x - 7) = 8

If the number is x, then abs(8-x) or |8-x|
46
2x/8; x = the number
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
The difference between a number x and twice y is equal to fifteen.
2x-8
n-8
24
x - (8 - x)
If the number is x then the expression is: 2x+8
