twice a number can be 2x and six less than it is 2x-6.
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
The additive inverse of 18 is -18. The additive inverse of any number is the opposite of that number, such that the sum of the original number and the additive inverse is zero.
2x+4y
The difference between a number x and twice y is equal to fifteen.
4 + 2*n ≥ 20
4*m/5 + 18
4m/5 + 18
twice a number can be 2x and six less than it is 2x-6.
If the number is n, then twice the number is 2n and the sum of the two is n + 2n = 3n.
118
Eighteen
4*(2x + 8) = 32
970.
This is an algebraic expression. It can be written as 3(2x + 4)
