The algebraic expression for the sum of x and 9 is x + 9. In this expression, x represents a variable that can take on any value, and 9 is a constant. When you add x and 9 together, you are combining the variable x with the constant 9 to get the sum. This expression can be simplified further if needed, but the basic form is x + 9.
1/2 (x+y)
x+7=y
The algebraic expression that represents the sum of 10 and 3 times a number x is 10 + 3x. This expression can be simplified by multiplying 3 with x to get 3x, and then adding 10 to it. In this expression, 3x represents three times the value of x, and 10 represents a constant value added to the product of 3 and x.
Write the following as an algebraic expression using x as the variable: The sum of a number and -8
It could be: -3/8+4x-9z as an algebraic expression
Assuming the number is x, then: x + 9
9*(x+ 2)
x times the sum of x and 9 x times (x times 9) x(9x) 9 times x[squared] 9x[squared]
21+x
x + 21
X+9
(x+5)/3
x+(-8)This simplifies to x-8
4*(x - 8)
1/2 (x+y)
4(x + 5)
Because "x" is a variable, it is the same as 9 times x.
