A number y decreased by 1 is equivalent to which of the following expressions?
y - 1
y = 1
y + 1
It is: 9+x
1/2 (x+y)
x+7=y
10 + 3x
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)
As an algebraic expression it is: 9-x
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)
