10x - 3y + 2x
1. Andre says that 10x + 6 and
5x + 11 are equivalent because they both equal 16 when x = 1.
Do you agree with Andre?
Yes, I agree with Andre
No, equivalent expressions are equal no matter what value you plug in for the variable. When you plug in 0, these expressions are not equal.
2. Select ALL expressions that can be subtracted from 9x to result in the expression
3x + 5.
9x - (EXPRESSION)
a) -5 + 6x
b) 5 - 6x
c) 6x + 5
d) 6x - 5
e) -6x + 5
3. Select ALL the statements that are true for any value of x.
a) 7x + (2x + 7) = 9x + 7
b) 7x + (2x - 1) = 9x + 1
c) 3x + (10 - 3x) = 10
d) 5x - (8 - 6x) = -x - 8
e) 4x - (2x + 8) = 2x - 8
f) 6x - (2x - 4) = 4x + 4
