From the set {-252, -64, 64}, use substitution to determine which value of x makes the equation true.
1 answer:
9514 1404 393
Answer:
x = 64
Step-by-step explanation:
I find it easier to solve the equation, which requires 1 operation. Substituting 3 numbers requires 3 operations, so is 3 times the work. (I'm basically lazy.)
4x = 256 . . . . given
x = 256/4 = 64 . . . . the last of the listed values
__
Alternatively, you can let a graphing calculator or spreadsheet try the list of values for you. That result is attached.
_____
Since you know the rules of signed multiplication, you know that x must be positive. Only one answer choice is positive, so you really only need to try one number.
4(64) = 256 . . . . true, so x = 64
