What is the value of x/yz if x= -2, y= -3, and z= -4?
A. 6
B. -6
C. 1/6
D. -1/6
I have no idea how to work this out. Can someone walk me through this?
Substitute numbers for letters.
x/yz if x= -2, y= -3, and z= -4?
-2 / (-3 * -4) = ?
Right.
Ohhh... It's -1/6 right?
Because I multiplied -3 and -4 and got twelve, and divided by 2 and got -1/6.
To find the value of "x/yz" when x = -2, y = -3, and z = -4, you can substitute these values into the expression and perform the calculations. Here's how to do it step by step:
1. Start with the expression "x/yz."
2. Substitute x = -2, y = -3, and z = -4 into the expression.
So, "x/yz" becomes "-2/(-3)(-4)."
3. Simplify the expression inside the parenthesis:
-3 * -4 = 12.
The expression now becomes "-2/12."
4. Simplify the expression further by reducing the fraction:
Both -2 and 12 can be divided by 2:
-2/12 = -1/6.
5. Therefore, the value of "x/yz" is -1/6.
So, the correct answer is D. -1/6.
