Evaluate each expression if x=4,y=2/3 and z=1/4

22.3/8x
12/8=1 1/2

24.3x=12

26.9y=36

28.yz=2/12=1/6

30.xyz
Im not sure

26 is wrong.

28.

4/1 * 2/3 * 1/4 = 8/12 = 2/3

Thank you Ms.Sue, that helped a lot. :D

You're welcome, Jerald.

To evaluate the expression 30.xyz, you need to substitute the values of x, y, and z into the expression.

Given that x = 4, y = 2/3, and z = 1/4:

30.xyz = 30 * x * y * z

Substituting the values:

30 * 4 * (2/3) * (1/4)

= 30 * (8/3) * (1/4)

Next, divide the numerator and denominator of each fraction separately:

= (30 * 8 * 1)/(3 * 4 * 4)

= 240/48

= 5

So, the value of the expression 30.xyz, when x = 4, y = 2/3, and z = 1/4, is 5.
