x=y-8
z=x+12
An number with a x after mean multiply, so it would be 4x12=48
Though 10x +24 is an expression and it can not be evaluate, we can write 10x+24=2 • (5x + 12)
That will depend on the plus or minus value of 12 which has not been given.
2b + 3 b = 12 . 27 since the beginning is 2 x 12, which equals 24, and then you have to add the extra 3.
12 divided by 4=3

The commutative property.
You take the expression and, wherever there is the variable n in the expression, you substitute 12. Wherever there is m, you substitute 4. Then you evelaute the expression.For example n2 - 2mn + 27m = 122 - 2*4*12 + 27*4 = 144 - 96 + 108 = 156
12 - 10 + 4 = 6
12 + 5 equals...
When you evaluate it and round the answer to the nearest whole unit you will find that the answer is 12 provided that you have done it correctly.
Constant values are expressions as well, still I don't think they are so hard to evaluate... well, in this case it is twelve
Neither of the two is correct. It would be 12 inches equals a foot or 144 inches equals 12 feet.
There is no variable in (8x12)+8, so it would be called an arithmetic expression. It would evaluate to 96+8 = 104.
6 + 12 - 5 = 13
