Answer:
x = 6
Step-by-step explanation:
move all terms to the left:
-1.5x+12-(2.5x-12)=0
get rid of parentheses
-1.5x-2.5x+12+12=0
add all the numbers together, and all the variable.
-4x+24=0
move all terms containing x to the left, all other terms to the right
-4x=-24
x=-24/-4 - divide
x=+6
So you express fraction.
15 x (1/3)^ 3=15/27=5/9
The mean is the average of a set of numbers, to find the mean, add all the numbers, then divide by the amount of numbers.
