So solve for x

|x-72.5|=4
the || makes the inside positive so it could be positivie and negative so

x-72.5=4 and x-72.5=-4
solve for x in both situations

x-72.5=4
add 72.5 to both sides
x=76.5


x-72.5=-4
add 72.5 to both sides
x=68.6


the minimum it can be set to is 68.5 and the max is 76.5

Divide 4 by 6. Easier if you write it as a fraction: 4/6 This can be reduced to 2/3.   This means that each person gets 2/3 of a pie equally.

Rewrite the following expression using the properties of logarithms. log2z+2log2x+4log9y+12log9x−2log2y
kramer
Use the rules of logarithm:
1. log(x)+log(y)=log(xy)
    log(x)-log(y)=log(x/y)
2. k*log(x) = log(x^k)
    log(x)/k = log(x^(1/k))

<span>log(2z)+2log(2x)+4log(9y)+12log(9x)−2log(2y)
=</span>log(2z)+log(4x^2)+log(9^4y^4)+log(9^12x^12)−log(4y^2)
=log(2z)+log(4x^2)+log(6561y^4)+log(282429536481x^12)−log(4y^2)
=log(59296646043258912 * x^14 * y^6 * z)
