Answer:
x=-5
Step-by-step explanation:
x+12=7
Subtract 12 from each side
x+12-12=7-12
x = -5
PEMDAS is the correct order of operations... parentheses, exponents, multiplication, division, addition, and subtraction.
Let's do Holly first
6 x (24/2)^2= first the parentheses
6 x (12)^2 = now exponents
6 x 144 = and multiplication
864
Now Jim
6 x 24 / 2^2 = exponents first
6 x 24 / 4 = next multiplication
144 / 4 = now division
36
So, Jim's expression is 828 less than the other expression
(864 - 36 = 828)

Answer:
can also be expressed as a ratio of two integers.
Step-by-step explanation:
Assume x and y are rational number, then x and y can be written as:
, where a and b are integers and b≠0
, where c and d are integers and d≠0
Then,
= 
= 
Since the set of integers are closed under multiplication, a*d is also an integer. Similarly b*c is also an integer.
can be expressed as a proportion of two integers, provided that y≠0. From this we can conclude that is a rational number, which concludes that the set of rational numbers are closed under division.
