I have the same class and, to be honest, this is the only one I got correct! The answer is pomposity.

Answer:
In step 4, Jim's answer is incorrect.
Step-by-step explanation:
In step 1, Jim swaps the order of addends using the commutative property of addition.
In step 2, Jim uses the distributive property to factor -1 from the final two terms. (The associative property lets Jim move parentheses.)
6.1 +(-8.5 -1.3) . . . associative property
6.1 +(-1)(8.5 +1.3) . . . distributive property
In step 3, Jim has used the properties of real numbers to form the sum of two of them.
In step 4, Jim wrote an answer of 1.1, when the answer should have been -3.7. Jim's answer is incorrect.

The descriptive statements about steps 2 and 4 are both true.
(w-2)(w-2) -2w*w=-2w^2 w*-2=-2w =-4w w^2-4w+4
Answer:
Step-by-step explanation:
We are given a ratio for this problem so we will use the formula for when we are given a ratio (as opposed to the formula for when you are given that the point you're looking for is a fraction of the way from one point to another, like 1/3 of the way from point A to point B. That's a different formula).
The formulas are for the x and y coordinates of the point in question:
and 
where
a = 3 (from the ratio),
b = 1 (from the ratio),
x1 = -4, y1 = 0 (from point J)
x2 = 0, y2 = 4 (from point K). Filling in for x first:
gives us
and now for y:
gives us
Therefore, the coordinates that partition that segment into the ratio of 3:1 are (-1, 3)
You did not specify the brother's age, so I make a expression, <em>b</em> as the variable.
(3<em>b</em> + 5) - 11
Now do that with the brother age instead of the variable.
