P = 11 + 4 + 18 + 37 + 7 + 19 = 96
a = (18*7) + (11*19) = 126 + 209 = 335
<span>As of January 8, 2015, the U.S. is $18.1 trillion in debt. (Source: National Priorities Project)
1 Trillion
= 1 Thousand Billion
= 1,000,000,000,000
= 10</span>¹²

U.S National debt currently stands at:
$ 18.1 x 10</span><span>¹²

*What information would be lost? Well firstly the 0's. The 0's put the size of the number into perspective. The word "trillion" would also be taken out of the picture, once again altering the perspective of the number.
Personally I'd prefer to hear "18.1 Trillion Dollars". Sounds more interesting.

Like terms are terms that have the same variable no matter the coefficient value such as a negative or positive coefficient (number right to left of the variable aka the letter representing an unknown amount of value).
A. 8n : - 4n becuase the have the same variable (N)
B. - 2d: D because they have the same variable and even if d has no coefficient, it still has value, variables with no coefficient always equal 1 no matter the circumstances
C. - b: 17b and -3b2 because they both have the same variable eliminating the coefficients being two different types of numbers (positive and negative). The expressions have to have the same variable.
D: 4y², -3y2,4y, and 4 to the second power. This is because they all have the same variable.
E. 6x2y: 3xy because the variable are specifially xy and they must be in order to be like terms.
abc: all because they have all the letters but are just in different orders of variables. (thats all)
7x12=84, plus 1 equals 85.
85/12=7, remainder of 1.
The answer is 85.
To answer this first we will subtract d amount of dollars Boy had by d amount of dollars he had left in d end. den we will divide d amount of dollars he used by d amount of books he bought. den d answer will be d amount of money each book cost. Lets do it:-
$266 - $18 = 248
$248 ÷ 6 books = 41.33333.....
So, 1 book costs about 41.50.
Hope I helped ya!! xD
