Step-by-step explanation:
You've got the concept correct, but be careful with your parentheses. You should write it 3/(2n). Otherwise it looks like three halves n.
Answer:
A. 100
Step-by-step explanation:
Answer:
x = 2.13 × 10^11
Approximately 2.13 × 10^11 mails were processed in 2006
Completed question;
There were approximately 1.6 * 10^11 pieces of mall processed by the United States Postal
Service in 2012. This is about 75% of the number of pieces of mail processed in 2006.
Approximately how many pieces of mail were processed by the United States Postal Service in
2006
Step-by-step explanation:
Let x represent the number of mails processed in year 2006
Given;
Number of mails processed in 2012 N = 1.6 × 10^11
Number of mails processed in 2012 N is about 75% of the number of pieces of mail processed in 2006.
So;
N = 75% of x
N = 0.75x
x = N/0.75
x = (1.6 × 10^11)/0.75
x = 2.13 × 10^11
Approximately 2.13 × 10^11 mails were processed in 2006
2 pounds.
60(20) = 1200 = area
If 300 square feet requires 1/2 pound, you can divide 1200 square feet by 300 square feet.
1200/300=4
4 times 1/2
4(1/2)=2
For every 300 square feet, you need half a pound. If you were to have 600 square feet, you would need a pound of grass seed. Therefore, for 1200 square feet, you need 2 pounds of grass seed.
Answer:
Explanation:
7. f(x) = x^4 + 3x^3 - 6x^2 - 10x + 8
f(2) = 2^4 + 2^3 - 6^2 - 10(2) + 8
f(2) = 16 + 8 - 12 - 20 + 8
f(2) = 0
8. x^2 - 9 = (x - 3)(x + 3)
x ^2 + x - 6 = (x + 3)(x -2)
Thus, the common factor is x + 3
