It's said that the theory can not be proved because we can't peer that minutely into the fabric of space-time. However here is a thought. If nanos prelacate smaller & smaller versions of themselves...same in a human being...repairing/improving/regenerating/halting-revearsing the aging prosess/curing all illness...perhaps the nanos might one day "see" these strings..."PEER AT THE "FACE" OF GOD"?

If possible could u teach me step by step if not ok.

1. Solve for x: 2/5(10x – 3) + 3/5 = 1

2. You have a total of $6000 invested in two accounts. One account pays 5% per year; the other pays 4% per year. If you earn a total of $250 this year, how much as invested in each account?

3. Solve: |5x – 2 | - 3 = 1

4. If a line has an x-intercept of -2 and y-intercept of 3, what is its slope?


5.Write in slope intercept form: 3x – 7y = 7

6. Let f(x) = 4x – 1 and g(x) = 1 – 2x2. Find (f/g)(2).

7. Solve by addition:
3x + 2y = 6
x + 2y = 4

8. Solve the system:
x + y + z = 5
x - y + z = -2
2x + y - z = 4

9. Solve for x:
| x 2 |
| 6 2x| = 10x

10. Use Cramer’s rule to solve:
-5x + y = 6
3x – 2y = 3

Well we all SHOULD know that elements from Manganese down to Hydrogen combine to create energy and all elements from Cobalt up decompose to create energy. All this ends at Iron. So how does Iron create nuclear energy? Does it combine or does it decompose?

Here is my other question im have problems with i dont exactly understand how to do this one:

In a college, some courses contribute more towards an overall GPA than other courses. For example, a science class is worth 4 points; mathematics is worth 3 points; History is worth 2 points; and English is worth 3 points. The values of the grade letters are as follows, A= 4, B=3, C=2, D=1, F=0. What is the GPA of a student who made a “C” in Trigonometry, a “B” in American History, an “A” in Botany, and a “B” in Microbiology?


2.59
2.86
3.08
3.33
3.67
