2 x 10^4 x 2 x 10^4 x 2 x 10^4 = 8 x 10^12 8,000,000,000,000
(4 - 3) x 10 x 12 - 5 = 115.
x = 4
0.0004 = 4 x 10-41 pico... = 1 x 10-124 x 10-4/1 x 10-12 = 400 million of them
I assume you mean, ( parentheses!!!) X/2 + 4 = 10 multiply through by 2 2/1(X/2 + 4 = 10)2/1 X + 8 = 20 subtract 8 from each side X + 8 - 8 = 20 - 8 X = 12 ------------------check in original equation 12/2 + 4 = 10 6 + 4 = 10 10 = 10 ----------- checks
2 x 10^4 x 2 x 10^4 x 2 x 10^4 = 8 x 10^12 8,000,000,000,000
(4 - 3) x 10 x 12 - 5 = 115.
7-10 = -3 4 x 3 = 12 12 + -3 = 9
16 x -4 = 12
If I understand the question correctly, you require x such that 4+x:10+x = 12+x:24+x. The answer is x = 12.
-4
x = 4
4.20 * 107 * 2.5 * 10-12 = 10.5 * 10-5 = 1.05 * 10-4
60. 10 x 6 = 60, 12 x 5 = 60, and 15 x 4 = 60.
12C4 = (12!)/[(12 - 4)!4!] = (12!)/(8!4!) = (12 x 11 x 10 x 9 x 8!)/(8! x 4 x 3 x 2 x 1) Simplify 8! with 8!, 12 with 4 x 3, 10 with 2 = 11 x 5 x 9 = 495 Or you can use the graphing calculator: press 12, MATH, go with the right arrow to PRB, press 3 for nCr, ENTER
-10
3/4 x 10/10 = 30/40 3/10 x 4/4 = 12/40 so 3/4 is larger
