01.2 times 10 to the second power minus 6 times 10 to the second power
1.2 x 10^2 - 6 x 10^2 =
120 - 600
-480
30 = 3 x 2 x 5
8 = 2 x 2 x 2
2 is the GCF
2*3^x=7*5^x rearrange as
(2/7) = (5^x / 3^x)
(2/7) = (5/3)^x take the log of both sides
log(2/7) = log(5/3)^x and we can write
log(2/7) = x log(5/3) divide both sides by log(5/3)
log(2 / 7) / log (5/3) = x ≈ -2.45
{(0,1), (1,-3), (2,-4), (-4,1)}
Domain = {0, 1, 2, -4}
Range = {1, -3, -4, 1 }
Since these numbers have no factors in common, the Least Common Multiple = 22 x 7 = 154
2,2,3,5
Here's my best guess !!!!
(2 * 5)^(3^2) =
10^9 =
one billion
2x+40=(2/11)x multiply through by 11
22x + 440 = 2x subtract 22x from each side
440 = -20x divide both sides by -20
-22 = x
C(8,3)*(.45)^3*(.55)^5 = about 25.68%
Here are some examples explaining this proceedure :

24 stools x (7/8)lb/ stool = 24*7/ 8 = [24/8] *7 = 3 * 7 - 21 lbs.
