7 + nothing is 7

9 + 5 = 14, bring down your 4 carry your 1

8 + 6 = 14 plus the 1 you carried is 15

Just make sure you keep the decimals lined up.

{0.23,19%1/5} Order each set of numbers from least to greatest show work

Answers

First you have to change them all to the same form, so you have to pick one out of them, so for instance you could pick percent which would be; 23%, 19%, and 20%, so from least to greatest it would be; 19%, 20%, and 23%. Hope this helps!

Can someone please show how to solve this ln(5x-1)+ln(x-6)=ln6 ???

Answers

when you add ln, you multiply
ln((5x-1)(x-6)=ln6  do now FOIL
ln(5x^2-30x-x+6)=ln6
therefore
5x^2-31x+6=6 and 
5x^2-31x=0 furthermore 
x(5x-31)=0
one solution is 0, which we will reject
the other solution is 5x=31
x=31/5
ln(5x - 1) + ln(x - 6) = ln(6)
ln((5x - 1)(x - 6)) = ln(6)
            ln(5x(x - 6) - 1(x - 6) = ln(6)
ln(5x(x) - 5x(6) - 1(x) - 1(-6)) = ln(6)
ln(5x² - 30x - x + 6) = lm(6)
ln(5x² - 31x + 6) = ln(6)
     5x² - 31x + 6 = 6
5x² - 31x + 6 - 6 = 6 - 6
     5x² - 31x + 0 = 0
x = -(-31) +/- √((-31)² - 4(5)(0))
                       2(5)
x = 31 +/- √(961 - 0)
                 10
x = 31 +/- √(961)
              10
x = 31 +/- 31
           10
x = 31 + 31    x = 31 - 31
          10                  10
x = 62             x = 0
      10                  10
x = 6²/₅            x = 0
