Please show steps on how to solve <br> log7 -2b-9=-6

NeTakaya

Answer: b= - -log10(7)+3/2

Step-by-step explanation: log 10 (7) -2b-9=-6 : b= - -log10(7)+3/2 (Decimal : b = -1.07745...)

so these are the steps how I got it I did log 10 (7)-2b-9=-6 subtract log 10 (7) -9 from both sides log 10 (7)-2b-9-(log10(7)-9)=-6-(log 10 (7) -9)

Simplify -2b= -log10(7)+3

Divide both sides by -2 -2b/2= - log 10(7)/-2+ 3/-2 if you simplify it should give you b= - -log10(7)+3/2 that should be your answer but i'm not sure those I think that's how you do it let me know if you got it right bye!

Mr. Ravenhead's car averages 23.75 miles per gallon of gasoline. Express this amount as a mixed number in simplest form

lisabon 2012 [21]

A mixed number consists of a whole number and a fraction.

23.7523 will be the whole number.
0.75 will be the fraction.

To convert 0.75 into a fraction, set it over 100 and simplify.

$\frac{75}{100} = \frac{75:25}{100:25} = \frac{3}{4}$

$23 \frac{3}{4}$
