Answer:
see below
Step-by-step explanation:
4 ^(3x-1)=3
Take the natural log of each side
ln(4 ^(3x-1))= ln (3)
We know that ln ( a^b) = b ln a
(3x-1) ln 4 = ln 3
Divide each side by ln 4
3x-1 = ln(3)/ (ln4)
Add 1 to each side
3x = ln(3)/ ln (4) +1
Divide by 3
x =1/3 [( ln 3)/ ln (4)] + 1/3
x = .792461
6 and 3/4 divided by 1/2
27/4 divided by 1/2
27/4 * 2/1 = 27/2 = 13 and 1/2
4/5 recommend, so about 4/5(120) = 96 doctors recommend the brand.
Answer:
$9
Step-by-step explanation:
If you do 13x1.50= 19.5
28.50 - 19.5 = 9
Answer:
Step-by-step explanation:
hello,
first of all we will study the quadratic expressions
we can write that, (the different answers provide good clues :-) )
and
so first of all as we cannot divide by 0 we need to take x different from 7, -12 and -30 and then we can write
hope this helps
