Question

What is the solution of log3x −725 = 2?

x = −2

x = 2

x = 3

x = 4

Answer 1

Are you sure it;s 7^25?? o-o

Answer 2

thats a huge number!

Answer 3

It is log 3x-7 those are supposed to be subscript and then the 25 is a whole # and then says =27

Answer 4

what is the base of the log....

and is the question

log(3x - 725) = 2

Answer 5

I can't be log(3x) -725 = 2

Answer 6

log(3x - 725) = 2 is possible yes

Answer 7

its a small 7 normal 25 not 725 ok

Answer 8

I guess the base is 10

Answer 9

small 7 ?

Answer 10

ok... so the base of the log is (3x-7) and the number is 25

so you are dealing with a base 5 log

since 25 = 5^2 and the base of 5 wll result in an answer of 2

so you are solving

3x - 7 = 5

so just solve for x

Answer 11

and the answer is in the list of choices.

Answer 12

this is why

\[\log_{5}(25) = \log_{5}(5^2) = 2\]

Answer 13

I'm nor sure if Latex is working

Answer 14

It's no :P

Answer 15

not*

Answer 16

Really a problem on a math site

Answer 17

ok.. so reading the information

the base of the log is 3x - 7

to take the log of 25 and get an answer of 2

then base has to be 5

so as I said before,

solve 3x - 7 = 5

Answer 18

can you show what happened to the 27 on the other side of the equal sign

Answer 19

The value of a dirt bike decreases by 20% each year. If you purchased this dirt bike today for $500, to the nearest dollar how much would the bike be worth 5 years later?

$84

$119

$164

$222

Answer 20

here is the solution and reasoning

Answer 21

and 27 doesn't exist in the question...

Answer 22

and the other question simply requires you to use the compound interest formula..

good luck
