Quetion to represent each problem the sum of 15 and six times a number tea is 80 one what is the number

11

Step-by-step explanation: The sum of 15 and six times t will be 15 + 6t = 81.

Now, you subtract 15 from both sides to isolate the constants from the variables on the left side and on the other side and you will end up with 6t = 66. Then, you divide 6 from both sides to finally isolate the numbers from the variable and 66 divided by 6 would equal 11

Hope this Helps :)

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
