13 + 3 5/9 = ? the only answers available are-9 4/9-10 11/15-7 1/2

- 13 + 3 5/9

-10 + 5/9

-90/9 + 5/9 = -85/9 = -9 4/9.

If you have further questions, ask me

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
