8 is subtracted from a number, and then the difference is multiplied by 2.the result is 24.find the number

20

Step-by-step explanation:

suppose the number is x

so

(x-8) * 2 =24

x-8=12

x=12+8

x=20

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!
