Solve the equation below for m.
3 (0.3m + 6) + m = 75

m=30

Step-by-step explanation:

3 (0.3m + 6) + m = 75

Distribute the 3

.9m + 18 +m = 75

Combine like terms

1.9m +18 = 75

Subtract 18 from each side

1.9m +18-18 = 75-18

1.9m = 57

Divide each side by 1.9

1.9m/1.9 =57/1.9

m = 30

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!
