Step-by-step explanation:
One of the logarithm rules states the following:

For this problem, that means the following:

So now we have the following:

Rolling the log, we get the following:

= 98 2/3
= 98 + 2/3
= 98/1 + 2/3
= (98/1 * 3/3) + 2/3
= 294/3 + 2/3
= 296/3
= 296 ÷ 3
= 98.666667
We can make two simple equations to express their ages to each other, then solve for one of the variables. Let n be Nojo's age and j be Jacob's age.
n(j) = 84
n - 5 = j
Use substitution to get only one variable in an equation.
n (n - 5) = 84
n^2 - 5n = 84
Since we have n to the power of 2, this equation has two possible answers, but since we are given four possible answer, just substitute them in the equation until one makes the left side equal 84.
<span>n^2 - 5n = 84
</span>12^2 - 5 (12) = 84
144 - 60 = 84
84 = 84
The answer is C = 12
The unit rate is 2 paintings per hour.
1 + (-5) becomes 1 - 5 because you are adding a negative number.
1 - 5 is -4
