Answer:

x = 2

Step-by-step explanation:

Change the right side so that it is in base 3 notation:

3^(3x - 2) = 81 = 3^4

Now both sides have the same base, we can now solve the following:

3x - 2 = 4 ---> x = 2

Answer:

Equation : $\frac{5}{7}x = \frac{5}{4}$

Gallons needed = $1\frac{3}{4}$ gallons

Step-by-step explanation:

It is given that:

Gallons of paint used by Tyler = $1\frac{1}{4} = \frac{5}{4}$

Area of fence painted = 5/7

Let,

x be the whole fence needed to paint.

$\frac{5}{7}x = \frac{5}{4}$

Because we know that 5/7 of the fence is painted with 5/4 gallons of paint.

Multiplying the equation with 7/5

$\frac{7}{5}*\frac{5}{7}x=\frac{5}{4}*\frac{7}{5}\\x= \frac{7}{4}\\x = 1\frac{3}{4}$

Therefore,

Equation : $\frac{5}{7}x = \frac{5}{4}$

Gallons needed = $1\frac{3}{4}$ gallons
