Answer:

5 2/3 hours  

Step-by-step explanation:

We can use a ratio to solve this problem

hours over money


4.5 hours         x hours

-------------    =  ------------

27 dollars        34 dollars


Using cross products

4.5 * 34 = 27 * x

153 =27x

Divide each side by 27

153/27 = 27x/27

5.666666 hours

(3x+4)^3=2197 solve this equation
Burka [1]
(3x + 4)³ = 2197

Taking the cube root in this case is easier, although we can do it the extended way which is complicated.

\sqrt[3]{(3x+4)^3} = \sqrt[3]{2197}
3x + 4 = 13

Now solve normally.

subtract 4
3x + 4 = 13
       -4    -4

3x = 9
Divide by 3 to isolate 3

\frac{3x}{3}  =  \frac{9}{3}
3 and 3 cancels out

x = 3
