Kimberly needs $45 to go to the amusement park. She has $13. She earns $8 per hour working at her job. The equation 8h + 13 = 45 shows this relationship. How many hours does Kimberly need to work to earn enough money to go to the park?

Step-by-step explanation:

Given equation is 8h + 13 = 45

Where h is number of hour

So 8h=45-13

8h =32

h= 4 hour is the answer

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
