expeople1 [14]
There are many different types of equations we can use to allow x to equal 19! Below are some examples :) See if you can come up with some on your own based off of these examples:

5x = 95.....................................Divide both sides b 5

x = 19.......................................There's one for you :)

_____________________________________________________________

1 + x - 5 = 15............................Combine like terms

x - 4 = 15..................................Add 4 to both sides

x = 19
_____________________________________________________________

There's just a couple of examples, but see if you can come up with some on your own and let me know if you get stuck!

Thank you for your question! I hope this helped! Have an amazing day and feel free to let me know if I can help you any further! :D

plug in 10 for x you get 50. 120-50=70

Hope this helps!

Jennifer used 0.42 gallons of paint to completely cover a square wall with an area of 168 square feet. Which measurement is clos
Marina86 [1]

Answer:

The answer to this question is: 12.96 ft ≈ 13 ft

Step-by-step explanation:

Data

Area 168 ft²

Length = ?

Volumen = 0.42 gallons

But we do not need the volume of paint because we know that the wall is squared-shape.

Only we need to know the formula to obtain the area of an square.

Formula   area = length²

So            168 = length²

Finally      √168 = length

             length = 12.96 ≈ 13 ft
