Gia got some books from Library yesterday she got five books today Gia returned three books Gia has six books how many books did
makvit [3.9K]

Answer: 4


Explanation:


You can write an algebraic expression to represent the sequence with the books in this way:

  • yesterday she got five books: 5
  • today returned three books: - 3
  • how many books did Gia have to begin: n
  • At the end she has six books, which means that you can set an equality:

       n + 5 - 3 = 6

Now you follow these steps to clear the unknown:

  • do the operations in the left side: n + 2 = 6
  • use subtraction property of equality: n = 6 - 2
  • do the operations: n = 4

And that is the number of books whith which Gina started: 4

What is the height of the tv and is it square inches or inches ??
fiasKO [112]
To find the height of the TV you first need to realize that the question is giving you dimensions for a triangle. 

Every triangle has a hypotenuse and two sides. To find the hypotenuse you square both sides, add them, and then square root. So to find one of the sides you get the hypotenuse, square it, and subtract the square length of the given side. 

The equation is 25^2-20^2.
Which if simplified is 625-400, the then solution is going to be 225. 
You next will square root 225, 225^(1/2). Which your answer should be 15 inches for the missing side length.

What is the velocity of a wave with a frequency of 930 Hz and a wavelength of 0.50 m
erma4kov [3.2K]
Hi, thank you for posting your question here at Brainly.

To find the velocity of light or any electromagnetic wave, we use the equation: v = wavelength * frequency. Substituting,

v = 0.5 m * 930 1/s
v = 465 m/s
