I don’t get number 5, could someone explain to me the answer?

55

Step-by-step explanation:

I used some graphing software. I changed 33 and 44 to 3 and 4 just for the sake of saving space. So the diagonal measurement is represented by segment BD. So since I divided 33 and 44 by 11 to make it smaller to get 3 and 4, I am going to multiply 5 by 11 to get 55

Thus the REAL diagonal measurement of the TV screen is 55 inches

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
