The total number of DVDs that she bough is 6
<h3>Linear equations</h3>
Linear equation are expression that has a leading degree of 1.
Let the price of each DVD be x such that if Grace bought a television for $329 and some DVDs for $5.75 each and spent a total of $363.50, ten;
329 + 5.75x = 363.5
Subtract 329 from both sides
329 + 5.75x - 329 = 363.5 - 329
5.75x = 34.5
x = 34.5/5.75
x = 6
This shows that the total number of DVDs that she bough is 6

Answer:
x = 10
y = 70
Step-by-step explanation:
By using the vertical angles theorem we know that x+ y +10 = 90, also simplified to x + y = 80
and 2x + y = 90
By using the substitution method on x + y = 80, it will be y = -x + 80
When you put into the equation 2x + y = 90 you will get 2x -x +80 = 90
Then it will simplify to x = 10
After that plug 10 into x + y = 80 to 10 + y = 80 and get y = 70
