Here is the full question :
Arthur is organising his collection of DVDs He has 112 altogether. The ratio of comedy films to action to horror is 4 : 7 : 3
How many of each type of DVD does he have?
the number of each dvd arthur has = ratio / sum of ratios) x total number of DVDs
Sum of ratios = 4 + 7 + 3 = 14
Comedy films = (4/14) x 112 = 32
Action = (7/14) x 112 = 56
Horror = (3/14) x 112 = 24
Hi there !
Y = 7x - 53
Y = -4x + 35
I always used substitution to solve equations so we gonna use it here as well :)
-----------------------------------------------------------------------------------------------------
We gonna solve y = 7x - 53 for y
Let's start by substitute 7x - 53 for y in y = -4x + 35
y = -4x + 35
7x - 53 = -4x + 35
Common terms
7x + 4x = 35 + 53
11x = 88
divide both sides by 11
11x/11 = 88/11
x = 8
Now, since we have the value for x, it will be easier for us to find Y. So, we gonna use the value of x which is 8 to find y.
In order to find the value for y, we must substitute 8 which is the value for x in y = 7x - 53
y = 7(8)-53
y = 56 - 53
y = 3
The final answer is : X = 8 and Y= 3

The correct option is B
(8,3)

I hope that helps!
Answer:
x = 6
Step-by-step explanation:
Given that PQ = 3x + 14, QR = 7x - 10, and Q is the midpoint of PR, it means Q is equidistant from both endpoints of P and Q. In order words, the distance from P to Q is the same as the distance from Q to R.
Therefore, PQ = QR. Which is:
![3x + 14 = 7x - 10](https://tex.z-dn.net/?f=%203x%20%2B%2014%20%3D%207x%20-%2010%20)
Solve for x. Collect like terms
![3x -7x = - 14 - 10](https://tex.z-dn.net/?f=%203x%20-7x%20%3D%20-%2014%20-%2010%20)
![-4x = -24](https://tex.z-dn.net/?f=%20-4x%20%3D%20-24%20)
Divide both sides by -4x
![x = 6](https://tex.z-dn.net/?f=%20x%20%3D%206%20)
