<h3>Solving word problems involving ratios.</h3>
The solution to the word problem involving ratios in the given problem can be determined as follows.
From the given information:
The total number of people in the hospital = male + female
= 184 + x(unknown)
- If the ratio of male to female is 4: 3.
- The total ratio is 4+3 = 7
The ratio of males in the hospital is:


x = 322
The number of female patients in the hospital can now be computed as:

= 138 female patients
Check:
The total number of people in the hospital is:
= 184 + 138
= 322 patients

Our final answer can't be a decimal, so we round it to:
Answer:
x=2, y = -8
Step-by-step explanation:
y=-2x-4
y=2x-12
-----------------
Subtract the two equations
y=-2x-4
-y=-2x+12
-----------------
0 = -4x +8
Subtract 8 from each side
-8 = -4x+8-8
-8 = -4x
Divide by -4
-8/-8 = -4x/-4
2 =x
Then solve for y
y = -2x-4
y = -2(2) -4
y = -4-4
y = -8
A^2 + b^2 = c^2....a and b are the legs and c is the hypotenuse
2^2 + b^2 = 4^2
4 + b^2 = 16
b^2 = 16 - 4
b^2 = 12
b = sqrt 12 <=== square root of 12 units
