units
Step-by-step explanation:
The Line 1 has equation x + y = 5 ....... (1) , and
Line 2 has equation x + y = 3 .......... (2)
Now, we have to find the perpendicular distance between line 1 and line 2.
We can say that (3,0) is a point on line 2 as it satisfies the equation (2).
Now, the perpendicular distance from point (3,0) to the line 1 will be given by the formula
units (Answer)
We know that the perpendicular distance from any external point () to a given straight line ax + by + c = 0 is given by the formula

There are 138 female patients in the hospital.
<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
