Given:
The sum of three numbers is 212 .
The ratio of the first to the second is 13:16 and that of the second to the third is 2:3.
To find:
The unknown numbers.
Solution:
We have,
First : Second = 13:16
Second: Third = 2:3
We need to combine these ratios, to get a single ratio for all three numbers.
Second: Third = 2×8:3×8 = 16:24
Now,
First: Second: Third = 13:16:24
Let the first, second and third numbers are 13x, 16x and 24x respectively.
So, the numbers are,
Similarly,
And,
Therefore, the three unknown numbers are 52, 64, 96.
Answer:
One Solution:
Infinitely Many Solution:
No Solution:
Step-by-step explanation:
System 1
Hence only one solution
System 2
Both represents the same line. Hence these have infinitely many solutions.
System 3
Compare both the lines with , where m is the slope.
for both the lines.
Hence these two lines are parallel that means there does not exists any point of intersection
So this system will not have any solution.
