<span>Let us start with the schnauzers, the easiest one to imagine. Let us assume that there were x number of schnauzers.
Scottie's are 3 more than schnauzers. So their number is x+3
Wire haired terriers are 5 less than twice the number of schnauzers.
So their number is 2x -5 (2x for twice the number of schnauzers)
Now add all these numbers.
That is x + x+3 + 2x-5 = 4x -2
The total number of dogs, 78, is given in the question
Now we know that 4x -2 =78
4x = 78 +2
= 80
Therefore x = 80/4
= 20.
So there were 20 schnauzers, 23 Scottie’s and 35 wire haired terriers</span>
For this case, we have that by definition, the circumference of a circle is given by:
![C = \pi * d](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20%2A%20d)
Where:
d: Is the diameter of the circle given by 2r, that is, twice the radius.
If we have a circle with a diameter equal to 8cm, then the circumference is given by:
![C = \pi * 8 \ cm](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20%2A%208%20%5C%20cm)
ANswer:
Option C
![8 \pi \ cm](https://tex.z-dn.net/?f=8%20%5Cpi%20%5C%20cm)
1. X + 5
2.15-15
3. C= ( 3x9.95)+(2x14.98)
4.?
5. 12,000+500x ?idk
