Im pretty sure that the answer to that is 5-9m+n
This is the concept of algebra, suppose that the number of cats is x;
number of cats will be x-20
number of rabbits will be 3/2x
thus the total number of animals will be:
x+(x-20)+3/2x=350
7/2x=350+20
7/2x=370
x=370*2/7
x=105.7=106
therefore we conclude that there we 106 cats in the shelter
Answer:
C. 29 cm
Step-by-step explanation:
- <em>We need to use The Triangle Inequality Theorem, which states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.</em>
<u>Now let's compare the given measures vs answer choices.</u>
So, we have legs of 13 cm and 17 cm
Sum of two legs equal to 13 cm+ 17 cm= 30 cm
Now, the answer options:
--------------
No, as 31 cm> 30 cm, one leg is greater than sum of other two legs, which is not possible
--------------
No, as 13 cm + 4 cm = 17 cm, sum of two legs equal to third leg
--------------
Yes, as 29 cm < 30 cm and the other pairs of legs, when summed up give greater number than the remaining leg.
- 1. 13+17 > 29
- 2. 13+29 > 17
- 3. 17+29 > 13
--------------
No, as 30 cm is equal to sum of other legs
--------------
As we found out, the answer is C. 29 cm
Hope it makes sense now
