If we have 300 animals total, and the ratio of cats to all animals is 7 : 15 or 7/15, we can multiply that fraction/ratio by the total, so 300 * 7 /15 = 20 * 7 = 140.
Answer:
the room is -1m by 14m
Step-by-step explanation:
what you do to find it is first find x.
the perimeter is 26, and one side is 15 meters longer than the other(twice).
So the equation is:
x + (x + 15) + x + (x + 15) = 26
2x + 2(x + 15) = 26
2x + 2x + 30 = 26
4x + 30 = 26
26 - 4x = 30
26 - 26 - 4x = 30 - 26
-4x = 4
-4x/-4 = 4/-4
x = -1
Now we have two sides of the room. Now we want the 15m longer ones...
-1 + 15 = 14
so the dimensions are -1 by 14, or -1x14

Answer: I hope you understand, just mutiply whatever x is by 11 to get Y
Step-by-step explanation:
x = unknown number
9x+2x= 11x
Y=11x
