Perimeter = 2(W+L) = 80
W + L = 40
W = 4
L = 36
so length = 36 cm
Answer:
21 monkeys
Step-by-step explanation:
The ratio is 3:7 so 3*3=9 lions 7*3=21 monkeys
9+21=30
Via Comparison method
2x-3 = -x+3
->
3x=6
->
x=2
Replacing X with 2 in the equations to find your Y
2(2)-3 = 1
-2+3 = 1
So:
X: 2
Y: 1
