X will be the speed of species b and 4x will be the speed of species a:
x + 4x = 180
5x = 180
x = 180 / 5
x = 36 m/h
If species b has a speed of 36 m/h, the speed of species a is 4 times that:
4 x 36 = 144 m/h.

22 centimeters
242 ( area ) divided by 11( width) =22 ( length)
Answer:
base =7.6 cm
Step-by-step explanation:
area of a triangle =base * height/2
=11.02*2 =base *height
22.04=base *2.9
22.04/2.9 =base
7.6 =base
Answer:
??
Step-by-step explanation:
Solving by substitution:
y = 4x - 3
2x + 7y = 41
Let us substitute the first equation y = 4x - 3 into the second.
2x + 7y = 41
2x + 7(y = 4x -3) = 41
2x + 7(4x -3) = 41
So that's the third option.
I hope this helps.
