Answer:
Step-by-step explanation:
For species A,
For species B,
When their populations are equal,
The diagram below shows the population of Species A overtaking that of Species B in about 30.5 yr.
Answer:
is the a. Perpendicular lines form 90° angles.
Volume of a cube = l^3, where l is the side length (note that the length, width and height in a cube are equal)
Volume of cube = 6^3 = 216 m^3
1/3 = 8/24
1/8 = 3/24
use 24 since it's the LCM of 8 and 3
8-3/24 = 5/24
Answer:
x=-2 y=3
Step-by-step explanation:
The substitution is basically given to you. Exchange x from the second equation with y-5
Once that is done and you combine the parentheses you get:
2y-10+y=-1
Add 10 on both sides of the equal sign
You get:
3y=9
Divide both sides by 3
You get:
y=3
To check your work you can substitute y in the second equation with 3 and solve it that way to get x=-2 (x equals negative two)
