Answer:
8 crabs and 2 octopi
Step-by-step explanation:
Let c represent the amount of crabs and o represent the amount of octopi.
We can use this to set up a system of equations:
6c+8o=64
c=4o
We can solve this system using substitution. In this case, we can substitute 4o for c:
6(4o)+8o=64
24o+8o=64
Combine like terms
32o=64
Divide both sides by 32
o=2
Substitute 2 for o to solve for c:
c=4o=4(2)=8
There are 8 crabs and 2 octopi

Solve by elimination.
The goal is to cancel out one of the variables in order to easily solve for the other variable.
Do this by changing the equations so that the coefficients of either x or y add up to 0.
Notice the coefficients of y are 3 and 3, if we make one of them negative then they add up to 0. 3+ (-3) = 0
Multiply 2nd equation by -1.
6x +3y = 9
-2x -3y = -1
__________
4x +0y = 8
Solve for x
4x = 8
x = 8/4 = 2
Plug x=2 back into one of original equations to find y.
---> 2(2) + 3y = 1
---> 4 + 3y = 1
---> 3y = -3
---> y = -1
Therefore solution is (2,-1)
Answer:
8
Step-by-step explanation:
We can use triangle inequality, let AC = x:
x+4 > 5
x+5 > 4
9 > x
Simplifying:
x>1
x>-1
9>x
Thus: 9>x>1
So the Largest whole number is 8
