B is the answer.............
Answer:
i think its 3/8 because if 5/8 are male the rest are female so you de 8/8 - 5/8 and you will get 3/8 but i dunno why it says about the aquariaum when the question is about how many female staff therer are
Answer:
i think b
Step-by-step explanation:
9=3^2 and 10^4=(10^2)2
Answer: B and E apply. I know for sure.
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)
