Answer:
option A) Agree, because the solutions are the same is correct.
Step-by-step explanation:
FIRST SYSTEM


solving the system



adding the equation




so the system becomes

solve -5y for y

Divide both sides by -5

simplify



subtract 16/5 from both sides


Divide both sides by 6


Therefore, the solution to the FIRST SYSTEM is:

SECOND SYSTEM


solving the system







so the system of equations becomes

solve -5y for y

Divide both sides by -5

Simplify




Divide both sides by 2

Simplify

Therefore, the solution to the SECOND SYSTEM is:

Conclusion:
As both systems of equations have the same solution.
Therefore, we conclude that Albert is right when says that the two systems of equations shown have the same solutions.
Hence, option A) Agree, because the solutions are the same is correct.

Answer: 11.4
Simply multiply 38 by .30 to find the percentage of the number.
Answer:
Part A
30
44
26
Part B
176
Step-by-step explanation:
Total: 65+110+75 = 250
P(O) = 75/250 × 100 = 30%
P(A) = 110/250 × 100 = 44%
P(K) = 65/250 × 100 = 26%
Apple juice:
44% of 400
44/100 × 400
