Answer:
104
Step-by-step explanation:
Any expression multiplied by 0 equals 0
when adding or subtracting 0, the quantity doesn't change
All of the answer choices except B would be correct for this problem.
Answer:
None of the above.
Step-by-step explanation:
The system of equations which should have the same solution as the system below;
x + 4y = 11
4x + 2y = 16
is
x + 4y = 11
-8x - 4y = - 32
This system of equations is missing from your choices.
The trick is that -2 is multiplied to the second equation of the first system.
i.e -2 (4x + 2y = 16) gives; -8x - 4y = -32
Answer:
Question 12 - 
Question 13 - 
Step-by-step explanation:
The simplified version of this would be: (4x+16y)+(12x+3y). You then combine like terms (4x+12x=16x) and (16y+3y=19y). Since this is the most simplified you can make the equation THE ANSWER would be 16x+19y
