Option A is correct.
Step-by-step explanation:
We need to identify which statement is true in matrix addition.
In matrix addition we just add the corresponding elements.
In the options given only Option A is correct i.e, (n+4)-7 = 18
All other options have error in them.
In Option B there should be -12 instead of +12
In Option C there should be -11 instead of 11
In Option D we are not adding corresponding entries.
So, Option A is correct.

Answer:
The CONVERSE of p → q is q → p will be written as
i.e If 3x -4 = 20, then 2x = 16.
Step-by-step explanation:
Given:
p: 2x = 16
(one statement)
q: 3x – 4 = 20
(another statement)
The given statement is p → q can be written as
i.e IF 2x = 16, then 3x – 4 = 20
The CONVERSE of p → q is q → p will be written as
i.e If 3x -4 = 20, then 2x = 16.
Answer:
The answer is 0.25
Step-by-step explanation:
(1)we group like terms by subtracting 32.50 by 28.75
(2) we subtract 20 and 5 to give us a value of 15
(3)when we subtract 32.50 and 28.75 we get a value of 3.75
(4)so the equation will look like this 3.75t = 15
(5)we divide 3.75 we both the two equations
(6)With a correct calculation, Your answer should be t = 0.25
X+y=3
Subtract x from both sides
y=-x+3
Substitute
2x--x+3=6
2x+x+3=6
3x+3=6
Subtract 3 from both sides
3x=3
Divide both sides by 3
x=1
