Answer:
A and B are true
Work:
A)
100 = 2y + 2
100 - 2 = 98
98 = 2y
98/2 = 49
Y = 49
105 = 5x
105/5 = 21
X = 21
49 + 21 = 70
This statement is true!
B)
Y = 49
The square root of 49 is 7, meaning the square root of y is also 7
X = 21
21/3 = 7
7 = 7
This statement is true!
C)
Y = 49
49 is not greater than 50
This statement is false!
D)
Y = 49
X = 21
21 x 3 = 63
63 is not equal to and is greater than 49
This statement is false!
