If x=y and a<b, then
a. a + b = b + y
b. a + x < b + y
c. a + x > b + y
d. a + x = b
e. a + x = y
2. If a<b and c<d, Then
a. ac = bd
b. a = d
c. b = c
d. a + c > b + d
e. a + c < b + d
3. If k<m and x=y, then
a. k-x > m-y
b. k+x = m+y
c. k-x < m-y
d. k+y = m+x
e. kx = my
4. If a=b and x>y, then
a. a-x = b-y
b. a-x > b-y
c. a-x < b-y
d. a+x = b+y
e.a+y = b+x
5. If x<y, z= x/2, and a= y/2, then
a. z < a
b. a > z
c. a = z
d. 2a > y
e. 2x > 2z
How do you do these? I can understand so an explanation would help. Thanks! :)
