Given the following definitions: U = {1, 2, 3, 4, 5, 6, 7} A = {1, 2, 4, 5} B = {1, 3, 5, 7} How many elements are in B' ?

Elements are 2,4,6. There are 3 elements in B complement

Step-by-step explanation:

B complement means elements that are not present in B and they are 2,4,6.So there are 3

elements

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
