If B = {−13, −9, −7, −3}, choose the set A that will make the following statement false.
Svetach [21]

Answer: c.A is the set of rational numbers

Step-by-step explanation:

B ⊆ A means that every element of B is an element of A

B = { -13 , -9 , -7 , - 3 }

The element of B are negative integers , this mean that the element of A must also be integers therefore :

Option a is correct.

Option b is also correct

Rational numbers are numbers that can be express in the form a/b , examples are : 1/2 , 3/ 4 , 5/6 ...

clearly , this does not necessarily define A , so option c is the odd one out

29/12 + 23/6 + 11/3 - 5 / 12
Hoochie [10]

Answer:

57/6 or 9 1/2.

Step-by-step explanation:

The lowest common denominator is 12 so we convert the fractions to denominator 12:

29/12 + 23/6 + 11/3 - 5 / 12

= 29/12 + 46/12 + 44/12 - 5/12

= 114/12

= 57/6

or 9 1/2
