Which of the following illustrates the truth value of the given statements? 5 • 3 = 15 or 7 + 5 = 20 f t → t t t → t f f → f t f → t

D. T F → T

Step-by-step explanation:

We are given the statements,

5 × 3 = 15 or 7 + 5 = 20.

Now, we will check whether the statements are true or false.

So, we have,

Statement ' 5 × 3 = 15' is true i.e. T

Statement ' 7 + 5 = 20' is false i.e. F

Hence, the correct truth value of the given statements is T F → T.

So, option D is correct.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
