Answer 1

Answer:

D. 15

F. - 133

Step-by-step explanation:

Given values of the variables are as follows,

x = 4

a = - 4

b = - 5

For Question D,

16 - 7b + 4a - 5x

= 16 - 7 ( - 5 ) + 4 ( - 4 ) - 5 ( 4 )

= 16 + 35 - 16 - 20

= 35 - 20 = 15

For Question F,

5b + 7a - 20x

= 5 ( - 5 ) + 7 ( - 4 ) - 20 ( 4 )

= - 25 - 28 - 80

= - 133
