Answer:

20

Step-by-step explanation:

Our expression:

2 * (18 + - 8)

Plus then minus (+ -) is the same as just minus ( - )

Some examples:

1 + (+ 1) = 2

1 + (- 1) = 0

1 - (+ 1) = 0

1 - (- 1) = 2

Thus, 18 + - 8 is the same as 18 - 8

2 * (18 + - 8) =

= 2 * (18 - 8) =

= 2* (10) =

= 2 * 10 =

= 20

Answer: 20

Anastasy [175]
Kim drives = x 
Terry drives = 2x 
Jerry drives = 6x 

Let us go through our answer choices and choose one.

B is incorrect because it equals what all of the drivers drive. 

2(x+3)
2*x + 2*3
2x + 6x

C is incorrect because we are not being asked to subtract.

D is correct because Jerry drives 3 times as much as terry.

2x*3
6x
