The problem said that for each part, there is 1/10 mile long. If Marsha finished 5 parts of the race, just multiply 5 by 1/10 and you will get 5/10 or ½ or 0.5 miles. Therefore, Marsha finished 0.5 miles of the race.

Answer:

Final answers are ,

• 9

•-7

• 7

• -85

Step-by-step explanation:

Given that when we input a number then first it will be multiplied by 2 and finally decreased by(-1) .

Input 5 :-

• Firstly Multiplying it by 2 → 2× 5 = 10

• Subtracting 1 from it → 10 - 1 = 9

Output = 9

====================================

Input (-3) :-

• Firstly Multiplying it by 2 → 2× -3 = -6

• Subtracting 1 from it → -6- 1 = (-7)

Output = (-7)

====================================

Input 4 :-

• Firstly Multiplying it by 2 → 2× 4 = 8

• Subtracting 1 from it → 8 - 1 = 7

Output = 7

====================================

Input (-42) :-

• Firstly Multiplying it by 2 → 2× -42 = -84

• Subtracting 1 from it → -84 - 1 = -85

Output = (-85)
