The amount of time it takes to finish a race might be a function of which of the following?A.) the entry fee for the race
B. ) the number of people involved in the race
C.)the distance of the race

Answers

The correct answer is:

C) The distance of the race.

Explanation:

If one variable is written as a function of another, this means there is a relationship between the two variables.

There will be a relationship between the time it takes to finish a race and the distance of the race. The longer the distance of a race is, the more time it will take to finish it. Therefore the time can be written as a function of the distance.

The correct answer is C. The distance of the race

The entry fee and the number of people involved can have no influence on the amount of time it takes to finish it.

18 (m + 4/9) - 16 = 118

Answers

18 (m + 4/9) - 16 = 118 Get rid of the parentheses by multiplying 18 * M + 4/9

18M + 8 - 16 = 118 Subtract 8 - 16

18M - 8 = 118 Add 8 to both sides

18M = 118 + 8 Add 118 + 8

18M = 126 Divide 126/18

M = 7

18(m+4/9)-16=118
18m+18*(4/9) -16 = 118 (i used distributive property)
18m+8 -16 = 118
18m-8 = 118
18m = 126 ( i added 8 to both sides)
m = 126/18
m = 7
