Amajor league baseball player chews 17 pieces of gum per game. write an algebraic expression to show how many pieces of gum he might chew in n games.

17n

Step-by-step explanation:

Given : A major league baseball player chews 17 pieces of gum per game.

No. of pieces of gum he chew in one game =17

Let n denotes the number of games played by him.

Then, the total number of pieces of gum he might chew in n games will be :

=No. of pieces of gum he chew in one game x n

= 17 x n = 17n

Hence, the algebraic expression to show how many pieces of gum he might chew in n games = 17n

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
