7 – y?
28
D
y2 – 7

Part A) x + y=125, y = x +45

Part B) 85 minutes

Part C) Not possible

Step-by-step explanation:

Given that Angela plays soccer and golf for a total of 125 minutes everyday.

Number of minutes she plays golf = x minutes

Number of minutes she plays soccer = y minutes

Part A:

Total time she plays golf and soccer is 125 minutes.

Angela plays Soccer for 45 minutes longer than she plays golf i.e.

The pair of linear equations are:

Part B:

Let us solve the linear equations (1) and (2):

Putting value of y from equation (2) into equation (1):

Putting value of x in equation (2):

Angela plays golf for 85 minutes daily.

Part C:

Given that

Angela spends 80 minutes on soccer.

Total Time = 125 minutes

Time spent on golf = 125 - 80 = 45 minutes

Time spent on soccer longer than golf = 80 - 45 = 35 minutes 45 minutes

Hence, it is not possible for Angela to have spent 80 minutes playing soccer if she plays for a total of exactly 125 minutes and plays soccer for 45 minutes longer than she plays golf.

So, the answers are:

Part A) x + y=125, y = x +45

Part B) 85 minutes

Part C) Not possible
