Question

Eric plays basketball and volleyball for a total of 95 minutes every day. He plays basketball for 25 minutes longer than he plays volleyball. Part A: Write a pair of linear equations to show the relationship between the number of minutes Eric plays basketball (x) and the number of minutes he plays volleyball (y) every day. (5 points) Part B: How much time does Eric spend playing volleyball every day? Show your work. (3 points) Part C: Is it possible for Eric to have spent 35 minutes playing basketball if he plays for a total of exactly 95 minutes and plays basketball for 25 minutes longer than he plays volleyball? Explain your reasoning. (2 points)

Answer 1

Answer:

A) x = y+25

B) 35 minutes

C) 35 ≠85

Step-by-step explanation:

A)  

As we know

X = number of minutes Eric plays basketball

Y = Number of minutes he plays volleyball  

x+y= 95

x = y+25  

B)  

We will replace  

x=y+25 in the first equation and we will get (y+25) + y =95  

On solving,  

y+25+y =95  

25+2y=95  

2y=95-25  

2y=70  

y = 70/2  

y = 35 minutes  

C) X = 35  

x+y= 95  

35+y =95  

y= 95-35  

y = 60 minutes  

Substituting value of Y as 60 , we get  

x = y+25

35 = 60+25

35 ≠85
