X intercept: when y is zero
y intercept: when z is zero
So...

3/5(0) + 1/2y=30
1/2y=30
multiply by 2 (both sides)
y=60

3/5x + 1/2(0)=30
3/5x=30
multiply by 5/3 (both sides)
x=18

x-intercept: (18,0)
y intercept: (0,60)

Substitute X or Y With 0 So It Would Be 3/5(0) +1/2y = 30
1/2y=30
Divide Get Y And Do The Same For X

Answer:

Step-by-step explanation:

Total number of students who roller skated = 80

Number of students who roller skated with laser tag = 39

Number of students who roller skated with no laser tag = 80 - 39 = 41

Therefore, percentage of students who roller skated with no laser tag = \frac{41}{154}\times 100 = 27%

Since, number of students who played laser tag = 85

Percentage of students who played laser tag = \frac{85}{154}\times 100 = 55%

Total number of students who played no laser tag = 45% of 154 = 69

Number of students with no roller skates and no laser tag = 69 - 41 = 28

Percentage of students with no roller skates and no laser tag = \frac{28}{154}\times 100        

                                                                                                       = 18%

Percentage of students who played with no rollers skates = (30 + 18)%

                                                                                                 = 48%

                                  Laser tag                 No laser tag                Total

Roller skate                     25%                           27%                      52%

No Roller skate               30%                           18%                      48%

Total                                55%                           45%                      100%
