X=number of boys
y=number of girls
(x+y)=number total of students
We can suggest the following system or equations:
x/y=4/5
y=95
Therefore:
x/95=4/5
x=(4*95)/5=76

(x+y)=76+95=171

Answer: there are 171 students in this school.

Goodmorning all help me guys​

Answer:

Step-by-step explanation:

1) Distance covered by motorcycle = x

y  = 50 + (x -2)*10

2)Distance traveled = 5 km

y = 50 + ( 5-2) *10

  = 50 + 3*10

  = 50 + 30

  = 80

Seth will be paid Php 80

3)  y = 120

50 + (x - 2)* 10 = y

50 + (x -2) *10 = 120

50 + 10x - 2*10 = 120

50 + 10x - 20  = 120

30 + 10x = 120

       10x = 120 - 30

       10x = 90

           x = 90/10

x = 9

A passenger can travel 9 km.

4)y = (x - 2)*10

 y = 10x - 20

20 + y = 10x

     20 = 10x - y

10x - y = 20      {Ax + By = C form}
