Answer:

Total students  = 1240

Step-by-step explanation:

Boys : girls = 11 : 9

Number of boys  = 11x

Number of girls  = 9x

11x - 9x = 124

       2x = 124

         x = 124/2

        x = 62

Number of boys  = 11x = 11 *62 = 682

Number of girls  = 9x   = 9*62    = 558

Total students  = 682 + 558 = 1240

sin45h/sin45=12/sin 45

h=16.9

after finding the hypotenuse you can then use it to find x by using tan

tan60=16.9/x

tan60x/tan60=16.9/tan60

6x+2y=<br> 6x+2y=<br> \,\,16<br> 16<br> 2x-2y=<br> 2x−2y=<br> \,\,32<br> 32
Ivanshal [37]

Answer:

x = 6, y = -8

Step-by-step explanation:

First we take the equations side by side and put them like this:

 6x + 2y = 16

+ 2x - 2y = 32

8x = 48

Then solve for x.

x = 6

Then insert x back into either equation

2(5) - 2y = 32

10 - 2y = 32

solve for y,

y = -10
