astraxan [27]

i.e.2x+3x=30

Then ,by solving this eqation we get the value of x=6

After that put the value of x in the number of boys

What is the slope of (2,12) (4,20)

Ugo [173]

This is the formula for slope between two points:

$\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$y_{2} =20\\y_{1} =12\\x_{2} =4\\x_{1}=2$

so...

$\frac{20-12}{4-2}$

$\frac{8}{2}$

The slope is 4

Hope this helped!
