4:1/6 if you add all the instruments you get 120 then you divide it by six and you get 20 snare drums
X=-4 cause
-2=x+2
Then -4=x
Take y=3 and plug it into y=-3x+6. This gives you 3=-3x+6. Solve for x, you get x=1. Now plug 1 into y=-3x+6 and you get 3. Answer is (1,3)
You can solve this by cross multiplying. 20 ounces/$7=x ounces/$17. multiple $17 by 20 ounces and $7 by x ounces. (17x20=7x). 17x20=340, so 340=7x. Divide both sides by 7, and you will get x equals about 48.6.
