So the answer is 14 ounces
Explanation
Since 16.8 is the original plus 20% we could say 16.8=120%
And since X is the original we could say X=100
So using that info we could put it into a proportion
120/100=16.8/x or
120. 16.8
——=. ———-
100. X
Then we cross multiply and divide
So,
120x=16.8(100)
120x=1680 then divide both sides by 120
X=14
Well you may already know that 8 x 5 = 40.
So, add zeros.
80 x 50 = 4,000.
So now, make it division.
4,000/80 = 50.
A(-1;14), x=-1, y=14
B(2;-10), x=2, y=-10
General equation for linear function is 
Let's solve system of equations

Answer:
50% or 1/2
Step-by-step explanation:
Chance is like probability, so the chance of rolling a even number out of 1, 2, 3, 4, 5, and 6 is half of them, they are 2, 4, and 6. In fraction form it is 1/2, and in percent form it is %0%. Hope this helps.
40/60= 0.67 (i.e. 2/3)= about 66.67%
