A^2-3a+14 is the answer :)
Just simply divide then multiply by 100
1/6= 0.166667×100=<span>16.6667%
So </span>16.6667% is the answer
if you want it rounded 16.7%
Answer:
17500
Step-by-step explanation:
you just multiply it by 35 if it is pennies but you have to tell me if it is dimes or whatever
The lines are parallel, because they have the same gradient but are just in different positions ie. y = x-9.
Let n be a number of balls: n = 14
In one pan you have 8 balls: 8n
In the other pan you have the rest of balls (14 - 8 = 6) along with a <span>weight of 20 grams = 6n + 20
So the pans are balanced:
8n = 6n + 20
Now, just solve the equation:
8n - 6n = 20
2n = 20
n = 20/2
n = 10
So, you know that a ball weights 10 grams.</span>
