Hey there! :)
There are 3 pennies
There is a total of 18 coins; 3 + 5 + 4 + 6 = 18
3 ÷ 18 = 0.16666666667 = 0.17
Your answer is 1/6 or 0.17
Hope this helps :)

Answer:
y = -5x+11
Step-by-step explanation:
To factor quadratic equations of the form ax^2+bx+c=y, you must find two values, j and k, which satisfy two conditions.
jk=ac and j+k=b
The you replace the single linear term bx with jx and kx. Finally then you factor the first pair of terms and the second pair of terms. In this problem...
2k^2-5k-18=0
2k^2+4k-9k-18=0
2k(k+2)-9(k+2)=0
(2k-9)(k+2)=0
so k=-2 and 9/2
k=(-2, 4.5)
