Answer:
There are 8 quarters in the jar.
Step-by-step explanation:
There are 20 coins in a jar.
Each coin is either a nickel or a quarter.
The probability of selecting a nickel is 0.6
Let's assume there are x number of nickels
The probability of selecting a nickel coin is = 0.6
So x = 0.6 × 20 = 12
Hence there are are 12 nickel coins and 20 - 12 = 8 quarter coins.

<h2>Step-by-step explanation:
- 2(5y - 1) - y = - 4(y - 3)
Expand the terms in the bracket
That's
-10y + 2 - y = - 4y + 12
Group like terms
Send the constants to the right side of the equation and those with variables to the left side
That's
- 10y - y + 4y = 12 - 2
- 7y = 10
Divide both sides by - 7
We have the final answer as
