Suppose you have 5 quarters and 5 pennies in your wallet. You select two coins from your wallet without looking. If the first coin is not replaced, what is the probability of selecting a quarter both times?

4/5

Step-by-step explanation:

If you have 5 quarters and 5 pennies the fraction would be... 5/5. If you take away two coins you would most likely take 1 penny and 1 quarter, which leaves 4 quarters. Therefore the answer is 4/5.

Hope this helps :)

50% it can be like you can pick 2 pennies you don't know that is why you have to look

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
