The ratio of Sam's to John's money is 4.7. The difference in their money is $9. How much money does Sam have?

the answer is 3.4.7 because it's the answer

Sam has 21 dollars

the ratio is 12:21

Step-by-step explanation:

Original Ratio = 4:7  

Difference of numbers = 9

Take the first number = 4x

Then the other = 7x

gives us: 7x-4x=9

Now we find a factor of 9: 3x=9

x=9/3

x = 3

Therefore the 1st number = 4x = 4(3)= 12

2nd number = 7x = 7(3)=21

Proof: 21-12=9

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
