Write a system of equations and solve using elimination. ricardo has two bills. the two bills together are $21. one bill is worth $19 more than the other. what are the two bills?

The worth of one bill is $20 and the worth of the other bill is $1

Step-by-step explanation:

Let

x> the worth of one bill

y ---> the worth of the other bill

I assume x > y

we know that

x+y=21 > equation A

x=y+19 ---> equation B

Solve the system by elimination

Multiply equation B by -1 both sides

-x=-y-19 > equation C

Adds equation A and equation C

x+y=21

-x=-y-19

y=21-y-19

2y=2

y=1

Find the value of x

x=y+19 > x=1+19=20

therefore

The worth of one bill is $20 and the worth of the other bill is $1

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
