A 4cm x 6cm rectangle sits inside a circle with radius of 11 cm whats the area of the shaded region

Dan has $7 and Julio has $12

Step-by-step explanation:

Julio = x

Dan = y

They both have a total of $19:

x + y = 19

Julio has 5 more dollars than Dan:

(Therefore Dan would need 5 more dollars to catch up to what Julio has)

y + 5 = x

We now plug in one equation into the other and get:

y + (y+5) = 19

2y+5 = 19

2y = 14

y = 7

Plug in Dan's amount into the initial equation and we get:

7+5 = x

x =12
