Cash register contains only five dollar and ten dollar bills. Contains twice as many five's as ten's The total amount of money in the cash register is $720. How many tens are in the cash register? 

36

Step-by-step explanation:

5x + 10y = 720

y=1/2x

tens = 36

the answers c

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
