Answer:
8 and - 2
Step-by-step explanation:
let x be the larger number and y the smaller , then
x = 5y + 18 → (1)
3x + 4y = 16 → (2)
substitute x = 5y + 18 into (2)
3(5y + 18) + 4y = 16 ← distribute parenthesis and simplify left side
15y + 54 + 4y = 16
19y + 54 = 16 ( subtract 54 from both sides )
19y = - 38 ( divide both sides by - 19 )
y = - 2
substitute y = - 2 into (1)
x = 5(- 2) + 18 = - 10 + 18 = 8
then larger number is 8 and smaller is - 2
The speed of the current that Micah rows his boat on would be 3 miles per hour assuming that he is rowing 4.48 miles downstream with the current, in 0.32 hours.
The answer is 150.
(5)^2(9-3)
25(6)

8*(1/x) = 4*(1/8)
8/x = 4/8
64 = 4x
x = 16
