One positive integer is 5 times another positive integer and their product is 320. What are the positive integers?

1 answer:

7 0

Answer by CubeyThePenguin(3113) (Show Source): You can put this solution on YOUR website!
x = 5y
xy = 320

Substitute the first equation into the second equation
(5y)(y) = 320
5y^2 = 320
y^2 = 64
y = 8 (y must be positive)

The integers are (x, y) = (40, 8).

Answer:

The answer is -(4/5)y - 3.

Step-by-step explanation:

The steps are :

$\frac{1}{5} y - \frac{3}{5} y + 5 - \frac{2}{5} y - 8$

$= ( \frac{1 - 3 - 2}{5} y) + (5 - 8)$

$= - \frac{4}{5} y - 3$

7932 x 56 = 444192 and since it’s asking you to multiply by .56 and 793.2, just move the decimal over to the left three places in your answer since there’s three digits after the decimals in your factors. so you get 444.192
