one positive number is 5 times another number. the difference between the two numbers is 764, find the numbers
damaskus [11]
<h3><u>The first number, x, is equal to 955.</u></h3><h3><u>The second number, y, is equal to 191.</u></h3>

x = 5y

x - y = 764

Because we have a value for x, we can plug it into the second equation to solve for y.

5y - y = 764

Combine like terms.

4y = 764

Divide both sides by 4.

y = 191

Because we have a value for y, we can solve for x.

x = 5(191)

x = 955

Round to the nearest tenth. The 9 in the hundredth place tell us to round the 2 to a 3 in the tenth place.
