The sum of two numbers is 36. their difference is 8. find each of the numbers. what is their product?

X + y = 36
x - y = 8
Add the equations
2x = 44
x = 22
y = 14

the product is 22*14 = 308

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
