the product of a number and five decreased by eight
5n - 8
To find the product of a number and five decreased by eight, follow these steps:
1. Let's represent the number as 'x'.
2. Multiply the number by five: 5x.
3. Decrease the product by eight: 5x - 8.
Therefore, the expression for the product of a number and five decreased by eight is 5x - 8.
To find the product of a number and five decreased by eight, we follow these steps:
1. Let's assume the unknown number as "x".
2. Multiply the number by five, which gives us "5x".
3. Subtract eight from the product obtained in step 2, which gives us "5x - 8".
4. The final expression "5x - 8" represents the product of a number and five decreased by eight.
For example, if we substitute the value of "x" as 3 into the expression "5x - 8":
5(3) - 8 = 15 - 8 = 7
So, the product of 3 and five decreased by eight is 7.
