Chin correctly translated the following phrase into an algebraic expression.
“one-fifth less than the product of seven and a number”
Which expression represents Chin’s phrase?
7 n + one-fifth
StartFraction 7 n minus 1 Over 5 EndFraction
StartFraction 7 n + 1 Over 5 EndFraction
7 n minus one-fifth
7n - 1/5
unless "1/5 less" means 4/5 as much., as in a 20% sale means the price is 1/5 less than it was.
The words are ambiguous.. Use math to be clear.
4/5 * 7 n = 28 n/5 = (25 + 3) n/5= 5 n + 3 n/5
That does not seem to be a choice.
To translate the phrase "one-fifth less than the product of seven and a number" into an algebraic expression, we can break it down into three parts:
1. The product of seven and a number: This is represented by the expression 7n, where n represents the unknown number.
2. One-fifth less than the product: This means that we subtract one-fifth (1/5) from the product. Hence, we subtract 1/5 from 7n.
So, combining these two parts, the algebraic expression that represents the phrase is:
7n - 1/5
Therefore, the correct expression is: 7n minus one-fifth.
