Question

Which phrase is not a way to state the meaning of the expression y-7

Answer 1

Answer:

B. A number subtracted from 7 .

Step-by-step explanation:

The given choices are

A. 7 less than a number

B. A number subtracted from 7

C. A number minus 7

D. The difference between a number and 7

The given expression is: $y-7$

Remeber, variabels are called "a number" indicating its variability, because they are unknown values.

So, this expression can be written as: "7 less than a numer" or "the difference between a number and 7" or "a number minus seven".

Therefore, among the options, choice B doesn't represents the given expression, because "a number subtracted from 7" is equivalent to $7-y$ which is not the case here.

So, the right answer is B.
