The two expression below are equivalent y(2.5+7)+y-2 10.5y-2 which statement best explains why the expressions are equivalent a the expressions have the same value for any value of y b the expressions have the same value for only whole number values of y c the expressions have the same value only when y is an odd number. d the expressions have the same value only when y is an even number.

The two expressions given are:

and

The first expression can be simplified to be:

As we can see, simplifying the first expression gives us the second expression and thus we can see that both the expressions are equal and they will remain equal for any value of y.

Thus, out of the given options, Option A is the correct one. That is, "the expressions have the same value for any value of y".

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.
