​

Answer 1

Answer:

c) y decreased by 3 is equal to 7.

Step-by-step explanation:

a) 3 decreased by y is 7 can be expressed as (3 - y) = 7 =>y = 3-7 = -4

b) 3 minus y is 7 can be expressed as (3 - y) = 7 =>y = 3-7 = -4

c)y decreased by 3 is equal to 7 can be expressed as (y - 3) = 7 =>y = 7 + 3 = 10.

Clearly, above results are not same.  ∴ (d) cannot be true.

Therefore, the correct option is c) y decreased by 3 is equal to 7.
