The product of a number minus ten and nine equals fifty when decreased by seven. which equation represents the sentence? a.7(x - 10) - 9 = 50 b.7(10 - x) - 9 = 50 c.9(x - 10) - 7 = 50 d.9(10 - x) - 7 = 50

Answer : C is the right answer.

Given statement: The product of a number minus ten and nine equals fifty when decreased by seven equals fifty when decreased by seven.

let the number be x then

The product of a number minus ten and nine =9(x-10),[which means option A and B are incorrect]

According to the statement

9(x-10)-7=50, which is the C option

Therefore C is the right option.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
