Sure, I can check your answers for you! Let's go through each question.

1) Find an equivalent expression without parentheses:
Your answer: -y-87
To check this, distribute the negative sign to both y and 87: -1 * y + -1 * 87 = -y - 87. So your answer is correct: -y - 87 is an equivalent expression without parentheses.

3) Solve -3x-13x=96:
Your answer: x = -6
To solve this equation, combine like terms: -3x - 13x = 96
Simplifying further: -16x = 96
Divide both sides of the equation by -16: x = 96 / -16 = -6.
So your answer is correct: x = -6.

4) Find the decimal notation for 14/25:
Your answer: .56
To convert a fraction to a decimal, divide the numerator (top number) by the denominator (bottom number). In this case, 14 divided by 25 gives you 0.56. So your answer is correct: the decimal notation for 14/25 is 0.56.

5) Divide if possible: 7/0:
Your answer: 0
Division by zero is undefined in mathematics. It is not possible to divide any number by zero. So your answer is incorrect. The correct answer is that dividing 7 by 0 is not possible.

6) Solve 7x + 10 = 52:
Your answer: x = 6
To solve this equation, isolate the variable x by subtracting 10 from both sides: 7x + 10 - 10 = 52 - 10. Simplifying, 7x = 42. Now divide both sides of the equation by 7 to find x: x = 42 / 7 = 6. So your answer is correct: x = 6.

Overall, you had four correct answers and one incorrect answer. Keep practicing and asking questions if you need further clarification!
