The correct equation is n - 31 = 52

To check the solution, substitute 83 for the variable in the equation

This is an addition problem.

To solve the equation, add 31 to both sides.

Step-by-step explanation:

A number decreased by thirty-one is fifty-two

That means:

  • Subtract 31 from a number
  • The difference equal 52

Assume that the number is n

∵ The number is n

∵ When n decreased by 31 the answer is 52

∴ The equation is n - 31 = 52

The correct equation is n - 31 = 52

∵ n - 31 = 52

- To find n add 31 to both sides of the equation

∴ n - 31 + 31 = 52 + 31 ⇒ addition property

∴ n = 83

-To check the equation substitute n by 83 in the left hand side, the

  answer must be equal the right hand side

∵ Left hand side = 83 - 31 = 52

∵ Right hand side = 52

∴ n = 83 is correct answer

To check the solution, substitute 83 for the variable in the equation

This is an addition problem.

To solve the equation, add 31 to both sides.

Answer:

The correct equation is n minus 31 = 52.

To check the solution, substitute 83 for the variable in the equation.

This is a subtraction problem.

To solve the equation, add 31 to both sides.

Step-by-step explanation:

I took the exam. these are right

These are WRONG

The correct equation is n + 31 = 52.

To check the solution, substitute 21 for the variable in the equation.

This is an addition problem.

To solve the equation, subtract 31 from both sides.

Giovanna has a score of -5 in canasta Vera score is -10
MariettaO [177]

Answer:

5

Step-by-step explanation:

I do not fully understand what the question is because you didn't ask a question, so I just found the difference between the 2 scores, which would be a positive 5.

Or if its asking which score is greater it would be Giovanna because her score was closer to zero than Vera's score.
