Question

HURRY UP PLZ Which statements are correct? Check all that apply. The word “sum” means the result of adding two numbers. The correct equation is n – 2.2 = 5. The correct equation is n + 2.2 = 5. The solution of the equation is n = 7.2. The solution of the equation is n = 2.8. Check the solution by substituting the value for n and simplifying.

Answer 1

The correct equation is: n + 2.2 = 5

The solution is: n = 2.8

Explanation:

Sum is addition,

so the correct equation is:

n + 2.2 = 5

The solution is:

n = 2.8

Verification:

2.8 + 2.2 = 5

5 = 5 (true)

Answer 2

The thing to look at here is when it states "The word “sum” means the result of adding two numbers."

We can eliminate [ The correct equation is n – 2.2 = 5 ] since its subtracting not adding.

Since, we know that right equation is [ n + 2.2 = 5 ], we can solve for n.

n + 2.2 - 2.2 = 5 - 2.2

n = 2.8

Therefore, the correct answers are answer:

The correct equation is n + 2.2 = 5.

The solution of the equation is n = 2.8.

Best of Luck!
