Question

Write and solve the equation, and then check your answer. The sum of two and two tenths and a number is five. 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

GIVEN :

The statement of the equation is "The sum of  the two and two-tenths and a number is five"

TO FIND :

The correct equation for the given statement.

SOLUTION :

Given statement of the equation is "The sum of the two and two-tenths and a number is five"

Let the number be n.

The given statement can be written as

$2\frac{2}{10}+n=5$

$\frac{22}{10}+n=5$

$2.2+n=5$

$n=5-2.2$

$n=2.8$

∴ the solution of the equation is n=2.8
