Question
Mary is 65.3 inches tall and her sister Tonya is 68 inches tall. Tonya wants to know how many inches taller she is than mary. Which equation and solution can be used to solve this problem?
Correct equation: _ ( x + 68 = 65.3, 65.3 - x = 68, x - 65.3 = 68 , 65.3 + x = 68 )
How to solve: _
( subtract 65 from both sides of the equation, add 68 to both sides of the equation, subtract 65.3 from both sides of the equation, add 65.3 to both sides of the equation.)
Correct answer: _ (2.7 inches, 133.3 inches)
Correct equation: _ ( x + 68 = 65.3, 65.3 - x = 68, x - 65.3 = 68 , 65.3 + x = 68 )
How to solve: _
( subtract 65 from both sides of the equation, add 68 to both sides of the equation, subtract 65.3 from both sides of the equation, add 65.3 to both sides of the equation.)
Correct answer: _ (2.7 inches, 133.3 inches)

To find out how many inches taller Tonya is than Mary, we can use the equation that represents the difference in their heights. Tonya's height (68 inches) minus Mary's height (65.3 inches) gives us the difference.
The correct equation is:
**68 - 65.3 = x** (where x represents the difference in height).
To solve:
**Subtract 65.3 from 68**:
- 68 - 65.3 = 2.7
The correct answer is:
**2.7 inches**.
So let's summarize:
Correct equation: **68 - 65.3 = x**
How to solve: **subtract 65.3 from both sides of the equation**
Correct answer: **2.7 inches**.
