Answer:
D. 9n = 27
Step-by-step explanation:
If we need one adult for every 9 students, we can represent that as 9n:
if n is the number of adults.
Because we have 27 students, the equation 9n = 27 works.
A better way of formatting the equation is:
n = 27/9
Because it directly shows what the number of adults is, but with some reformatting, it is clearly the same equation.
The statement which identifies Melissa’s error and the correct answer is; Melissa added incorrectly. The correct answer is 4.5°F
<h3>Temperature</h3>
- Initial temperature = -20.5°F
- Change in temperature per hour = 5°F
- Number of hours = 5
New temperature = Initial temperature + (Change in temperature per × Number of hours)
= -20.5°F + (5°F × 5)
= -20.5°F + (25°F)
= 4.5°F

Answer:
Step-by-step explanation:
We will try both by doing addition :
1341+625+0=1966
and
1/2*1341+625=2591/2=1295.5
As 1966 is greater then 1295.5 so 1341+625+0 is greater then 1/2*1341+625
