he correct statement is:
"The temperature started at 78 degrees and decreased by 6 degrees, then decreased by 5 degrees."
<h3> Which statement best describes this expression?</h3>
Here we have the expression:
78+(-6)-5
So we start at 78, then we subtract 6, and then we subtract 5.
This means that the initial temperature is 78, then it decreases by 6 degrees, and then it decreases again by 5 degrees.
Then the correct statement is:
"The temperature started at 78 degrees and decreased by 6 degrees, then decreased by 5 degrees."
Which is the third statement counting from the top.

When you are going from a larger measurement (such as meter) to a smaller measurement (such as centimeter), you will have to multiply by units of ten. Specifically if you are going from m to cm, you will use (n x 10^2) with n being the given number for meters. When you are going from a smaller measurement (such as centimeter) to a larger measurement (such as meter), you will have to divide by units of ten. Specifically if you are going from cm to m, you will use (n / 10^2) with n being the given number for centimeters.

Distance = Speed * Time
She runs 5 miles in 45 mins. Her speed is Distance/Time
Speed = Distance/time
= 5 miles/45mins
= 0.11miles/min
Now how far can she run in 120 mins?
Distance = Speed * Time
=0.11miles/min * 120mins
= 13.33miles.
Hope this helps :)
