The temperature at sunrise was -3*F. By noon, the temperature climbed 18 degrees. By sundown the temperature was -14*F. How much
Natalija [7]

Answer:

32*F

Step-by-step explanation:

* = degrees

Started at -3*F

By noon, the temperature climbed 18* = +18*

By sundown the temperature was -14*F

What we want to know: How much did the temperature drop between noon and sundown?

This is actually really easy!

What was the temperature at noon?        --> 18*F

What was the temperature at sundown? --> -14*F

So what is the difference between 18* and -14*? We can't use an equation, so we will solve manually.

The distance from -14 to 0 is 14 degrees. Keep that in mind.

The distance from 18 to 0 is 18 degrees. Keep that in mind.

So what is 14 + 18? 14 + 18 = 32*.

So, the temperature dropped 32*F between noon and sundown.

I hope this helps! I know this was a little messy, but that is because we couldn't use an equation/expression to solve this.

Find the midpoint of the segment below
aniked [119]
1.
If we are given 2 points A(a, b) and B(c, d), 

the midpoint M, of segment AB has coordinates:

M_A_B=( \frac{a+c}{2} ,  \frac{b+d}{2} )

2.
We are given the points A(2, 3) and B(10, 3)

the midpoint of AB, is given by the above formula:

M_A_B=( \frac{2+10}{2} , \frac{3+3}{3} )=(6, 3)

3. 
Remark, since the segment is horizontal, that is the y-coordinate of both points is 3, the y coordinate of the midpoint will also be 3.

While the x coordinate is still found by \frac{2+10}{2}

Answer: (6, 3)
