The required temperature at 5:00 am is -12° F.
Given,
The temperature at 5:00 p.m. was -4° F. By 5:00 a.m. the temperature had decreased by 8° F what was the temperature at 5:00 a.m is to be determined and shown it with a vertical number line.
<h3>What is a number line?</h3>
A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
The temperature at 5:00 p.m. was -4° F.
By 5:00 a.m. the temperature had decreased by 8° F.
The temperature at 5:00 a.m. = - 4 - 8
= -12° F
Thus, the required temperature at 5:00 am is -12° F.

Solution:
we are given that
Each cow has 4 legs and each chicken has 2 legs.
A boy counts 42 heads and 144 feet.
we have been asked to find how many cows are there?
Let there are x cows and y chicken.
Then we can write
![x+y=42....(i)\\\\\text{Sum of Heads}\\\\4x+2y=144\\\\\text{Sum of feet }\\\\\Rightarrow 2x+y=72....(ii)\\\\\text{Now solve these two equation together we get}\\\\2x+(42-x)=72\\\\2x+42-x=72\\\\x=72-42=30\\](https://tex.z-dn.net/?f=%20x%2By%3D42....%28i%29%5C%5C%5C%5C%5Ctext%7BSum%20of%20Heads%7D%5C%5C%5C%5C4x%2B2y%3D144%5C%5C%5C%5C%5Ctext%7BSum%20%20of%20feet%20%7D%5C%5C%5C%5C%5CRightarrow%202x%2By%3D72....%28ii%29%5C%5C%5C%5C%5Ctext%7BNow%20solve%20these%20two%20equation%20together%20we%20get%7D%5C%5C%5C%5C2x%2B%2842-x%29%3D72%5C%5C%5C%5C2x%2B42-x%3D72%5C%5C%5C%5Cx%3D72-42%3D30%5C%5C%20)
Hence Number of cows=30
4th root of x^5
x^5 = x(x^4)
= x times 4th root x
last solution
the 5th root to the 5th power cancels out leaving -243
