the bill 37.20
37.20 / 5
$7.44 each kid
7.44 - 5.25 = 2.19
$2.19 less if he paid separately

Answer:
false
Step-by-step explanation:
The conjecture shown in this problem statement does not follow from the examples offered. They support the notion that ...
1/x ≤ x . . . . for x ≥ 0 (<u>not x ≤ 0</u>)
There are several possible counterexamples showing the conjecture is FALSE.
- 1/0 is undefined
- 1/(-5) > -5 . . . . . . . . a case for x < 0
If the intended domain is x ≥ 0, then the conjecture can also be demonstrated to be false for 0 < x < 1:
- 1/(1/5) > 1/5
Well you have to go by 24x3 and that equals 72 miles
Rachel says that when she ran 115 yards she went farther than Beth who only ran 227 ft. Rachel is correct
<u>Solution:</u>
Given that , Rachel says that when she ran 115 yards she went farther than Beth who only ran 227 ft.
We have to remember that when 1 yard equals 3 ft.
Yes, what Rachel said is correct, let us see how it became correct
In normal view, 115 < 227 but here units are different.
Remember that, for any comparison between two things, we have to take the things in same units.
<em><u>Let us convert 115 yards to feet:</u></em>
![\begin{array}{l}{115 \text { yards }=115 \times 1 \text { yard }} \\\\ {115 \text { yards }=115 \times 3 \text { feet }=345 \text { feet }}\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bl%7D%7B115%20%5Ctext%20%7B%20yards%20%7D%3D115%20%5Ctimes%201%20%5Ctext%20%7B%20yard%20%7D%7D%20%5C%5C%5C%5C%20%7B115%20%5Ctext%20%7B%20yards%20%7D%3D115%20%5Ctimes%203%20%5Ctext%20%7B%20feet%20%7D%3D345%20%5Ctext%20%7B%20feet%20%7D%7D%5Cend%7Barray%7D)
Now, 345 feet > 227 feet
Which means, Distance covered by Rachel > Distance covered by Beth
Thus Rachel ran more than Beth. Hence, Rachel is correct.
