L.C.M. of the denominators is 10.
So, keep the denominators and subtract the numerators.
![\frac{5}{10} -\frac{3}{10} =\frac{5-3}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B10%7D%20-%5Cfrac%7B3%7D%7B10%7D%20%3D%5Cfrac%7B5-3%7D%7B10%7D)
![=\frac{2}{10}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2%7D%7B10%7D)
Now, simplify the fraction.
To simplify, divide the numerator and the denominator by the common factor 2.
![\frac{5}{10} -\frac{3}{10} =\frac{2}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B10%7D%20-%5Cfrac%7B3%7D%7B10%7D%20%3D%5Cfrac%7B2%7D%7B10%7D)
![=\frac{1}{5}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1%7D%7B5%7D)
Hence,

Answer:
![\huge\boxed{\sf 3(n + 5) \leq 100}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7B%5Csf%203%28n%20%2B%205%29%20%5Cleq%20%20100%7D)
Step-by-step explanation:
- The sum of a number n and 5 => n + 5
- Thrice the sum of a number n and 5 => 3(n + 5)
- At most means "less than or equal to", the sign of which is "≤"
<u>So, the inequality will be:</u>
3(n + 5) ≤ 100

Answer:
![\sqrt{29}\ units](https://tex.z-dn.net/?f=%5Csqrt%7B29%7D%5C%20units)
Step-by-step explanation:
we know that
In a right triangle
Applying the Pythagorean Theorem
![c^2=a^2+b^2](https://tex.z-dn.net/?f=c%5E2%3Da%5E2%2Bb%5E2)
where
c is the hypotenuse (the greater side)
a and b are the legs (perpendicular sides)
In this problem we have
![a=2\ units\\b=5\ units](https://tex.z-dn.net/?f=a%3D2%5C%20units%5C%5Cb%3D5%5C%20units)
substitute
![c^2=2^2+5^2](https://tex.z-dn.net/?f=c%5E2%3D2%5E2%2B5%5E2)
![c^2=29](https://tex.z-dn.net/?f=c%5E2%3D29)
![c=\sqrt{29}\ units](https://tex.z-dn.net/?f=c%3D%5Csqrt%7B29%7D%5C%20units)
