So, adding a negative number is the same as subtracting.
4-3+5-2
Then if you want, you can use the associative property.
(4-3)+(5-2)
1+3
4
Answer: 5
Step-by-step explanation: There are 2.5 cm per in, so its just 2.5*2

Answer
<h2>
4</h2>
Step-by-step explanation:
Given,
r = 10
Let's create an equation,
![3r = 10 + 5s](https://tex.z-dn.net/?f=3r%20%3D%2010%20%2B%205s)
plugging the value of r
![3 \times 10 = 10 + 5s](https://tex.z-dn.net/?f=3%20%5Ctimes%2010%20%3D%2010%20%2B%205s)
Multiply the numbers
![30 = 10 + 5s](https://tex.z-dn.net/?f=30%20%3D%2010%20%2B%205s)
Move 5s to L.H.S and change its sign
Similarly, Move 30 to R.H.S and change its sign.
![- 5s = 10 - 30](https://tex.z-dn.net/?f=%20-%205s%20%3D%2010%20%20-%2030)
Calculate
![- 5s = - 20](https://tex.z-dn.net/?f=%20-%205s%20%3D%20%20-%2020)
The difference sign ( - ) should be cancelled on both sides
![5s = 20](https://tex.z-dn.net/?f=5s%20%3D%2020)
Divide both sides of the equation by 5
![\frac{5s}{2} = \frac{20}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5s%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B20%7D%7B5%7D%20)
Calculate
![s = 4](https://tex.z-dn.net/?f=s%20%3D%204)
The value of s is 4.
Hope this helps..
Best regards!!
Or, is it asking you to subtract the? In that case
5/4 - 3/8 = 7/8
