Answer: x=-3/5 and y=13/5
Step-by-step explanation:
I really dont want to explain this answer is correct.
True.
Any and all lines that are parallel share the same slope.
Here,
cost of 3 handkerchiefs = Rs.2.29
Cost of 1 handkerchief = 2.29 ÷ 3
= Rs. 0.763
Therefore, cost of handkerchief per dozen = Rs. 0.763 × Rs.12
=Rs.9.156

To get this answer you must add the two equation together, and add together the like terms (Ex. 3t-2t and 5+2)</span>
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have the points (2, 5) and (4, 10). Substitute:
![m=\dfrac{10-5}{4-2}=\dfrac{5}{2}=2.5](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B10-5%7D%7B4-2%7D%3D%5Cdfrac%7B5%7D%7B2%7D%3D2.5)
This means that 2.5mm of rain falls every hour
