The same reason that you need to have the same amount of weight on both sides of something. It is a part of laws of math, you cant have an unbalanced chemical equation the same way you cant have an unbalanced math equation. You have to look at it like its a physical thing that has properties, not just ink on a paper.
We can't see the angles so we can't help you :(
Maybe take a picture of the problem(or screenshot if it's online) and edit the post.
Answer:
10:1
Step-by-step explanation:
as 6 kg = 6000g
so 6000g /600g
= 10 : 1. { 10 /1)
Answer: (5, -7)
Step-by-step explanation:
On a graph, the solution(s) of two equations is/are the points at which they intersect.
For the graph shown, there is only one intersection point, (5, -7). This set of coordinates satisfies both equations, so it is a solution to the system.
So here's gives that
total weight of 25 bags = 50 x 25
= 1250
total cost of 25 bags weighing 50 kg is = 15000
cost of 1 kg = 15000 ÷ 1250 = 12
now total weight of 15 bags weighing 30 kg = 450
cost per kg = 12
cost of 15 bags weighing 30 each = 450 x 12
Answer = 5400 rupees.
