Answer:
The solution is obtained by adding the two equations.
The solution is: (x, y) = (,
)
Step-by-step explanation:
We are given two equations with two variables. The strategy is to eliminate one variable and solve for both the variables.
The two equations are:
Adding both the equations, we get:
Substituting the value of 'x', we get the value of y.
We substitute in (2). [Can be substituted in any equation].
We get: y = 2x - 1
So, we get the corresponding values of x and y which is the solution of the two equations.
In step 2, V = show the error in volume work.
Solution:
Given data:
The steps shows it is sphere.
Radius of the sphere = 12.5
The value of π = 3.14
Volume of the sphere =
Step 1:
Step 2:
Step 3:
Step 4:
V = 8177.08 cubic units
This is the correct solution.
But in the given options, in step 2, 12.5 is multiplied by 3.
That is not the correct step. You have to do 12.5 × 12.5 × 12.5.
Hence in step 2, V = show the error in volume work.
