Example 1: Solve the system of equations by elimination
Elimination Method Example
Solution:
In this example we will "cancel out" the y term. To do so, we can add the equations together.
Elimination Method Solution
Now we can find: x = 2
In order to solve for y, take the value for x and substitute it back into either one of the original equations.
Elimination Method Solution
The solution is (x, y) = (2, 1).
Answer:
maybe its so we can easily find the relationships between the numbers
Step-by-step explanation:
Answer:
Last week Gullian walked 10 minutes more than Nancy.
Step-by-step explanation:
1. Nancy walk 50 minutes each day for 4 days last week, then the total number of minutes Nancy walked is
2. Gullian walked 35 minutes each day for 6 days last week, then the total number of minutes Gullian walked is
3. Since 
than last week Gullian walked 10 minutes more than Nancy.
Answer:
615.75216
Step-by-step explanation:
A=πr2
=π·14^2
≈615.75216
So the solid consist of 1 pentagon, 5 congruent equilateral triangle and 5 congruent squares and has 11 vertices so the number of edges of this solid is 20. I hope you are satisfied with my answer and feel free to ask form more if you have more clarifications.
