Well there's 10 decimeters in a meter. That means there's 20 decimeters in 2 meters. Hope this helps.
Answer:
961 yards²
Step-by-step explanation:
A square has all its sides equal
Thus the area of the square is = length ² = 31² = 961
Answer:
The system solution is (20, 0)
Step-by-step explanation:
Let's begin by eliminating x. Multiply the second equation by 2, obtaining
-0.2x + 0.6y = -4, and add this result to the first equation:
0.2x + 0.5y = 4
-0.2x + 0.6y = -4
------------------------
1.1y = 0, so y must be 0.
Substituting 0 for y in the first equation, we get:
0.2x + 0 = 4. Dividing both sides by 0.2, we get x = 20.
The system solution is (20, 0).
For example
We have y=7-3x
y=5-2x
and we want to find where the 2 graphs intersect
we add 3x and 2x in the 2 equations
3x+y= 7
2x+y=5
3x-2x+y-y=7-5
x=2
3*2+y=7
y=7-6
y=1
For x=2, y=1 ⇒ A(2,1) is the point where the 2 graphs intersect
⇒ There is only a point where 2 lines intersect
