Answer:
In addition, from the response shown, using a graphical calculator brings the following benefits:
1) You can write the system of linear equations as big as you want. This is: systems 3 * 3, 4 * 4, 5 * 5.
2) The response to systems of equations greater than 2 * 2 can be complicated when you graph the solution, therefore, the graphing calculator can be much more efficient in these cases.
3) You can write the linear equations in any way. Resolving by hand you should probably rewrite the system of equations to find the solution.
Step-by-step explanation:
So for 12.5 meters...the little guy walks 5 meters per minute....
<span><span><span>12.5meters</span><span>5<span><span>meters</span><span>minute</span></span></span></span>=2.5minutes</span>
we can check it by saying...okay...if his speed was 5 meters per minute....and he walked for 2.5 minutes...does he walk 12.5 meters?
<span>5×2.5=12.5</span><span>
so yes it checks out :)</span>
-6 3/4, -6.6, -5 5/8, 27/5, 5.8
Answer:
3/4 divided 4=16 or 0.1875
Step-by-step explanation:
3/4 divided by 4 is easy all you would do is multiply the bottom number by what you are trying to divide which is 4 so you do 4x4 which is 16
Answer:
-4
Step-by-step explanation:
-5x-12=2x
-3x-12=0
-3x=12
3x=-12
x=-4
