Solve the following system of equations using elimination
NARA [144]

Answer:

Well elimination is basically multiplying a number to make it possible for it to cancel out

We can multiply the first equation by 2

2(x+2y=-1)

This would be

2x+4y=-2

Its still the same thing but just with non simplified numbers

We can now do any method really to solve

I will just do the subtraction method

2x+4y=-2

-2x+y=4

Solve

2x-2x=0

4y-y= 3y

-2-4= -6

3y= -6

Now solve

y=-2

To find x subsitute in “y” and find ”x”.

x+2*-2=-1

x-4=-1

x=3

y= -2

x= 3

I'm pretty sure you're supposed to use Pythagorean Theorem, so here goes:
a^2+b^2=c^2
=8^2+b^2=10^2
=64+b^2=100
=b^2=100-64
=b^2=36
=b=6
So, AD=6
Then, 6*2=12
AC=12cm

Please help. For each box, just number them. Example: The top box is 1, the middle box is 2, and the third box is 3.
Feliz [49]

Answer:

box 1=4

20/5= 4 (if you divide the others by x and y they equal 4)

box 2=512

if every square mile has 4 squirrels. then you multiply 128×4=512

box 3=81 because you divide 324/4=81
