Solve everyone of these problem using a method of choice, verify each solution, if the problem does not submit exactly to the solution is it because it submits an infinity or not?
( substitution, elimination)...

Everyone Can contribute by doing one of the problems so it can be completed.




A)

5x - 3y =9
2x - 5y = -4

B)

3a + b - 4 =0
2a - 10 =3b

C)

x=2-2y
y+1/2x= -1

D)

x/3+y/4= -1
2x+y= -8

E)

3p - 6q=0
4p+q=3

F)

2x+3y= -2
8x+5y= -6

G)

0,2x + 0,7y=1,5
0,3x - 0,2y = 1

H)

x/5 + y/3 = 3
x/2 - y/12 = 2

I)

2(m+1) - (n - 4) = 15
3(m-1) + 4(n+2) = 2

A bear came to my back door and scratched at the door. It did NOT run off when I yelled and pounded back on the door. When I turned on the porch light it ran. Bears were scaring children waiting for the bus each morning on our street so the neighbors applied for a hunting permit so they could kill the bears. They got 5.

I was at the beach today and was thrilled to find hundreds of sea anemones of varying size covering the reefs. My little brother had to poke each and every one with his finger. The anemones don't seem harmed by the experience, but I can't help but think it just isn't right to poke at them like that. Does anyone know if this is actually harmful, or is it just rude?

is it the very very small distance/displacement of a particle in rotational motion or can it be of any distance in the path of the body cause if it is then we cannot compare it with linear motion since neither is the velocity nor the displacement constant during the motion please help im really confused here

think Biology is more important and easier than Chemistry. Biology involve cells, virus, genes, and more. Chemistry deals with polarity, heat, gas, vapor, electronegativity. Which major is better for pre-med?

A lot of people major more in Biology than Chemistry and I wonder why. Is it because its easier or more relative to medecine?

Most readers will have heard of the International Date Line, established as an irregular line, drawn by convention through the Pacific Ocean, substantially along the 180th meridian IDL marks the place where the date changes.

Crossing the line from west to east, travelers gain a day and, conversely, lose a day traveling east to west.

The position of the IDL has been arbitrarily designated and is partly curved to accommodate eastern Siberia, then bulges westward again in order to avoid crossing land.

Let us now assume that a successor of the Concorde can take its passengers around the equator, cicrcling the globe in six hours. Flying west to east it will cross the IDL four times in 24hours and consequently lose four days. Starting, say, in the 18th of March it will land on the 14th of March. Continuing the journey the passengers will go back into history eventually reliving the birth of Christ. Is there something wrong with this reasoning???
