Yay thank you!

I don't rally know why the sky is blue but I think it's because the ocean is. The ocean reflects the color of the sky and sky reflects the color of the ocean. I don't really know though. Hope this helps! :)

Answer:

a. $x^{2} + 3y^{3}$

b. $3y^{3} -6$

c. $5x -3$

d. -6t - 5

Step-by-step explanation:

When a number has the same variable as another, you can add or subtract them

So for the first one, you can do

$5x^{2} -4x^{2} = 1x^{2} = x^{2}$

(But don't forget the $3y^{3}$ !)

So it is:

$x^{2} + 3y^{3}$

Continue this process for the rest of them

4x + 3y = 6 3x + 5y = -1 Solve the simultaneous equations. y= z=

Kisachek [45]

Answer:

x=3, y= -2

Step-by-step explanation:

Multiplying :

(4x+3y =6)*-3

(3x+5y =-1)*4

-12x -9y= -18

12x+20y= -4

Add the equations

20y-9y = -4-18

11y = -22

y= -22/11 = -2

3x +5* -2= -1

3x -10 = -1

3x = 10-1

x= 9/3 =3
