Answer: energy produced in the core travels through out the gases of Sun and takes about million years to reach its surface
Explanation:
I believe the answer to this is B
The correct answer is this one: "C) Nnew = Nold + 2." A student is studying a process in which a diploid cell becomes haploid. The CORRECT mathematical model for the process if Nnew is the number of chromosomes in the haploid cell and Nold is the number of chromosomes in the diploid cell is this: <span>new = Nold + 2
</span>
Here are the choices.
<span>A)
Nnew = 2·Nold
B)
Nnew =
Nold
2
C)
Nnew = Nold + 2
D)
Nnew = Nold × 2</span>
Answer:
x=6/7, y=-228/35
Explanation:
-4x+5y = -36 /*3
15x-3y = 32 /*5
------------------------- here we multiply both equations to get common y
-12x+15y = -108
75x-15y = 160
------------------------- then we add these two equations to eliminate the y
-12x+75x+15y-15y = 54
63x = 54
------------------------- then we get the x
x = 54/63
x = 6/7 (after we divide both with 9)
------------------------ next up, we add the value of x in first equation
-4 * 6/7 + 5y = -36
-24/7 + 5y = -36
------------------------ we leave 5y on the left side
5y = -36 + 24/7
5y = -252/7 + 24/7
-------------------------- common divider is 7 so we multiply 36*7=252
5y = -228/7
y= -228/7/5/1
------------------------- now we leave only y on the left side
y = -228*1/7*5
y = -228/35
------------------------- when dividing the fragment we multiply outer and inner
