Answer:
≈ 1833
Step-by-step explanation:
To find ratio of proton mass to electron mass, we have to divide.
The numbers are given in <em>scientific notation</em>.
Let a number be 
and another be 
, when we divide, we will follow the rule shown below:
Now, we use the information given to find the ratio:
This means we can find the number by taking 4 decimal places to the right, so that would becomes:
The approximate ratio is 1833 [mass of proton is around 1833 times heavier than mass of electron]
Answer:
5x+22
Step-by-step explanation:
8x-3x = 5x
13+9 = 22
Remember sign stays with the number
Answer:
y - 5 = -3(x - 12)
Step-by-step explanation:
Point slope form is: y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope of the line.
Plug in the point and the slope:
y - y1 = m(x - x1)
y - 5 = -3(x - 12)
So, y - 5 = -3(x - 12) is the equation in point slope form of the line.

Step-by-step explanation:
Answer:
-10
Step-by-step explanation:
3x^2 - 2(3y + 2x)
3(-2)^2 - 2(3(5) + 2(-2))
3*4 -2( 15-4)
12 -2(11)
12-22
-10
