Answer:
there are no graphs
Step-by-step explanation:
but the slope is -2/1
The answer is A,because the way your question is written,there would be 4 molecules of salt (NA) and one molecule of CL (Chlorine)
I’ve attached my work with my answer hope it helps!
We know that 50/200 of the counters have white paint. That is equal to 1/4 of the counters. Since there is an even distribution of the counters, we can guess that 1/4 of the counters taken out have white paint. 1/4 of 80 = 20
We could expect about 20 of the counters taken out to have white paint
We know that a supplementary angle is 180 degrees because they add up to 180 degrees.
To solve for x:
Add the whole numbers
7x + 33 + 70 = 180
Subtract 103 on both sides.
7x + 103 = 180
-103 -103
Divide 7 on both sides to get x alone.
7x = 77
--- ---
7 7
x = 11
Check:
7(11) + 33 + 70 = 180
77 + 33 + 70 = 180
110 + 70 = 180
180 = 180
The angle
7(11) + 33
77 + 33
equals to
110
Which means that the angle is 110 degrees.
