3x + 2y = 6 ⇒ -3x - 2y = -6
-x + y = -2 ⇒ <u>-3x + 3y = -6</u>
<u>-5y</u> = <u>0</u>
-5 -5
y = 0
3x + 2(0) = 6
3x + 0 = 6
<u> - 0 - 0</u>
<u>3x</u> = <u>6</u>
3 3
x = 2
(x, y) = (2, 0)

Answer:
I think it's AB
Step-by-step explanation:
Since its the opposite of AD
A measurement of 0.6 grams means that the 'true' answer lies between
<span>0.55 and 0.65 </span>
In general, the uncertainty in a single measurement from a single instrument is half the least precise decimal given for the instrument.
The precision for this measurement is in the tenths place.
so we take 0.1 /2 = 0.05, and divide by the measurement
<span>0.05 / 0.6 = 0.08333 = 8.3 %</span>
