Answer:
A
Step-by-step explanation:
empirical formulas are the simplest form of notation so they provide the lowest whole number ratio between the elements in a compound
Yup, the amount of 0's is the exponent. for example 1000= 10^3, hope this helped :)
You can use the regrouping
<span>This one is the correct answer----->Multiply the bottom equation by 2 thus eliminating the y variable when the equations are added together.
</span><span>X + 6y = 2 ....top
</span><span>4x - 3y = 10...bottom
if we multiply the bottom equation by 2 .......... => 8x - 6y = 20
if we add it to the top one..........>(8+1)x +(6-6)y = (20+2)
then we solve for x => x = 22/9
then with the top equation, we solve for y == > y = -2/27</span>
