-12 + 5(3) = total yards at the end
So your answer would be 3 yards
So, here you have to look at the periodic table and see what the molar mass of each molecule composing the water compound

its two hydrogen atom plus an oxygen molecule, making it about 18g per mol.
That said, looking at the mass, we have to ask ourselves, if a mol of water contains 18g of mass, how many moles do we have in 0.5g of water?
We just do a cross multiplication:
Answer:
One interior angle is 50°.
Exterior angle is 95°.
Step-by-step explanation:
(x-3)=-3x+25
Because we know that y=x-3 so we put that in place of y in the equation
My explanation is attached below.
