Answer:
Step-by-step explanation:
24% of 315
= 24/100 × 315
= 0.24. × 315
= 75.6
At its neutral state, an element has equal number of protons and electrons. If not, they occur as ions. The most stable elements are the noble gases. The nearest noble gas to Lithium is Neon, which is one proton lower than Lithium. Hence, when Lithium has a charge, it is naturally +1 because it has to give one electron to be as stable as Neon.
Standard form is ax + by = c.
To change y+2 = 3(x-2) into that form, do:
y+2-2 = 3x -6 -2
-3x + y = -8
Which is not in the list, so none of the answers are right...
