If you could write out the whole problem exactly how it is, I can solve it for you.
A postulate is an assumption we use for mathematical reasoning; it isn't yet proven. once it's proven, it becomes a theorem.
Answer:
430 billion (430,000,000,000) is 4.3 x 10^11 in scientific notation
400 to 400-60 which is 340
Does this helps you?
I hope it does but tell me if it doesn't.
X + x + 10 + x + 20 + x + 30 = 84.
4x + 60 = 84.
84 − 60 = 24
4x = 24.
24 / 4 = 6 = x.
