Answer:
650,000,000
Step-by-step explanation:
6.5x10^8
Answer:
n=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
11−8n=1−3n
11+−8n=1+−3n
−8n+11=−3n+1
Step 2: Add 3n to both sides.
−8n+11+3n=−3n+1+3n
−5n+11=1
Step 3: Subtract 11 from both sides.
−5n+11−11=1−11
−5n=−10
Step 4: Divide both sides by -5.
−5n
−5
=
−10
−5
n=2
Answer:
During the early days of mathematical expressions the Greeks needed a shorthand form of representing the summation of several terms hence the choice of ∑ as a sigma Notation.
Step-by-step explanation:
The summation symbol ∑ is the upper case equivalent of capital S in Greek and S represents sum in English.

Hello
a=2, b=7, c= -30
ac=-60
-60= 12*(-5)
We can see that 12*(-5)=ac and 12-5=b=7
So

Thanks
