Step-by-step explanation:
2 times 10^4 means 2 with 4 zeroes after it or 20000
4 times 10^6=4 with 6 zeros after it or 400000
compare
20000 and 4000000
we can see that 4000000 is 200 times of 20000
therefor the answer is C
we can also do
(4 times 10^6)/(2 times 10^4)=4/2 times (10^6)/(10^4)=2 times 10^2=200
answer is C
Answer:
x=1/7 or 0.14
Step-by-step explanation:
first you distribute: 8-6x+2=x+9
next combine like terms (8 and 2): -6x+10=x+9
then subtract 1x from both sides: -7x+10=9
then subtract 10 from both sides: -7x=-1
divide both sides by -7: x=1/7 or 0.14
