The common difference is basically the second number minus the first (or the 3rd-2nd, and so on). The answer should be B.
Answer:
-7
Step-by-step explanation:
3 v + 2 x
3 ( - 1) + 2 ( -2)
-3 - 4

<span>b.9 x 10^4 is 18 times larger than 5 x 10^3
This is a simple matter of floating point division. So let's do that.
9 x 10^4 / 5 x 10^3
First, divide the significands. Giving
9 / 5 = 1.8
And subtract the exponents
4 - 3 = 1
So the result of the division is
1.8 x 10^1 which is 18. So 9x10^4 is 18 times larger than 5x10^3. Now looking at the available options, it's obvious that only "b" is correct.</span>
answer:
=1
explanation:
you need to add the exponents, so 5-5= 0 and a number to the 0 is 1
Answer:
x = 10
Step-by-step explanation:
1/3 (2x - 8)=4.
Multiply each side by 3
1/3 *3(2x - 8)=4.*3
2x-8 = 12
Add 8 to each side
2x-8+8 =12+8
2x = 20
Divide each side by 2
2x/2= 20/2
x = 10
