2. Add 0 at the end of 5.6, becoming 5.60
3. Here is the problem you now solve:
-1.02 + 5.60. You can simply type this into your calculator. I hope this helped.
Answer:
-2n²
Step-by-step explanation:
Using the image attached:
We see that the second differences (blue ones) are all equal so we conclude that this is a quadratic sequence.
The quadratic sequence has the form:
To find the value of a we just divide second difference ( -4 ) by 2:
Now we have:
Substitute and into the equation above:
Since = -2 and = -8 , after simplification we have:
The solution of this system is:
The general term is :
Answer:
5?
Step-by-step explanation:
2x › 5 (buy at least 4)
so you can just start plugging numbers in.
I used 5, 5 times 2 is 10 which is 5 more that 5, which does met the quota.
So you need to divide 1000 by 125 which is 8. Which then you times by two to equal the two kilograms. So he needs to fill the cup up 16 times.
First multiply 57 x 30, then 30 x .35, then Ta da you have your answer (which is 598.5)
