3. Add 4 to each side canceling it out on the left and leaving 10x = 104

4. Divide each side by 10 to get x by itself

5. 10x/100 = 104/10

Delicious77 [7]
21/2 or 10 1/2
Explanation:
8 3/4 is the same as 35/4

so Darcy harvests 35/4 per 5/6 hours
to figure out how much is harvested in one hour, you divide the amount harvested by the amount of hours taken to harvest it.
35/4 ÷ 5/6 =35/4 × 6/5

35/4 × 6/5 = 7/2 × 3/1 = 21/2

so the answer is 21/2 or 10 1/2

Is 9999 in the sequence n²+2n?​
Tamiku [17]

Answer:

No

Step-by-step explanation:

To find out, all we need to do is plug in 9999 into the sequence.

9999 = n^2 + 2n

By completing the square, we get (n+1)^2 = 1001. 1001 is not a perfect square, which means that 9999 is not in the sequence.

hope this helped! :)
