Since 0.8 is the tenths place, and it is rounded from .799, it is to the tenths place. If the answer was written as .80, it would be to the hundredths place, as that would specify more accuracy in this answer.
Given:
Denver can plant 3 rows of a certain length with 2 seedlings leftover or 4 rows of the same length with 3 seedling spots left empty.
To find:
The equation for the given problem and its solution.
Solution:
Let x be the length of each row.
Denver can plant 3 rows of a certain length with 2 seedlings leftover.
Total number of seeds he has =
...(i)
Denver can plant 4 rows of the same length with 3 seedling spots left empty.
Total number of seeds he has =
...(ii)
Using (i) and (ii), we get
![3x+2=4x-3](https://tex.z-dn.net/?f=3x%2B2%3D4x-3)
Isolate variable terms.
![2+3=4x-3x](https://tex.z-dn.net/?f=2%2B3%3D4x-3x)
![5=x](https://tex.z-dn.net/?f=5%3Dx)
Therefore, the required equation is
and the values of x is 5. Each row is 5 meters long.
Answer:
31.4
Step-by-step explanation:
So a really easy way to solve this is as goes
--> 3.14 x (20 x 1/2)
--> 3.14 x (10)
Now multipling by 10 is just moving the deciaml place one spot to the right
=> thus, we get 31.4
Hope this helps!
Answer:
11a-8
Step-by-step explanation:
Please Note that i assume 12a and 2 are positive.
(12a+2−8a+4)-(12−7a+2)
=12a+2-8a+4-12+7a-2
=12a-8a+7a+2+4-12-2
=11a-8
