8(4n + 13) = 6n
Use distributive property so :8 (4n) = 32n and 8(13) = 104
32n + 104 = 6n
Subtract 32n from each side and you will get:
104 = 26n
then you divide each side by 26 and your answer will be:
n = 4
Try this:
21/7=3
multiply 3x2
x=6
y=21 x=6
or...
7/2=21/x
cross multiply to get 7x=42
divide by 7 and x=6
Answer:
a circle with a diameter of 16 meters largest
a circle with a circumference of 37.68 meters
a circle with a radius of 7 meters
a circle with a diameter of 8 meters
Step-by-step explanation:
a circle with a diameter of 8 meters
The radius is 8/2 = 4
A = pi r^2 = 3.14 * 4^2 = 50.24 m^2
a circle with a radius of 7 meters
A = pi r^2 = 3.14 * 7^2 = 153.86 m^2
a circle with a circumference of 37.68 meters
C = 2*pi*r
37.68 = 6.28r r =6
A = 3.14 (6)^2 =113.04
a circle with a diameter of 16 meters
r = d/2 = 8m
A = pi r^2 = 3.14 (8)^2 = 200.96 m^2
He will have 8 fields in the total area of his land.
<u><em>Explanation</em></u>
Both length and width of each square field are mile
So, the area of each square field square mile.
Total area of the land bought by the farmer is square mile.
For finding the number of fields, we need to <u>divide the total area of land by the area of each field. </u>
So, the number of fields = ÷ = × = = 8
