4 more than one third of a number n is 6. An equation is? The solution is n =?
harkovskaia [24]

Answer:

 \frac{1}{3}n  + 4  = 6  

6

Step-by-step explanation:

Given problem:

      4 more than one third of a number n is 6

Unknown:

The equation = ?

Solution of the number  = ?

Solution:

 let the number  = n

So, 4 more than one third of a number;

  One third of n = \frac{1}{3}n

  4 more;

                \frac{1}{3}n  + 4

   is 6;

             \frac{1}{3}n  + 4  = 6   (equation of the expression)

Let us now solve the equation:

                         \frac{1}{3}n  + 4  = 6  

                    \frac{1}{3}n = 6 - 4

                   \frac{1}{3}n = 2

                     n = 6

Otrada [13]
The answer is

The diameter is 4 (2) = 8 and height is 10(2) = 20

For the sides, use area of a cylinder = ph

p = 8 pi cm, ht = 20 cm. A = 160 pi sq cm

Base are 2 circles, each with radius 4 pi

Area = pi r^2 = 16 pi (times 2 circles) = 32 pi sq cm

That is weird but here it is again
borishaifa [10]

Answer: 3.6 feet per year

Pick any column and divide the feet over the years

eg: 7.2/2 = 3.6 (column 1)

You can think of it as the ratio

7.2 feet: 2 years

and then divide both sides by 2 to get "1 year" on the right side

7.2 feet: 2 years

7.2/2 feet: 2/2 years

3.6 feet: 1 year
