The given expressions 7+ 7x ; 7 x + 1/7 are not equivalent or equal

to each other

Step-by-step explanation:

Let us firstly assume that 7 + 7x is equivalent ( to 7(x + 1/7) so that means

7 + 7x = 7(x + 1/7)

7 + 7x = 7x + 7(1/7)

7 + 7x = 7x + 1

7x + 7 = 7x + 1

Now, subtracting 7x from both sides, we get:

7x - 7x + 7 = 7x - 7x + 1

(7 - 7)x + 7 = (7 - 7)x + 1

(0)x + 7 = (0)x + 1 thus their occurs a false statement:

7 = 1 ( we know, 7 >1)

Thus we can say that

7 + 7x is NOT equivalent to 7(x + 1/7)

Solve for n. 4 x n= 21.6

Kay [80]

Answer:

n = 5.4

Step-by-step explanation:

Equation: 4n = 21.6

To solve this equation for n, divide both sides by 4 to get n by itself.

Step 1: Divide both sides by 4

4 * n / 4 = 21.6 / 4

n = 5.4

Answer: n = 5.4

The corcumference C of a circle is C= 2 x pie x radius
So radius= C/(2pie)
