Answer:

n = 2 1/14

Step-by-step explanation:

You have the equation (3/7)n = 2 1/14 and need to find the value of n.

First rewrite 2 1/14 as the improper fraction 29/14:

(3/7)n = 29/14.  Here the LCD is 14, so multiply both sides of this equation by that:

14(3/7)n = 14(29/14) = 29.  Simplifying this further, we get 6n = 29, so that:

n = 29/14, or  n = 2 1/14

Find the value of x
Doss [256]

Answer:

x = 40

Step-by-step explanation:

The three angles in a triangle add to 180 degrees

x + 30 + (3x-10) = 180

Combine like terms

4x +20 = 180

Subtract 20 from each side

4x+20-20 = 180-20

4x= 160

Divide each side by 4

4x/4 =160/4

x = 40
