Help please pleassse​
ASHA 777 [7]

Answer:

n=\frac{8}{3}  or  n = 2\frac{2}{3}

Step-by-step explanation:

Multiply both sides of the equation by \frac{10}{3}

(\frac{10}{3}) (\frac{3}{10})*n= (\frac{10}{3})(\frac{4}{5})

Simplify both sides of the equation.

n=\frac{8}{3} or n = 2\frac{2}{3}

<em>hope this helps :)</em>

A fair coined is flipped what is the probability it will land on its head
Georgia [21]
For example, the probability of an outcome of heads on the toss of a fair coin is ½ or 0.5. The probability of an event can also be expressed as a percentage (e.g., an outcome of heads on the toss of a fair coin is 50% likely) or as odds (e.g., the odds of heads on the toss of a fair coin is 1:1).

In a regular polygon each interior angle is 140° greater than each exterior angle. Calculate the number of sides of the polygon​
pochemuha

Answer:

18 sides.

Step-by-step explanation:

The interior and exterior angles sum to 180 so:

       I + E = 180

also  I - E = 140       (given)

So, adding to eliminate E:

      2I = 320

I = 160 degrees and the external angle E = 1809 - 160 = 20 degrees.

Since the sum of all exterior angles in a polygon = 360 degrees

- the number of sides = 360 / 20 = 18.
