Answer:
54$ is the final selling price of the camera
is the original fraction
let the denominator of the original fraction be n, then
is the original fraction
adding 2 to the numerator gives
= , hence
= ( cross- multiply )
7(n - 2) = 5n
7n - 14 = 5n ( subtract 5n from both sides )
2n - 14 = 0 ( add 14 to both sides )
2n = 14 ( divide both sides by 2 )
n = 7
original fraction = =
Answer:
tridecagon/triskaidecagon
Explanation:
sum of interior angles= <span>180<span>(n−2)</span></span> degrees, n being the number is sides in the polygon.
sum of interior angles= 1980
<span>180<span>(n−2)</span>=1980</span>
divide by 180:
<span>n−2=<span>1980180</span>=11</span>
add 2:
<span>n=11+2=13</span>
If a polygon has 13 sides, it is called a tridecagon or a triskaidecagon.
16 divided by 125 is .128
125 plus 75 is 200
.128 multiplied by 200 is 25.6 days

148-56 would give u h I think
