Answer:
£349.35
Step-by-step explanation:
okay so firstly add the % to 100 = 170
then do 170 divided by 100 and multiply by the total ($205.50)
this would give you $349.35 <----- this is your orignal price (before the sale 70% off)
£4 = 400p. 400p divided by 10 is 40p, which means 40p is the price of one pen. 40p x 7 is the price of 7 pens, which is 280p.
Subtract 42 from 44.92 and then divide by 42. So it is 7%
The interior angle of a regular polygon is equal to 180(n - 2)/n. The exterior angle is always equal to 360/n. Using the given relationship from the item above, the equation that can be formed is,
180(n - 2)/ n = 3(360/n)
The value of n from the equation is 8. The polygon with 8 sides is an octagon.
<em>Answer: OCTAGON</em>
Answer:
x = 13 1/2
Step-by-step explanation:
16x -12x+0=54
combine like terms
4x + 0 = 54
4x = 54
divide each side by 4
4x/4 = 54 /4
x = 54/4
x = 13 2/4
x = 13 1/2
