If you work out the fraction of 1600 that 640 you can apply this to the number of 6s, that she based this off of.
640÷1600=0.4
To calculate the number of times she rolled the dice you do 8÷0.4=20.
Therefore she rolled the cube 20 times to get 8 6s.

Answer:
x =
Step-by-step explanation:
Given
8 - (5 - 9x) = 7(1 - x) ← distribute parenthesis on both sides
8 - 5 + 9x = 7 - 7x
3 + 9x = 7 - 7x ( add 7x to both sides )
3 + 16x = 7 ( subtract 3 from both sides )
16x = 4 ( divide both sides by 16 )
x = =
Answer:
x= 50°
Hope it helps!
Step-by-step explanation:
The sum of the exterior angles of a polygon is always 360°
So, x+40+x+20+2x+2x = 360
6x + 60= 360
6x = 360-60 = 300
6x= 300
x= 300/6
= 50
