Answer:
15.31
Step-by-step explanation:
solve both sides separately
6x+78/67-78x
x cancles out
becomes 84/-11
becomes -7.64 rounded
180+270-567
becomes -117
moves -7.64 to other side (divide by other side)
-117/-7.64
becomes 15.31
144 divided by 260 is 60%
Answer:
x^2 -81
Step-by-step explanation:
(x+9)(x-9)
FOIL
first x*x = x^2
outer -9x
inner 9x
last -9*9 = -81
Add them together
x^2 -9x+9x -81
Combine like terms
x^2 -81
So she cuts them so each one has 8 since there are two there will be 16 pieces
Out of those 16 she uses 12
So the fraction would be 12/16
But wait! We need to simplify it
Half it
6/8
Half it again
3/4
There ya go!

9:35
If the hour hand is between 9 and 10, that would be 9 still, and if the minuet hand was on 7, it would be 35 because each big number goes by 5, if that makes sense. If not, at least you got the answer
