Answer:
-1/6
Step-by-step explanation:
A suitable calculator can evaluate this for you and show you the result as a fraction.
You start with the multiplication in the inner-most set of brackets. Here, those brackets are the absolute value function.
-2(-1/3) = +2/3
Then the sum in those brackets:
-5/6 +2/3 = -5/6 +4/6 = -1/6
The absolute value changes the sign of this back to positive, so the value in square brackets is ...
3 -(1/6) = 18/6 -1/6 = 17/6
Finally, this value is divided by -17, so you have ...

Answer:
I'm pretty sure it's +(-6).
Step-by-step explanation:
Basically for these, you find the slope. The slope equation is y1-y2/x1-x2.
Pick two points.
I'll just do (1,15) and (2,9).
15-9/1-2 = 6/-1 = -6.
I don't know if you were taught it this way, but my math teacher always told us that the rate of change had to be positive.
So you'd say the rate of change is +(-6), not -6.
Hope that sorta helped lol
X = 4/3 because set y=0.
so 0=3x-4. add 4 to both sides so
4=3x. divide both sides by. 3 and you get x=4/3.
Answer:
Consider the number of children to be x.
So, 144 coins were divided amongst x children.
For x-3 children, each child would have 16 coins
So, (x-3)*16=144
Solving for x, x-3=144/16
or x-3=9
or x=9+3=12
Answer is 12
