If you add Hillary to the friend count, that's 24. So there are 16 boys and 8 girls
Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.
Let's substitute b-2 into the first equation wherever there is an a.
a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3
Now let's find a by substituting -3 into either of the equations to find the value of a.
a = b - 2
a = -3 - 2
a = -5
So your solution set is (-5, -3)
J is between H and K.if HJ =4t -15 ,JK=5t-6, and KH=15,find JK.
For this case we have that by definition, the volume of a cube is given by:

Where,
- <em>s: Side of the cube
</em>
We have that the cube side is given by:

Therefore, replacing values we have:

Answer:
One way to write the volume of the cube is:

It would have 5 tails because it was flipped 5 times and had 0 heads
