Answer:
The regular price of the ticket was $12.
Step-by-step explanation:
Let us call
the regular price of the tickets, and if she had bought tickets at this price, the total cost would have been
.
But Holly got $4 off the regular ticket price, that means one ticket cost her
and if she bought 23 tickets it cost her

and we are told this equals $184; therefore we have

now we solve this equation the following way:





Thus, the regular price was $12.
The answer is -
(32,19)

I prefer using the RREF function to put the augmented matrix into reduced row-echelon form. If the equations are dependent or inconsistent, using that method tells you so without giving a matrix inversion error.
Answer:
The cube with surface area of 0.3 sq. meters will exert more pressure.
Step-by-step explanation:
Pressure is given by 
Since mass(m) and acceleration (a) for both the cubes are equal and the area varies, we will have to base our answer on the area.
In the formula for pressure, we can see that Pressure and Area are inverse of each other <em><u>(given mass * acceleration is constant, in this case).</u></em>
So the cube that will exert more pressure is the one with less surface area <u><em>(pressure and area are inverse of each other).</em></u>
Hence the cube with surface area of 0.3 sq. meters will exert more pressure.
