Answer:
(3, -1)
Step-by-step explanation:
The easiest way to solve this system of equations is by elimination:
3x + y = 8
2x - y = 7
Add the two equations together:
(3x + 2x) + (y - y) = (8 + 7)
5x = 15
x = 3
Substitute x back into the equation:
2x - y = 7
2(3) - y = 7
6 - y = 7
- y = 1
y = -1
The fourth option, (3, -1)

Answer: 1848 cubic meters</h3>
=================================================================
Explanation:
Imagine rotating the figure so that the triangular face is flat on the ground. This makes the triangular faces to be the floor and ceiling of this room.
The floor is a triangle with base 24 meters and height 7 meters. The floor area is base*height/2 = 24*7/2 = 84 square meters.
Multiply this floor area with the height of the room (22 m) to get the volume of the room.
volume = (floor area)*(height) = 84*22 = 1848 cubic meters
In physics, string theory<span> is a </span>theoretical<span> framework in which the point-like particles of particle physics are replaced by one-dimensional objects called </span>strings<span>. It describes how these </span>strings propagate through space and interact with each other. ... Thus string theory<span> is a </span>theory<span> of quantum gravity.
