Answer:
Below in bold.
Step-by-step explanation:
3x + y = -1
2x + y=0
Subtract to eliminate y:
3x - 2x + y - y = -1 - 0
x = -1
So, substituting for x in the first equation;
3(-1) + y = -1
y - 3 = -1
y = 2.
The solution is the ordered pair (-1, 2).
The system is a pair of straight lines which intersect at the point (-1, 2).
Answer:

Question 2 is b.48
Question 3 is a.20 L
Hi there!
First, we need to determine the volume.
1/2 × 2 × 7/2 = 7/2 in cubed
3.5 cubes with sidelengths of 1in can fit in, since both units are three dimensional and 7/2 ÷ 1 = 3.5
7 cubes with sidelengths of 1/2 can fit because 7/2 ÷ 1/2 = 7
Hope this helps!
