I think 7x-y=-2 is the answer
Answer:
x=-2
y= 8
Step-by-step explanation:
Given data
10x – 2y = -36-----------1
7x – 2y = -30--------------2
-Subtract to eliminate y
3x-0= -6
3x= -6
x= -6/3
x= -2
Put x= -2 in
7(-2)– 2y = -30
-14-2y=-30
-14+30=2y
16=2y
y= 16/2
y= 8

Answer:
24 Bricks.
Step-by-step explanation:
We know the radius is 6 feet and that the diameter is twice that.
We also know the radius is 12 'bricks' in length.
If we divide both numbers by 12, we get that 1 'brick' is half a foot.
Since that's the radius and we want the diameter, we multiply the radius by 2 to get the diameter.
This results in 12 feet, or 24 'bricks'.
