3x -1/2y = -7/2
x = -2y + 1
3 (-2y + 1) -1/2y = -7/2
-6y +3 -1/2y = -7/2
-13/2y = -13/2
y = 1
x = -2(1) + 1
x = -1
Answer = (-1, 1)
Answer:
1. 50%
2. 3%
3. 20%
4. 200%
Step-by-step explanation:
Here, we want to find the worth of each coin as a percentage of $1
We simply divide the worth by $1 and multiply by 100%
$1 is same as 100 cents
Thus;
1. 50 cent
= 50/100 * 100% = 50%
2. 3 cents
= 3/100 * 100% = 3%
3. 20 cents
= 20/100 * 100% = 20%
4. $2
= 2/1 * 100% = 200%

Answer:
1 cubic unit will be the volume of the prism.
Step-by-step explanation:
Volume of the triangular prism = 27 cubic units
Since formula of volume of the triangular prism = (1/3)A×h
27 = (1/3)A×h ⇒ Ah = 27×3 = 81
Now each side of the prism is dilated then we have to calculate the volume of new prism.
V' = (1/3)×A'×h'
= (1/3) (1/9)A×(1/3)h = (1/81)×Ah = (1/81)×81 = 1 cubic unit
Therefore the volume of new prism will be 1 cubic unit
