Answer:
Step-by-step explanation:
- Let (applicable to all three lines below)
- Hard candy = x kg with price $1.60/kg
- Gummy worms = y kg with price $2.20/kg
- Total weight = 50 kg with mixed price $1.75/kg
<u>Required equations:</u>
- x + y = 50 total weight
- 1.60x + 2.20y = 50*1.75 total price
=========================================
<u><em>Note</em></u><em>. It says don't solve but the solution below for those who is interested to know the answer.</em>
<u>Simplify the second equation and solve by substitution x = 50 - y:</u>
- 1.6(50 - y) + 2.2y = 87.5
- 80 - 1.6y +2.2y = 87.5
- 0.6y = 7.5
- y = 7.5/0.6
- y = 12.5
<u>Find the value of x:</u>
<u>Hard candy</u> = 37.5 kg and <u>gummy worms</u> = 12.5 kg

Answer:
Line of reflection will be y = -2
Step-by-step explanation:
From the picture attached,
Triangle ABC has been reflected over an unknown line so that the triangle ABC will overlap triangle A'B'C'.
To find the line of reflection,
Coordinates of point C → (7, 0)
Coordinates of point C' → (7, -4)
Line of reflection = line passing through midpoint of the line joining C and C'
Midpoint of the line joining points C and C' = 
= 
= (7, -2)
Therefore, line of reflection is y = -2.
