question 20
40 gallons, 12 concentrate, 28 water
this is a fraction of 12/28
simplification: (12) divided by 12 / (28) divided by 12
1/2
1 part concentrate 2 parts water per each of the 40 total gallons.
so color in 33% for concentrate and 66% water
I am totally not wrong :D:D:D:D

Answer:
Television = $200 and DVD player = $450
Step-by-step explanation:
→ Make 2 equations
Televisions = t and DVD players = d
2t + 3d = 1750
4t + d = 1250
→ Multiply the bottom equation by 3 to make the same variable of d
2t + 3d = 1750
12t + 3d = 3750
→ Minus the two equations to isolate the d variable
-10t = -2000
→ Divide both sides by -10 to find the cost of one television
t = 200
→ Substitute t = 200 back into 4t + d = 1250
800 + d = 1250
→ Minus 800 from both sides to isolate d
d = 450
