The answer would be a 28% decrease.
Hope that helps!!
Bought lines need to pass same point, so:
x+12 = y = y = 3x+2
x+12=3x+2 |-2
x+10=3x |-x
10=2x |/2
5=x
x+12 = y => 5+12 = y =>y = 17
(x,y) => (5,17)
Answer:
6
Step-by-step explanation:
P=2(L+W)
74=2(31+W)
74=62+2W
2W=74-62
W=12/2
W=6
Answer:
Amount of chemical solution = 18 gallon
Amount of pure water = 22 gallon
Step-by-step explanation:
Assume;
20% of solution = x
So,
Amount of pure water = 40 gallons - x
Amount of pure water = 40 - x
Computation:
20% of x = 9% of 40 gallon
0.2 x = 3.6
x = 3.6 / 0.2
x = 18 gallon
So,
Amount of chemical solution = 18 gallon
Amount of pure water = Total solution - Amount of chemical solution
Amount of pure water = 40 -18
Amount of pure water = 22 gallon
