Answer:
The answer is 5f + 6g +12
Step-by-step explanation:
I don't know what the "six-step method" is, but I do know how to solve the problem:
Let x = number of gallons of 50% solution
amount of antifreeze in 50% solution = 0.50x
amount of antifreeze in 10% solution = 0.10(80) = 8
amount of 40% solution = 0.40(x+80) = 0.40x + 32
Then, 0.50x + 8 = 0.40x + 32
0.10x = 24
x = 240 gal

Answer:
The answer is 8 feet.
Step-by-step explanation:
Let x = height where the ladder hits the building
7 squared+x squared=25 squared
49+x squared=625
x squared=576
x=24 feet
Let x = distance from wall:
x^2 + 20^2 = 25^2
x^2 + 400 = 625
x^2 = 225
x = 15 feet
(5/6) / (1/5) =
Invert the second fraction then multiply.
(5/6) x (5/1) =
25/6 = 4 + 1/6 Servings
