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: $1.5
Step-by-step explanation: 5.25 divided by 3.5
-4x+2y=24 is in standard form.
2y=4x+24
y=2x+12 is slope form reduces
y=mx+b
m=2 b=12
There is no choice for the correct answer
We are tasked to determine the difference between the two expressions such as 9+3x and 4+2x². In order for us to solve this, we need to arrange the terms in descending order such as shown below:
(3x + 9) and 2x² + 4
Then, we need to perform subtraction in the same terms only such as 9 and 4:
3x +9 - (2x² + 4)
3x + 9 -2x² - 4
3x + 5 - 2x²
Then arrange in descending order such as:
2x² + 3x + 5
The answer is 2x²+3x+5.
