Answer:
if we are simplifying, the answer is 6x⁴y²
Please see attached image for the answer
Range: all real numbers
<h3>The answer is:</h3><h2>D. 5 hours</h2><h2 />
The equation should be:
(70x) - (20x) = 250
Because we have all the possible answers, we can plug one of them into x to see if it equals 250 miles.
Use an educated guess. I'm going to go with 5 because it seems reasonable.
(70 * 5) - (20 * 5) = 250
Let's check to see if it equals 250:
Therefore, the answer is D. 5 hours.

Answer:
The volume of the solution with 20% acid is 27 gallons and the one with 10% acid is 18 gallons
Step-by-step explanation:
Myra needs to mix "x" gallons of the solution with 20% and "y" gallons of the solution with 10%. The volume of the final solution must be 45 gallons, therefore:
x + y = 45
The concentration of acid of the final solution is:
0.2*x + 0.1*y = 45*0.16
0.2*x + 0.1*y = 7.2
Therefore we have a system of equation:
x + y = 45
0.2*x + 0.1*y = 7.2
We need to multiply the first equation by -0.1:
-0.1*x -0.1*y = -4.5
0.2*x + 0.1*y = 7.2
We now sum both equation:
0.1*x = 2.7
x = 2.7/0.1 = 27 gallons
y = 45 - 27 = 18 gallons
Answer: the answer is 59,527 is divided by 23, the quotient is 2,588 R 3
the answer is 3 or remainder 3
