2 quarts of 100% antifreeze.
Step-by-step explanation:
5 quarts/ .40 * x/ 1
.40x= 5
x=2
W = 10 ft; l = 50 ft is Correct
w = 90 ft; l = 30 ft is Correct

Step-by-step explanation:
Answer:
x + y = 9.
Step-by-step explanation:
xy = 2(x + y)
xy = 6(x - y)
2x + 2y = 6x - 6y
8y = 4x
x = 2y
Substitute for x in the first equation:
2y^2 = 2(2y + y)
2y^2 = 6y
y^2 = 3y
y(y - 3) = 0
y = 0, 3.
x = 2y = 0 , 6.
As the integers are positive they must be 3 and 6.
x + y = 3+6 = 9.
Answer: 3 - x
Step-by-step explanation: With
Subtraction be careful. 3 - x is not the same as x - 3. You have to keep the values given in order.
