Answer:
C
Step-by-step explanation:
Hose A:
60 gallons every 15 minutes mean:
60 / 15 = 4 gallons per minute
For Hose B:
If we put x = 1, we can find gallons (y) per minute (x)
y = 3 x
y = 3(1)
y = 3
That means 3 gallons per minute
Thus, the rate of Hose A is 1 gallon per minute more than the rate of Hose B. Option C is correct.
The absolute value of a real number is a positive value of the number. Which means that the absolute value is the distance from zero of the number line. However, that of the complex numbers is the distance from the origin to the point in a complex plane.
Answer:
x=1
Step-by-step explanation:
20(3x-3/5) = 20(2x-2/4)
12x-12= 10x-10
12x-10x =12-10
x= 1
