A company produces fruity drinks that contain a percentage of real fruit juice drink a contains 20% real fruit juice and drink b contains 5% real fruit juice the company used 56.5 L of real fruit juice to make 80 more liters of drink b than liters of drink a. write a system of equations that could be used to determine the number of liters of drink a made and the number of liters of drink b made. Define the variables that you use to write the system

angle addition postulate

2x=56

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

the answer is d

for problems like this theres an app, its photomath that explains the problem and gives the answer hope i
