x+y=120_______1
x=4*y_________2
x=4y
substitute 4y for x in equation 1
`4y+y=120
5y=120
eliminate the coefficient of y
y=120/5
y=24
now,input 24 for y in equation 2
`x=4y
x=4*24
x=96
thus, the numbers are
96 and 24
Answer:
B) 
Step-by-step explanation:
You distribute:

A ratio shows us the number of times a number contains another number. The amount barely needed for 300 ml of milk is 45 grams.
<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
The need for barley in 200 ml of milk is 30 grams, therefore, the need for barley in 1 ml of milk can be written as,
Need of barely in 1 ml of milk = 30/200
Now, the amount of barely that will be needed for 300 ml of milk will be,
The amount of barely in 300 ml of milk = (30/200)×300 = 45 grams.
Hence, the amount barely needed for 300 ml of milk is 45 grams.
