Answer: 47.4 liters
Step-by-step explanation:
From the question, we are informed that Samuel's car usually takes about 12.5 gallons of gas to fill it up when it's empty and while in Canada, he noticed that one liter is equivalent to 0.264 gallons.
The number of liters it'll take to fill Samuels car will be:
= 12.5/0.264
= 47.4 litres
X = 7
y = 10
x + y = 700
7x + 10y = 6400
10x + 10y = 7000
(-) 7x + 10y = 6400
______________
3x = 600
x = 200
200 + y = 700
y = 500
Answer:y=12 x=00
Step-by-step explanation:
you can not
Y = 20x
y • x = 180
180/x = y
180/x = 20x
180 = 20x^2
x^2 = 6
x = + or - 3
Therefore y must equal + or - 60.
