2. Two numbers are in the ratio of 3 : 5. If 8 is added

Mathematics
1 answer:
Vesnalui [34]3 years ago
3 0

Answer:

 x/y = 3/5

=> x = (3/5)y   (1)

(x + 8)/(y + 8) = 2/3

=> 3*(x + 8) = 2*(y + 8)

=> 3x + 24 = 2y + 16

=> 3x - 2y = -8   (2)

From (1) and (2), we have:

=> 3*(3/5)y - 2y = -8

=> (-1/5)y = -8

=> y = 40

=> x = (3/5)*y = (3/5)*40 = 24

=> Solution: x = 24, y = 40

Hope this helps!

Answer:

3,406.5 litres/hr

Step-by-step explanation:

The liquid is being poured at a rate of 15 gallons per minute.

1 minute = 1/60 hour

Thus, the rate can be written as:

15 gallons pet 1/60 hour

We are told that one gallon is approximately 3.785 liters.

Thus;

15 gallons = 15 × 3.785 litres = 56.775 litres.

Thus, the rate is;

56.775 litres per 1/60 hour

We want to find in litres/hr.

By proportion, we have it as;

(56.775 ÷ 1/60)/1 = 56.775 × 60 = 3,406.5 litres/hr
