Answer:

180

Step-by-step explanation:

total ratio is 15

gallons of red =

\frac{12}{15}  \times 6 \times  \frac{15}{0.5 }  \\  \\  = 144

gallons of yellow

30

gallons of blue

\frac{0.5}{15}  \times 30 \times  \frac{15}{2.5}  \\  \\  = 6

total =144+30+6

=180

The sum of two numbers is twice their difference. the larger number is 6 more than twice the smaller. find the numbers.
soldi70 [24.7K]
Let the numbers be x and y; x being the larger number and y being the smaller.

Given,
 
x + y = 2* (x - y)

x + y = 2x - 2y

x = 3y

Also given,

x = 6 + 2y

3y = 6 + 2y

--- y = 6

Thus, x = 3y = 3*6 = 18.

Therefore, the numbers are 18 and 6.
