An underground spring fills a small pond in 12 days. Evaporation from the surface of the pond can empty it in 28 days. If the pond is completely dry, how long will it take to fill again

12 days

Step-by-step explanation:

It takes 12 days for an underground spring to fill a small pond

It takes 28 days for the pond to be empty through evaporation

If the pond is completely dry, how long will it take to fill again?

It will take 12 days for the underground spring to fill the pond again

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

just needed some points but try socratic
