There are 2 germs in a jar and they multiply by 2 every minute how many germs are there after a hour

240

Step-by-step explanation:

1.) 60 times 2

   There are 60 minutes in a hour and since there are 2 germs in the jar.

2.) 120 times 2

   120 from the total, and 2 germs are made every minute, you multiply.

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.
