Answer:

20 hours

Step-by-step explanation:

Make the denominators equal for the 2 fractions by multiplying 3 by 10 to make 30.  Do the same to the denominator, the answer being 20.  So, the 2 fractions will now be 1/30 and 20/30.  1 fits into 20, 20 times.

Please help due tmrw
Wewaii [24]

Answer:

1. w = 3l

2. k = 1/2 * b

Step-by-step explanation:

1.  w = 3l

   w = width     l = length

   Since we are solving the equation for the width, we can make the equation w = ? for now. since the width is equal to three times the length, we can make the equation w = 3l.

2. k = 1/2 * b

   k = kool-aid     b = beef    

   Since we are solving the equation for the kool-aid, we can make the equation k = ? for now. since the kool-aid is equal to half the beef sold, we can make the equation k = 1/2 * b

I hope this helped and please mark me as brainliest!
