Answer:

Together they can wash  139 windows  in 12 hours

Step-by-step explanation:

t= windows they can  wash together

25/4 +32/6 = t/12

Find common denominator

150/24  + 128/24 = t/12

278/24=t/12

Cross multiplication:

24t = 3,336

Divide both sides by 24

t=139

12 POINTS PLEASE HELP
Elina [12.6K]

Answer: Supplementary angles have a sum of 180 degrees so you would subtract 79 from 180 to determine the value of its supplement which would be 101 degrees

While complementary angles have a sum of 80 degrees. So you would subtract 59 from 80 and that leaves you with 21, so the complement angle is equal to 21 degrees
