Answer:

read the question and you will find the like the question and just find it out The weather report says the temperature is 20°c and will drop 5°c per hour for the next 6 hours.

Temperature drops by 5°c per hour

So we find the temperature after 6 hours

In 1 hour temperature drops= 5°c

So in 6 hours = 6* 5 = 30°c

In 6 hours , temperature drops by 30°c

the actual temperature is 20°c. after 6 hours the temperature becomes

20°c - 30°c= -10°c

So, after 6 hours the temperature will be -10°c

Daryl plans to be gone for at least 6 hours. so its 6 hours or more than 6 hours

In 6 hours or more than 6 hours , the temperature will drop less than  -10°c

IrinaK [193]

Answer:

Uranus : 15

Saturn : 18

Step-by-step explanation:

Uranus = U

Saturn = S

1) U= S -  3

2) U+ S = 33

1)* U - S = -3

2)* U + S = 33

1)* + 2)*      2U = 30, so U = 15

Then Saturn will have 18 (because they add up to 33)
