From midnight to 4:00 am, the temperature dropped 1.75°C each hour. If the temperature at 4:00 am was -16°C, what was the temper
ANTONII [103]

Answer: -11 degrees Celsius

Step-by-step explanation:

4:00 am = -16 degrees

You know that 4:00am is four hours after midnight and you know that the temperature decreases by 1.75 degrees every hour so during that time it has dropped by:

1.75x4=7 degrees

Because it is -16 at 4:00am, you know it was 7 degrees higher at midnight

-16+7=-11

It was -11 degrees at midnight

A stadium has two sections, A and B.
Alekssandra [29.7K]
ANSWER: a=12 b=15
Explanation: (look at work below)

4a + 1b = 63 (eq1)
5a + 3b = 105 (eq2)
-12a + -3b = -189 (subt. eq1 from eq2)
————————-
-7a = -84
a = 12
4(12) + 1b = 63 (plug in the a value)
48 + 1b = 63
b = 15
