The <em><u>correct answer</u></em> is:
22.5°F.
Explanation:
The temperature rises 1.5°F each hour. From 5:00 AM to 12:00 PM is 12-5 = 7 hours. This gives us a rise of 7(1.5) = 10.5°.
An increase of 10.5° makes the new temperature 12+10.5 = 22.5°F.
Wait is their only three answer choices? I got 40 but I’m guessing the closest one would be 36.5.
10x+3y=43
-9x-y=-20
From second equation,
y=-9x+20
Substitute third equation into first equation,
10x+3(-9x+20)=43
10x-27x+60=43
-17x=43-60
-17x=-17
x=1
y= -9+20= 11
Option B
Multiply 0.26 by 520 to get 135.2 gallons
Answer: FALSE .
