1. Calculate how many hours passed between her temperature checks. 8 p.m to 8 a.m. is 12 hours.
2. Calculate the total change in temperature. 36 - 54 is -18, so the temperature went down by 18 degrees.
3. We are looking for degrees per hour, so we put derees(18) over hours (12) to get 18/12.
4. Calculate by dividing. The answer is 1.5 degrees per hour.
Answer:
(f+g)(x)=5x-4
(f*g)(x)=(4x^2-19x-5)
(f-g)(3)=(-15)
Step-by-step explanation:
(f+g)(x)=(x-5)+(4x+1)=(5x-4)
(f*g)(x)=(x-5)(4x-1)=(4x^2-19x-5)
(f-g)(3)=(x-5)-(4x-1)=(3-5)-(4(3)+1)=(-2)-(12+1)=(-2)-(13)=-15 substitute 3 for x

Answer:
x=80
Step-by-step explanation:
The angle of a line is 180*.
The equation would be (x+20)+x=180
Subtract 20 from both sides: 2x=160
Divide by 2: x=80
That's your answer!
I hope this helps!
