Answer:
Step-by-step explanation:
you add two angles and then subtract it from 180 degrees
Hopefully it is right
for example: A angle+B angle-180 degrees
Answer:
Step-by-step explanation:
Use the point-slope formula.
y - y_1 = m(x - x_1) when : x_1 = -5 and y_1 =3 and m= -6/5
the equation :
y - 3 = -6/5(x +5)
Answer: (C) 
Explanation:
The difference between the degrees in Fahrenheit and the constant 32 corresponds to the expression in brackets (F-32). The fraction 5/9 of that difference completes the expression: (5/9)(F-32) and gives the degrees Celsius.
Answer:42 degrees
Step-by-step explanation:
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.
