Answer:
D. 66 degrees Fahrenheit
Step-by-step explanation:
6 hours after 6 p.m. the temperature will have dropped 6×4 °F = 24 °F. When it drops that amount from 90 °F, it will be ...
90 °F -24 °F = 66 °F . . . . temperature at midnight
Answer:
Multiply the first equation by 3
Multiply the second equation by -7
Step-by-step explanation:
After doing the above method, you will derive equation 3 and 4 then you can eliminate the x and get y .

Is the question complete??
Answer:
A. y = 2x - 3
Explaination:
It can't be negative because then the slope would be going downward from left to right, this line is going upwards. Also, the steepness of the slope proves it is a slope of 2 because a slope of 1/2 isn't very steep. You can also count 1 unit over and look how much the line changes to find the slope.
I believe the answer is 60
1200 divided by 20=60
