Answer:
Unit rate of change = -4.2°F/hour
Step-by-step explanation:
Assuming a constant rate of change, a relationship between the change of temperature as a function of time (in hours) can be described as follows:

There is a temperature drop from 12pm to 5pm, which explains the rate of change being negative. This rate means that at every hour that goes by, the temperature drops by 4.2 degrees.
Answer:
Let bags of pecans cost = x
Make an equation :
Bags of almonds cost = x + 3 (they said almonds cost 3 dollars more)
Total number of bags ordered: (3 bags pecans) + (5 bags of almonds)
Cost for pecans = 3x
Cost for almonds = 5(x + 3) = 5x + 15
Price of pecans + price of almonds = total cost
Solve for x:
3x + 5(x + 3) = 55 (remove brackets)
3x + 5x + 15 = 55 (add like terms)
8x + 15 = 55
8x + 15 - 15 = 55 - 15 (get rid of the 15)
8x = 40
8x/8 = 40/8
x = 5
bags pecans cost is $5
bags of almonds is $5+$3 = $8
Answer:
The two numbers are 2928 and 1878
Step-by-step explanation:
Given this information, we can set up two equations:
x + y = 4806
x - y = 1050
We can solve these simultaneous equations by elimination, which means we can either add or subtract the two equations to solve one of the variables.
In this case, adding the equations together will eliminate y so we can solve for x (remember that y + - y is the same as y - y):
x + y = 4806
+ x - y = 1050
____________
2x = 5856
This can then be simplified to x = 2928 (by dividing by 2)
Now we know x, we can substitute this value into any equation to find y:
2928 + y = 4806 so y = 4806 - 2928 which is 1878.
The two numbers are 2928 and 1878.
