Final answer:
The value of the expression is 31.
Step-by-step explanation:
Substitution is a process of putting the values of variable in the expression.
Given: p=17 and q=3
To find: value of 2p-q
We will substitute the values and simplify.
Putting the values of variables in the expression as
2p-q = 2x17-3 =34-3 = 31

Answer:
The integer that represents the change in the temperature each week = 5
The temperature of the weather drops 5°F each week
Step-by-step explanation:
The given parameters regarding the weather are;
The range over which the temperature dropped = 20°F
The duration over which the temperature dropped = 4 weeks
The rate at which the weather dropped each week = The same amount (constant rate)
Therefore, we have;
For a constant rate of change, the rate of change of the temperature of the weather, m, is given as follows;
m = (The change in the temperature)/(The duration of the change)
m = 20°F/(4 weeks) = 5°F/week
The integer that represents the change in the temperature each week = 5
C is the answer have a great day
