If the air temperature is $-14^{\circ} F$, how many degrees must it rise to reach $0^{\circ} F$?
A. $14^{\circ} F$
B. The answer depends on other factors not given in the problem.
C. $15^{\circ} F$
D. $-14^{\circ} F
Answer (1)
We start with an air temperature of − 1 4 ∘ F .
We want to find the temperature increase needed to reach 0 ∘ F .
We set up the equation − 14 + x = 0 , where x is the temperature increase.
Solving for x , we find that x = 14 , so the temperature must rise by 1 4 ∘ F .
Explanation
Understanding the Problem We are given that the current air temperature is − 1 4 ∘ F and we want to find out how many degrees it must rise to reach 0 ∘ F .
Setting up the Equation Let x be the number of degrees the temperature must rise. We can set up the equation: − 14 + x = 0
Solving for x To solve for x , we add 14 to both sides of the equation: x = 14 Therefore, the temperature must rise by 1 4 ∘ F to reach 0 ∘ F .
Final Answer The air temperature must rise by 1 4 ∘ F to reach 0 ∘ F .
Examples
Imagine you are a chef and you need to cool down a soup from − 1 4 ∘ F to 0 ∘ F for optimal serving temperature. Knowing how many degrees the temperature needs to rise helps you determine the amount of time or cooling adjustments needed to achieve the desired temperature. This simple calculation ensures the soup is served at the perfect temperature, enhancing the dining experience.
