When Jonell checked the temperature in the morning, he saw that it was -4F. Late that afternoon, the temperature was 15F. Select the equation that represents this situation.
-4+x=15;x=The number of degrees the temperature rose
-4+x=15;x=The current temperature
x=15-4;x=The number of degrees the temperature rose
x=15-4;x=The current temperature
I choice B
Yes, B.
The correct choice is actually A: -4+x=15;x=The number of degrees the temperature rose.
In this equation, x represents the number of degrees the temperature rose. By subtracting the initial temperature (-4F) from the final temperature (15F), we can determine how much it increased.
To represent the situation described, where the temperature in the morning was -4F and later in the afternoon it rose to 15F, you would use the equation:
x = 15 - (-4)
The correct equation would be x = 15 - 4.
This equation represents the difference between the afternoon temperature (15F) and the morning temperature (-4F), which gives you the number of degrees the temperature rose.
