in the morning , Emily studied 40 minutes for an exam. Later that evening, Emily studied for x more minutes. write an equation that represents the total number of minutes, y, Emily studied for the exam
Step-by-step explanation: y is the total number of minutes Emily studied for the exam. we already know that she studied for at least 40 minutes. But we also know that y does not equal 40. with the additional amount of time, x minutes, we can discern that y = 40 minutes plus the additional x minutes, which is simply y = 40 + x.
