The equation that shows how many students are absent is 26 + a = 30
Selecting the equation that shows how many students are absent
From the question, we have the following parameters that can be used in our computation:
Total = 30
Present = 26
Using the above as a guide, we have the following:
Present + Absent = Total
Substitute the known values into the equation
26 + Absent = 30
Let a = Absent
So, we have
26 + a = 30
Hence, the equation is 26 + a = 30
Question
there are 30 students in class. today 26 students are present.choose an equation to show how many students are absent
26 + 30 = a
a - 26 = 30
26 + a = 30
26 - a = 30
