Jenny's algebraic expression:
y = 33d
where y is the total number of posts
total tweets in 5 days
y = (33)(5)
y = 165 tweets
Antonio's expression:
y = 5d
total tweets in 5 days
y = (5)(5)
y = 25 tweets
Altogether they have posted:
165 + 25 tweets = 190 tweets in five days
Answer:

m² = 27/3
m² = 9
m = √9 = √3*3
m = 3
