Step-by-step explanation:
Tan (53) = tree height / 9 m
tree height = tan (53) * 9

Answer:
5b = 20
Step-by-step explanation:
Since Abdul bought b books and Debra bought 5 times as many books as Abdul, then 5b represents the number of books Debra bought. Since we know that Debra bought 20 books, we can write an equation to represent that: 5b = 20.
(Abdul bought 4 books in that case)
Answer:
0.15*t < 5.00
33 texts
Step-by-step explanation:
given : $0.15 per text; unlimited cost is $5.00
# of texts = t
0.15*t < 5.00
t < 33.33; since you cannot make 33.33 texts i will round down to 33 texts.
Basically you can send or receive up to 33 texts and it will be cheaper than $5.00
0.15(33) = $4.95
at 34 texts, 0.15(34) = $5.10
