The equation can be used to determine t, the weight of the textbooks is t = 0.7w
Given:
let
Total weight = w
Weight of notebook = n
Weight of backpack = b
Weight of textbook = t
w = n + b + t
where
n = 4 pounds
b = 2 pounds
t = 0.7w
So
w = 4 + 2 + 0.7w
w - 0.7w = 4 + 2
0.3w = 6
w = 6/0.3
w = 20
Recall,
t = 0.7w
= 0.7(20)
= 14 pounds
Therefore, the weight of the textbook is 14 pounds

Answer:
x = -5, x = -6
Step-by-step explanation:
After canceling common terms from numerator and denominator, there are two factors remaining in the denominator that can become zero. The vertical asymptotes are at those values of x.
The denominator will be zero when ...
x + 5 = 0 . . . . at x = -5
x + 6 = 0 . . . . at x = -6

Answer: The cost of 5.5 pounds strawberries =$ 7.98
Step-by-step explanation:
Given: A local grocery story has strawberries on sale for $1.45 per pound.
i.e. Cost for 1 pound strawberries = $1.45
Now, Cost of 5.5 pounds strawberries = 5.5 x (Cost for 1 pound strawberries)
= $ (5.5 x 1.45)
= $ 7.975 ≈ $ 7.98 [ Round to the nearest penny]
Hence, the cost of 5.5 pounds strawberries =$ 7.98
