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

side 5 times 5 = side 25 on the left triangle
side 6 times 5 = side 30 on the left triangle
so...
side 8 time 5 = side 40 on the left triangle which is the answer
