The weight of Jacob’s backpack is made up of the weight of the contents of the backpack as well as the weight of the backpack itself. Seventy percent of the total weight is textbooks. His notebooks weigh a total of 4 pounds, and the backpack itself weighs 2 pounds. If the backpack contains only textbooks and notebooks, which equation can be used to determine t, the weight of the textbooks?

0.7(t) = t – 4 – 2
0.7(t) = t + 4 + 2
0.7t(4 + 2) = t
0.7(t + 4 + 2) = t

The equation that can be used to determine weight of the textbooks is [tex]0.7(t + 4 + 2) = t[/tex]

What is Weight?

Weight serves as the relative mass that can be found in a particular matter.

Let the weight of the textbooks= t

The backpack of the book= 2 pounds

The weight nootbook in total = 4 pounds

But remember that 70% of total weight is the textbooks.

Therefore the equation can be computed as

70%(t + 4 + 2) = t

[tex]70/100(t + 4 + 2) = t[/tex]

[tex]0.7(t + 4 + 2) = t[/tex]

Therefore, option D is correct.
