the weight of jacobs 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

Answer

Explanation:

Step1: Find the total weight of the backpack

The total weight of the backpack is the sum of the weight of textbooks (t), notebooks (4) pounds, and the backpack itself (2) pounds. So the total weight is (t + 4+2).

Step2: Use the percentage of textbooks' weight

Since textbooks account for (70%) (or (0.7)) of the total weight, we can write the equation as (0.7\times(\text{total weight})=\text{weight of textbooks}). Substituting the total weight from Step1, we get (0.7(t + 4+2)=t).

Answer:

(0.7(t + 4+2)=t) (the fourth option)
