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

Step-by-step explanation:

Given: 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.

Let t be the weight of textbooks, then the total weight in the bag will be

Since,  Seventy percent of the total weight is textbooks.

Also, 70%=0.7

According to the question,

a is the right answer

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
