The equation Y= 1.9X can be used to determine the total weight in pounds, y, of the number of paperback books in the first printing of Zamir's novel, x. The equation was used to fill in the table below. Weight of Books Total Weight (in pounds) 1 90 Number of Books 100 150 200 250 380 4 What value is missing from the table?

i am positive it is 280

Step-by-step explanation:

because if you subtract 475 from 380 you get 90

and then you can add 90 to 190 to get the unknown number

hopefully this helped :)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
