Jimmy is going to pack his backpack for a trip. his backpack is 60 cubic litres. he has a pile of equipment that takes up 43 cubic litres and then he has his sleeping bag that takes up 23 cubic litres. let r be the amount of room left in his backpack. which equation could you use to determine if he has enough room in his backpack.

r = R - ( 43 + 23 )

There is no more space in his backpack.

Step-by-step explanation:

Jimmy's backpack has a space of 60 cubic liters (R).

Now, he has a pile of equipment of volume 43 cubic liters and then he has his sleeping bag of volume 23 cubic liters.

Now, if r is the amount of room left in his backpack, the equation I can use

r = R - ( 43 + 23 ) (1) to determine if he has enough room in his backpack.

Now, in our case R = 60 cubic liters

Therefore, from equation (1), we get r = 60 - ( 43 + 23 ) = - 6, i.e. there is no more space in his backpack. (Answer)
