Aa batteries come in  packs of 4. last month, joe used 58 batteries in his remote control drone. how many  packs  of batteries did he have to open?  

Batteries come in a pack of 4.

This means

Number of batteries in each pack = 4.

Number of batteries Joe used last month for his remote controlled drone  = 58.

Number of packets he needs to open = 58/4 = 14.5

But you cannot open half a packet.

So the number of packets we need to open to use 58 batteries is 15.

what does muffins have to do with anything?

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
