Fred Flintstone bought seven boxes to put with his collection of boxes. A week later half the
boxes were ruined in the rain. There are now only 22 boxes left. With how many did he start?
What equation can I use to solve this?

He started with 37.

Step-by-step explanation:

I reasoned

There are 22 left ( a result of being halved ) which means there must have been 44 just before that.  And, he added 7 boxes to get that 44 total. So, what is 7 less than 44?

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^

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
