X = number of cds on the rack
x + 7 = 30
x = 30 - 7
x = 23 <== so there are currently 23 cds on the rack
First you have to know how many inches are in a square cm and then the answer that you get for that first part you just multiply that by what you have but dont use a calcutor cause it wont give you the right answer because i had this before and i got it correct
<span>Owls are found in many different habitats, such as deserts, forests, prairies and even the Arctic tundra. They nest in trees, in holes in the ground, in barns, and in caves. And while many other birds migrate to warmer places during the winter, most owls do not. They live in the same place all year round.</span>
My guess would be -54 because we are starting with -54
