Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

Answer:
448/32=14
Step-by-step explanation:
Answer:
4 5/12
Step-by-step explanation:
We need a common denominator of 12
4 3/4 = 4 3/4 *3/3 = 4 9/12
1/3 *4/4 =4/12
4 9/12 - 4/12 =4 5/12
7.) 4 (-2) 12 I multiply 4 by -2 which gives me
-8 = 12 so it is a no solution
8.) 39 - 3 = -6 (4-3)
first u want to multiply the -6 by four and the -6 by the -3 which gives you :
39 - 3 = -24 + 18
36 = -6
this is also a no solution
