Since you that that line is 180 degrees you can simply do 180-149 and find that the answer is 31 degrees. So you would do 13x+5=31, 31-5=26, 26/13, and then x=2 :)
Answer:
One group forms through the chemical precipitation and crystallization of elements and compounds from solution. Elements such as calcium, sodium, potassium, and magnesium are commonly released into the environment through a variety of chemical weathering processes. These elements can then become dissolved into aqueous solutions that are often transported via runoff, stream flow, or groundwater flow. If this solution enters a basin environment where evaporation exceeds precipitation and in-flow, sedimentary evaporites can form because of the loss of water from the solution.
The oceans are almost saturated with dissolved calcium carbonate. This compound originates from the shells of a variety of marine organisms that use it for the construction of shells and other hard body parts. Because these organisms are surrounded in a solution, some of the calcium carbonate dissolves into the ocean waters. Under the right circumstances the dissolved calcium carbonate can precipitate out forming chemically created limestone deposits. The formation of dolomite involves the chemical modification of limestone deposits by a magnesium rich solution.

150/28=6.5.... so you would put 7 because you can't use 6.5.... shelfs.
Answer:
13.5
Step-by-step explanation:
7.5 percent *180=
(7.5:100)*180=
(7.5*180):100=
1350:100= 13.5
He lost 8, so he is at -8, he then gains 15 so add 15 to -8"-8 + 15 = 7
He gains 7 so now add 7 to the total: 7+ 7 = 14
He then loses 4, so now subtract 4 from the total: 14 - 4 = 10
Answer: He gained 10 yards.
