Supplementary angles are angles that are adjacent to each other and when summed to get a total of 180 degrees. In this case, DEF and FEG are supplementary. Thus the equation is <span>9x +1 + 8x + 9 = 180 = 17 x + 10; x then is equal to 10 so
<</span>DEF = <span>9*10 +1 =91 degrees
</span><FEG = <span>8*10 + 9 = 89 degrees</span>
C. 1.5%, 0.125, 3/20, 1 4/5 is the correct answer
Answer:
Starbucks by 1 cent difference.
Step-by-step explanation:
Divide: 3.36 divided by 24 to find Starbucks. You get 14 cents per ounce
Divide: 2.40 divided by 16 to find Circle K. You get 15 cents per ounce
Compare: Starbucks is cheaper by 1 cent.
A = amount
.01a + .05a + .1a = 1.28
Combine like terms.
.16a = 1.28
Divide both sides by .16.
a = 8
8 * 3 = 24
There are 24 coins in the wallet.
