Answer:
x=34
m∠S = 38
m∠T = 111
Step-by-step explanation:
Since the angles of a triangle should add up to 180, you can solve this equation:
31 + x+4 + 3x+9 = 180
the solution is x=34
Then the angles S and T can be found by substituting that value for x.

2 x B + 4 = -8
-4 -4
2 x B = -12
divide by 2 on both sides
B = -6
Athena purchased a chain for $5 and sold it for $ 15, her profit for each chain is $15-$5. So for 2 chains, her net profit = 2*(15-5)
She also purchased bracelets for $8 and sold them for $9, her profit for each chain is $9-$8 . So for three 3 bracelets, her net profit = 3*(9-8)
Net profit from chains = 2*(15-5) or 2*15 - 2*5 (distributive property)
Net profit from chains = 2*10 or 10*2 (Commutative property)
Net profit from chains= $20
Net profit from bracelets = 3*(9-8) or 3*9 -3*8 (distributive property)
Net profit from bracelets = 3*1 or 1*3 (Commutative property)
Net profit from bracelets = $3
