Divide by -4 on both sides.
11=x
The circumference of the circle is equal to
C = 2πr, where r is the radius of the circle.
Substituting r = 1, the circumference is equal to
C = 2π
Since the arc ab is π/3, its fraction of the circumference is equal to
Fraction = π/3 ÷ 2π
Fraction = 1/6

Answer:
He invested approximately $2,215
Step-by-step explanation:
Mr Y invested $2000 in two accounts.
One pays 7%, and the other pays 5%.
At the end of one year, Mr Y earned $155 in interest. We want to know how much Mr Y invested in the account paying 7%.
Let the amount he invested be X, then
7% of X = 155
(7/100)X = 155
0.07X = 155
X = 155/0.07
= 2,215
He invested approximately $2,215
