I believe this is a rotation through an angle of +90°, anticlockwise, (counterclockwise), with the center of rotation origin(0,0)
To describe rotation we give the center of rotation and the rotation angle in degrees stating whether it is clockwise or counterclockwise.

Step-by-step explanation:
Answer:
x = 3t/b
Step-by-step explanation:
Step 1: Multiply both sides by 3
t = bx/3
3t = bx
Step 2: Divide both sides by <em>b</em>
3t/b = x
Let P = the PV (principal value).
n = 12, the monthly compounding interval
r = 2 = 0.02, the rate
nt = 20 months
The value if $20,000 after 20 months, therefore
P(1 + r/n)²⁰ = 20000
1.0339P = 20000
P = $19,344.86
Answer: PV = $19,344.86
325 adult tickets were sold
<em><u>Solution:</u></em>
Let "a" be the number of adult tickets sold
Let "s" be the number of student tickets sold
<em><u>Given that total 706 tickets were sold for the school play</u></em>
Therefore,
number of adult tickets sold + number of student tickets sold = 706
a + s = 706 --------- eqn 1
<em><u>There were 56 more student tickets sold than adult tickets</u></em>
Number of student tickets sold = 56 + number of adult tickets sold
s = 56 + a ------- eqn 2
<em><u>Let us solve eqn 1 and eqn 2</u></em>
<em><u>Substitute eqn 2 in eqn 1</u></em>
a + 56 + a = 706
2a + 56 = 706
2a = 706 - 56
2a = 650
a = 325
Thus 325 adult tickets were sold
