Answer:
last one
Step-by-step explanation:
p=21 + 2w
p-21=2w
p-21/2=w
Total ratio = 2 + 3 + 5 = 10
Sum of angles in a quadrilateral is 360
4th angle = 130
360 - 130 = 230
Sum of remaining 3 angles must be equal to 230
1st angle 2/10 * 230 = 46
2nd angle 3/10 * 230 = 69
3rd angle 5/10 * 230 = 115
Adding all angles together 46 + 69 +115 + 130 = 360
This is a linear function. They vary directly with each other.
x increasing by 1 each time.
y increases by 4 each time.
I hope this helps!

The answer is $19,360 because we multiply the annual interest rate of 6% or .06 by 3.5 years and we get a total interest of .21. The answer is found by performing $16,000 times 1.21 and we get $19,360.
1). Add 9 to each side of the equation.
2). Multiply each side by 4 .
3). Divide each side by 3 .
4). Gaze wondrously upon the answer.
