Answer:
Step-by-step explanation:
=18÷[7+2{7+2(7-6)}+2]
=18÷[7+2{7+2×1}+2]
=18÷[7+2×9+2]
=18÷[7+18+2]
=18÷27
=
=9 two is 18 and 9 three is 27
So,
=
We need to find the principal amount on an interest rate of 13% where the end of year payment is $5043.71.
The original amount is .
i = Interest rate = 13%
n = Compounding period = 4 years
E = End of year payment = $5043.71
The required formula is
The original principal amount was .

Answer:
D) 132
Step-by-step explanation:
y + 3x = 180 {Co interior angles}
y = 180 - 3x ------------(I)
7x + 20 = y {Vertically opposite angles}
7x + 20 = 180 - 3x {From equation (I)}
7x + 3x +20 = 180
10x + 20 = 180
10x = 180 -20
10x = 160
x = 160/10
x = 16
Plug in x = 16 in equation (I)
y = 180 - 3x
= 180 - 3*16
= 180 - 48
y = 132
