A importância de 588 foi dividida entre 3 pessoas. Sabendo que a parte da primeira está para a parte da segunda como 5 para 7, e que a parte da segunda está para a parte da terceira como 7 para 9, determine as 3 partes

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

r and t.

both are 64 degrees.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
