I need help with 9 and 10

#9) 180 - 116 = 64

(3x -13) + ( 2x +4 ) + 64 = 180

5x - 9 + 64 = 180

5x = 180 + 9 - 64

5x = 125

x = 25

#10) 3x - 13

= (3× 25) - 13 = 62

m< A = 62°

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.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
