Can someone me with my math homework, numbers 6,8, and 9? : )

Step-by-step explanation:

8) Take the cost that amelio spent-287.50 and multiply it by 0.15

287.50x0.15%=43.125.

Then, to figure out the cost he paid last year, subtract the 43.125 to ur original cost.

287.50-43.125=$244.375

9) 76.49x0.15%=11.4735

76.49+11.4735=87.9635

Hope this helps!

step-by-step explanation:

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
