Marty has saved $72. He spent $8 on a video rental. Write a ratio as a fraction in simplest form to represent what portion of his savings he has left.
a)64/72
b)8/72
c)1/9
d)8/9

D) 8/9

Step-by-step explanation:

You subtract 8 from 72 to get 64 which is the amount he had left so it would equal 64/72 but it asks for simplest form so you find the greatest common denominator which is 8 to get 8/9

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.

lol.

it's ok we all do this sometimes.
