A hand-held digital music player was marked down by 1/4 of the original price.

1 answer:

3 0

It was marked down 1/4 of the original price to $128. That means $128 is equal to 3/4 of the original price. So the original price would be 4/3 of $128. I get $170.67 (rounded to the nearest cent).

6(4+7k)=-3k-6(4+k) k=?

Alona [7]

Answer:

-16/15

Step-by-step explanation:

ok let's break this down.

6(4+7k) = 6*4 + 42k (use distributive property)

3k - 6(4+k) = 3k - 24 - 6k (do the same thing)

24 + 42k = 3k - 24 -6k (let's simplify this a bit)

24+42k = -24-3k (add 3k on both sides)

24+45k=-24 (subtract 24 on both sides)

45k = -48

k = -48/45 or -16/15
