F (x) = 5x-10 determine x when f (x) = 15

5=x

Step-by-step explanation:

Ok, so if F(x)=15, then the equation would look like this:

The next step would be to add the 10 over from the right to the left side to get

Now divide both sides by 5 to get the answer.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

answer: 12   they all have at least 28 days
