The height, h, of a plant (in inches) w weeks since it was planted is represented by the equation h=1.2w+3. how many weeks will it take the plant to reach one foot?

7.5 weeks

Step-by-step explanation:

If you want to find out how long it take for the plant to reach a foot you set up the equation like so:

12=1.2w+3

and solve from there.

12=1.2w+3                       Subrtact 3 from both sides

9=1.2w                             Divide by 1.2 to isolate w

7.5=w                              Answer is 7.5 weeks

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%
