Write and solve an equation of ratios, as follows:
15 250
----- = ------- = 10/12.
x 300
Then 15(12) = 10x, and x = 18. The company could well predict that 18 out of the 300 phones it sells in July will be defective, based upon past history.

Step-by-step explanation:
A way to make your grades go higher is by asking your teacher for extra credits. If you fail some quizzes ask your teacher to re-take it to get a better grade, another way is ask your teacher for assistance on assignments.
Answer:
Since C is the mid point,
therefore, (6x - 4)/2 = 4x-3
=> 6x - 4 = 2X(4x-3) = 8x - 6
=> 6x - 8x = -6 + 4
=> -2x = -2
=> x = (-2)/(-2) = 1
Hence, CD = AC = 4x - 3 = 4X1 - 3 = 1
Step-by-step explanation:
Answer:
x = 13.5
BC = 30
Step-by-step explanation:
BC is double the length of DE. And we know that DE is equal to 15. So 15 x 2 is 30.
Now to find x. We know that our answer has to add up to 30. So we first subtract 3 from 30 to get 27. Then divide 27 by 2 to get what x is equal to. x = 13.5
