we know that
total of sum of arc is 360
so, sum of both arc must be 360
so, we get
now, we can solve for x
............Answer
If point A is between B and C, then CA+AB = CB by the segment addition postulate. This is the idea of taking two smaller segments to "glue" them together to form a larger segment. Or you can think in reverse: take some larger segment and split it somewhere in between the endpoints (not necessarily the halfway point), this will produce two smaller segments.
For example: you have a ruler that is 12 inches. Take a saw and cut the ruler at the "2 inch" marker. You'll end up with two smaller pieces of plastic: one of which is 2 inches, the other 10 inches. The two smaller pieces can be taped together to reform the original 12 inch ruler.
We can write the following proportion between the milligram and milliliters:
Solving for x, we have
Intuitively, the original 1000mg/250ml solution tells us that the number of milliliters is one fourth of the number of milligrams.
So, if we want 700mg, we have one fourth of this value for the milliliters:
Answer:
Step-by-step explanation:
Use distributive property: a*(b +c) =a*b + a*c
-3( 6 - 1.5n) = (-3)*6 - (-3)*1.5n
= -18 + 4.5n
