Answer:
A closed dot represents a lreater than or equal to or less than or equal to, which can be distinguished in an inequaity's equation by an underline.
Step-by-step explanation:
Answer: Figure 2.
Step-by-step explanation:
Suppose that we have an angle with measure ∠M, a bisector would be a line that divides this angle in two equal parts, such that each new angle has measures (∠M)/2
Then the correct option will be the one that has two equal angles.
In figure 2, we can see that RP divides the angle SRQ in two angles 52°, then RP is the bisector of the angle.
Then the correct option is figure 2.
Let the slower train's velocity be x-21
Let the faster train's velocity be x
We know that the approach speed is the sum of both speeds, so x+x -21= 2x-21.
The approach rate is given by Distance/time = 471/3 = 157mpH
x+x-21=157
2x=157+21
2x=178
x=89mph
The slower train is travelling 89-21 = 68mph
The faster train is travelling 89mph.
Answer:
It's 3/2p!
Step-by-step explanation:
Because Helen do the same number of exercises on 2 days, the time to do and the average rate are inversely proportional!
So, if on Monday, Helen's average rate is p then on the next day, her average rate is:
p × 3 ÷ 2 = 
=3/2p

45+90+x=180
135+x=180
x=180-135
x=45
