Answer:
25 Minutes
Step-by-step explanation:
Well, 1/4 of an hour is obviously 15 minutes. So if she read 3/5 of the book in 15 minutes, you have to find how long it took her to read 1/5 of the book. If 15 minutes is 3/5, then 15/3 is 5, which is the time it took to read 1/5 of the book. You add 10 to 15 and you get 25. I hope this helps!
Answer:
Length of AB = 4.4721
Equation of line BC: y = -2x + 6
Step-by-step explanation:
To find the length of the line AB, we just need to find the distance between the points A and B.
We can find distance with the equation:



To find the equation of the line BC, first let's find the slope of the line AB.
This slope is given by:


The line AB is perpendicular to the line BC (because mB = 90°), so the slope of line BC is:

so the line BC is:

To find the value of b, we can use the point B (1,4):


So we have:

Answer:
x = 3
Step-by-step explanation:
Here, we want to find the value of x
By mathematical convention;
NM = NL + LM
Now, substitute individual values
3x + 13 = (6x-5) + (2x + 3)
3x + 13 = 6x-5 + 2x + 3
3x + 13 = 8x -2
Collect like terms
8x -3x = 13 + 2
5x = 15
x = 15/5
x = 3
6. 150 degrees
7. 70 degrees
8. 100 degrees
