Answer:
The third side is 17m-4
Step-by-step explanation:
The perimeter of a triangle is the sum of the three sides. Call the third side x
x + 5m-7 + 2m+5 = 24m -6
Combine like terms
x +7m-2 = 24m -6
Solve for x
Subtract 7m from each side
x +7m-7m -2 = 24m-7m -6
x -2 = 17m-6
Add 2 to each side
x-2+2 = 17m-6+2
x = 17m-4
The third side is 17m-4
Answer:
3/8 of the day
Step-by-step explanation:
A day is 24 hours
You spend 9 of them sleeping
The fraction you spend sleeping is
9/24
You can simplify the fraction by dividing the top and bottom by 3
9/3 = 3
24/3 = 8
3/8

Answer:
NM = 15
Step-by-step explanation:
There is a property of secants and tangents to a circle where:
The square of the tangent length is equal the length of the external segment of the secant times the whole secant length.
Therefore, in our question, we have that:
The values of NM, ML and MK are:
So we have:
So the length of NM is:
1.25 - 0.5 = 0.75
1.25 hours = 1 hour 15 minutes
0.5 hours = 30 minutes
1 hour 15 minutes - 30 minutes = 45 minutes
