Answer:
6
Step-by-step explanation:
Given:
The figures of triangles and their mid segments.
To find:
The values of n.
Solution:
Mid-segment theorem: According to this theorem, mid segment of the triangle is a line segment that bisect the two sides of the triangle and parallel to third side, The measure of mid-segment is half of the parallel side.
9.
It is given that:
Length of mid-segment = 54
Length of parallel side = 3n
By using mid-segment theorem for the given triangle, we get



Divide both side by 3.


Hence, the value of n is equal to 36.
10.
It is given that:
Length of mid-segment = 4n+5
Length of parallel side = 74
By using mid-segment theorem for the given triangle, we get




Divide both side by 4.


Hence, the value of n is equal to 8.
Answer: 
r=26
Step-by-step explanation:
Given: Mrs. Morton rewards her students on behave well by putting 3 marbles into a marble jar.
If the jar contains 24 marbles. and r represent the number of additional times the class is rewarded then the required equation will be

If we solve it, we will get the minimum the jar contains 24 marbles.
To solve equation, subtract 24 from both sides, we get

Hence, the minimum whole number of additional times they need to be rewarded so they can have a party=26
