Answer:
MB = 21
Step-by-step explanation:
If M is the midpoint of AB, then AM = MB
AM + MB = AB
AM + AM = AB
Replace with AM = 3x+3 and AB = 8x-6
3x+3 + 3x+3 = 8x-6
Combine like terms
6x +6 = 8x-6
Subtract 6x from each side
6x-6x +6 = 8x-6x-6
6 = 2x-6
Add 6 to each side
6+6 = 2x-6+6
12 = 2x
Divide by 2
12/2 = 2x/2
6 =x
Now we want to find MB = AM
MB = AM
MB = 3x+3
= 3(6) +3
= 18+3
=21
Answer : The correct option is (A) 68.
Step-by-step explanation :
As we are given that:
LN = 6x - 5
LM = x + 7
MN = 3x + 20
Now we have to determine the value of MN.
According to the question:
LN = LM + MN
Now putting all the given values in this expression, we get:
6x - 5 = (x + 7) + (3x + 20)
6x - 5 = 4x + 27
6x - 4x = 27 + 5
2x = 32
x = 16
The value of MN = 3x + 20 = 3(16) + 20 = 48 + 20 = 68
Therefore, the value of MN is 68.
Not completely sure how to answer your question but all 20 questions where worth 5 points each which she would have gotten a 100 if she got all right but she got 15 which her score would be 75. I think in a ratio of correct to incorrect would be 75:100 , I'm not sure completely.
