Answer: Option D. 16
Solution:
If LM is a midsegment of IJK, it is joining the midpoint of the sides IJ and IK, and it's half the length of the base of the triangle (JK), then:
L is the midpoint of the side IJ, and divides it into two congruent parts:
IL=LJ
Replacing IL by 7x and LJ by 3x+4:
7x=3x+4
Solving for x: Subtracting 3x both sides of the equation:
7x-3x=3x+4-3x
Subtracting:
4x=4
Dividing both sides of the equation by 4:
4x/4=4/4
Dividing:
x=1
Then we can determine the length of LM:
LM=2x+6
Replacing x by 1 in the equation above:
LM=2(1)+6
LM=2+6
LM=8
and because LM is half the length of the base of the triangle (JK)
LM=(1/2) JK
Replacing LM by 8:
8=(1/2) JK
Multiplying both sides of the equation by 2:
2(8)=2(1/2) JK
16=(2/2) JK
16=(1) JK
16=JK
JK=16
Answer:
Interest Rate : 0.0346 or 3.46%
Step-by-step explanation:
• 429.2=350*(1+x)^6
• 429.2/350= (1+x)^6
•(429.2/350)^(1/6)= 1+x
•(429.2/350)^(1/6)-1= x
Check work:
350*(1+0.0346)^6=429.2

Answer:
-7/3 & 5/2
Step-by-step explanation:
3x +7 = 0
3x = -7
x = -7/3
2x-5=0
2x = 5
X = 5/2
