Answer:
x=-0.4
Step-by-step explanation:
ok you have to visualize this line
P Q R
O---------------------O-----------------------O
3x+14 7x-10
so to make the equation of PR you would add PQ and QR together.
3x+14+7x-10
add your like terms
10x+4
solve for x
10x+4=0
subtract 4 from each side
10x=-4
divide both sides by 10
x=-2/5 fraction
x=-0.4 decimal
x=6
A midpoint is the middle point of a line segment, therefore it is equal distances from both ends of the segment.
This means that PQ and QR have the same length. So all we have to do is set each value equal to each other, and then solve for X.
15.1
The = sign
1 11/20 = 31/20 = 1.55 and 1.55 =1.55
A because it's self explanatory.
