G=b-3 and c=29=b+g substituting the first into the second gives you...
b+(b-3)=29
2b-3=29 add 3 to both sides
2b=32 divide both sides by 2
b=16
So there were 16 boys and (29-16) 13 girls in Ms. Wong's class.
Speed of truck= x
speed of train=x-30
A loaded moving truck is traveling 30 mph faster than a freight train. in the time it takes the train to travel 135 miles, the truck travels 225 miles. find the speed of the truck.
A loaded moving truck is traveling 30 mph faster than a freight train...
(x-30)=speed of train
the time it takes the train to travel 135 miles, the truck travels 225 miles...
135/(x-30)=225/x
the you multiply on both sides the x values and get...
135x=225x-6750
then you subtract 225x on both sides...
-90x=-6750
then you divide -90 on both sides...
x=75
the speed of the truck is 75mph

Answer:
C
Step-by-step explanation:
The Triangle Angle Bisector theorem says that and angle bisector will divide the opposite side into 2 segments that are proportional to the other 2 sides of the triangle.
Thus, from the definition, we can say 28 and x is proportional to 14 and 8.
We can set up a ratio, cross multiply, and solve for x:
So the value of x is 16 and thus the correct answer is C
A median of a triangle is a segment that spans from the vertex to the midpoint of the opposite side.
Every triangle has three medians.
