Basically when you reflect something, you can think of it as a mirror, you flip it the opposite way.
Excuse my poor drawing skills, but I made a graph and a drawing of what I mean.
Treat as fraction
28/4
common factor is 4
divide by 4 or undistribute the 4
7/1
7:1 is simplifed ratio
Answer:
QD = 13
Step-by-step explanation:
According to the Centroid theorem of a triangle, the Centroid is ⅔ of the distance from every vertex angle to the midpoint of the side opposite to each of them.
By this we can deduce that:
QD = ⅔(QD + DK)
Substitute
QD = ⅔(QD + 6.5)
Multiply both sides by 3
3*QD = 2(QD + 6.5)
3QD = 2QD + 13
Subtract both sides by 2QD
3QD - 2QD = 13
QD = 13
Answer:
A
Step-by-step explanatiWe know x is between 1 and 3 so the best estimate is 2 even though the answer could also be 3 but that will be skewed.
Answer:
A
D is 13 km
Step-by-step explanation:
30min:60h=0.5h *14km/h=7km
7-4=3km(AB)
4km(BC)
2*3=6km(CD)
3+4+6=13km
