82-10=72
72/6=12
answer is 12
I believe the trains speed average was about 34 km/h
Answer:
123
Step-by-step explanation:
1 bag = 13 cookies
9 bags x 13 cookies = 117 cookies
117 cookies + 6 cookies that he already has = 123 cookies
Dale have 123 cookies in total.
The point (6, 3) will make this a parallelogram.
In a parallelogram, both pairs of opposite sides are parallel. From the choices we have for point D, we want to find the coordinates of the point so that the slope from B to D is the same as the slope from A to C, since parallel lines have the same slope.
m = (y₂-y₁)/(x₂-x₁) = (3-0)/(3-0) = 3/3 = 1 (from point A to C)
This means that for every 1 we go up from point B, we want to go 1 right as well. 3 up and 3 right will get us the point (6, 3), which will give BD the same slope as AC.
