Answer:
Heather sent 28, Pablo sent 19, and Shen sent 76.
Step-by-step explanation:
This will be your equation
123 = H (Heather) + P (Pablo) + S (Shen)
This is the extra stuff
P + 9 = H
4P = S
Substitute so there is only P then use that to solve for the rest
123 = P + 9 + P + 4P
Then solve
123 = 6P + 9
123 - 9 = 6P + 9 - 9
114 = 6P
19 = P
Then substitute for the extra equations
19 (P) + 9 = 28 (H)
19 (P) * 4 = 76
Answer:
The Falcones have to travel at 25 m/h to make the trip in 2 hours.
Step-by-step explanation:
In order to find the answer you have to use the formula to calculate speed:
speed=distance/time
distance=50 miles. The stament indicates that the distance between Syracuse and Buffalo is 1 inch and that the map has a scale of inch = 50 miles.
time=2 hours
Now, you can replace the values on the formula:
speed=50 miles/2 hours
speed=25 m/h
According to this, the answer is that the Falcones have to travel at 25 m/h to make the trip in 2 hours.
Slope = (-5-1)/(7+1) = -6/8 = -3/4
Perpendicular slope = 4/3
Midpoint = ((-1+7)/2 , (1+(-5))/2) = (3, 3)
equation:
y = mx + c
y = 4/3 x + c
at point (3, 3)
3 = 4/3(3) + c
c = 3 - 4 = -1
y = 4/3 x - 1 or 3y = 4x - 3
