Answer:
887 and 792 km per hour
Step-by-step explanation:
Lets call the first plane A and the second B
we know that: a=b+95
We can say that 3358=2b+(2b+190)<=A
When solved, we get 3168=4b
b=792 km per hour.
Go back to step two. A=b+95, so A=792+95=887 km per hour
The two planes rates are 887 km per hour and 792 km per hour.
If she already gets the first two, thats a given 100% situation. then it is just 1/4
Answer:
1/2
Step-by-step explanation:
(-9,6), (-3,9)
y2 - y1 = 9 - 6 = 3
x2 - x1 = -3 - -9 = 6
= 3/6 = 1/2
So, first set the two Y values equal to each other.
4x+9 = -1+8x
Add and subtract values to both sides making the x coordinates on one side:
4x = 10
Finally, divide.
x = 10/4 = 2.5
