The answer is option C. Both Friedrich and Jung have the most debt. Hope I could help! :D
X=5. y=35.
To solve, substitute the 7x into the equation for y. Solve. You get x=5. Then put that into your first equation. Solve. You get y=35. Hope that helps!!
Answer:
67 1/2 is a mixed number
Step-by-step explanation:
The volume of a prism, is the area of the cross section X the length:
In this case it is base × height × length:
6 × 4.5 × 2.5 = 67.5cm^3
= 67 1 / 2 as a mixed number
H=0
Therefore:
144t-16t²=0
t (144-16t)=0
We have two equations:
1)
t=0 (when the ball is released)
2)
144-16t=0
-16t=-144
t=-144 / -16=9 (this is the time )
Answer: the ball hit the ground in 9 s.
