-9y+11= -6y+8
-9y+11-11=-6y+8-11
-9y=-6y-3
-9y+6y=-6y-3+6y
-3y=-3
Answer: y=1
Answer:
From the level of high tide to low tide, it's 18 feet.
Step-by-step explanation:
To find the change in water level, we multiply the rate (3 ft / hr) by the time (6 hrs), obtaining 18 ft.
The water level changes by 18 ft.
Since 7 yd is 21 ft you will have to
add 15 ft to 21 ft (36 ft)
and then divide by two
your answer is 18 ft
Answer: The probability that his friend doesn't make a shot until his 5 th attempt is 0.00128.
Step-by-step explanation:
Since we have given that
Probability of making his shot = 80%
Probability of missing his shot = 20%
We need to find the probability that his friend doesn't make a shot until his 5th attempt.
So, our required probability would be

Hence, the probability that his friend doesn't make a shot until his 5 th attempt is 0.00128.
I think it would be it has no solutions, because if you solve for z, the z's cancel each out and you would get 0=2 with is not true, so there would not be any solutions.
4.5z=4.5z-4.25+6.25
4.5z-4.5z=-4.25+6.25
0=2
no solution
