"<span>y/5+8=7, what is the value of y/5-2?" Simplify the first equation:
y/5 = 7 - 8, or -1, so y/5 = -1, or y = -5.
Then y/5 - 2 equals -5/5 - 2, or -3.</span>
Answer:
x = 36
Step-by-step explanation:
Rearrange the equations before solving simultaneously
4y = -5x - 28
2y = 7x - 24
now subtract
4y - 2y = 2y
5x - 7x = -2x
-28 - - 24 = -4
put these values together.
2y - 2x - 4.
2y = 2x + 4
y = 2x + 4 / 2
y = x + 2
substitute this into one of the 1st equations in the question.
5x = -4(x + 2) + 28
5x = -4x + 8 + 28
5x = -4x + 36
9x = 36
x = 4.
It can help you cause when you estimate your going back and putting the right number
There are 8 possible outcomes so that means the probability will have a denominator of 8.
Now, there is only one of the eight outcomes that has zero tails.
Therefore the probability of getting zero tails after tossing a fair coin three times in succession is
