Answer:

-3

Step-by-step explanation:

Since x=1, we can simplify the equation to 9+7y=-12.

To find the value of 7y, we first have to find what is missing.

-12-9=-21, so 7y has to be equal to -21. -21/7 equals -3, so y=-3.

An urn contains 8 green and 9 white balls. Six balls are randomly drawn from the urn in succession, with replacement. That is, a
gulaghasi [49]

Answer:

The probability is 0.022

Step-by-step explanation:

Firstly, we need to get the total number of balls in the urn

mathematically, we have this as ;

8 + 9 = 17

now, the probability of selecting a white ball will be the number of white balls divided by the total number of balls

Mathematically, we have this as 9/17

Now, since the event is carried out with replacement, the probability for the six times is the same

So, we have the probability as;

(9/17)^6 = 0.022

-5x=25 how to solve this problem ​
Sidana [21]
X = -5

The goal of this problem is to solve for x.

To solve x in this problem you need to find a way to get it by itself on the left side, the way to do this is divide -5x by -5.

You then also have to do the same for the right side. This gives you -5.

What's the answer I'm not sure.
FinnZ [79.3K]
For the first one EF is 119 degrees now since that's made with two radii it makes a central angle so whatever that arc is the central angle will be the same. fro the second one since SRQ is 52 degrees you just take that and subtract it from 180 to get SQ. I'm not quite sure about the third one. the forth you are taking the measurement of the arc its connected to and dividing that by 2 so it would be 71 degrees. I'm pretty sure in right.
