They are vertical angles meaning they both have the same angle thus you can set the two equations equal to each other
9y+7 = 2y+28
Solve for y
Plug your y into one of the equations and you’ll get your angle
Answer:
3.143
Step-by-step explanation:
Since you're rounded it to the third decimal, you look at the fourth one. And since the fourth one is 8, ur going round 2, which is the third decimal to 3.
Answer: 7x+y+8
Step-by-step explanation:
Combining like terms is just like what it sounds. You take the like terms, or terms that have the same variables and such, and add them together.
For this problem, we can see that 12x and -5x are like terms because they both consist of a numerical coefficient and the variable x.
We can see that -3y and 4y are like terms because they both have a numerical coefficient and y for variable.
Now, we can combine like terms.
12x-3y+8-5x+4y [combine like terms]
7x+y+8
The probability of selecting or choosing seven marbles is 0.29.
Let E be the event of choosing seven red marbles.
According to the given.
Total number of balls in an urn = 13 + 11 = 24
Total number of red marbles = 13
Total number of blue marbles = 12
Now, the total number of ways of selecting 12 marbles from 24 = 
And the number of ways of selecting 7 red marbles = 
As, we know that, the probability of any event can be calculated as by taking the ratio of favroble outcomes to the total number of outcomes.
Therefore, the probability of selecting or choosing seven marbles is given by
⇒ P(E) = 
⇒ P(E) = 792792/2704156
⇒P(E) = 0.29
Hence, the probability of selecting or choosing seven marbles is 0.29.
