Answer:
y = 12
Step-by-step explanation:
We first need to solve for x
(6x - 11)° and (4x + 23)° are vertically opposite angles and are congruent, so
6x - 11 = 4x + 23 ( subtract 4x from both sides )
6x - 4x - 11 = 4x - 4x + 23 ( simplify both sides )
2x - 11 = 23 ( add 11 to both sides )
2x - 11 + 11 = 23 + 11 ( simplify both sides )
2x = 34 ( divide both sides by 2 )
x = , that is
x = 17
Then
4x + 23 = 4(17) + 23 = 68 + 23 = 91
(9y - 19)° and 91 are a linear pair and sum to 180°
sum the 2 angles and equate to 180
9y - 19 + 91 = 180 ( simplify left side )
9y + 72 = 180 ( subtract 72 from both sides )
9y + 72 - 72 = 180 - 72 ( simplify both sides )
9y = 108 ( divide both sides by 9 )
y = , that is
y = 12
Let the number of yellow cubes be x
Yellow Cubes = x
Blue Cubes = 3x
Green = 5 (3x) = 15x
Ratio : Yellow : Blue : Green = 1 : 3 : 15
P(Yellow) = 1/19
Answer: 1/19
Number 12 have factors 12 = ( 1,2,3,4,6,12)
Number 18 have factors 18= ( 1,2,3,6,9,18 )
According to this we can conlude that numbers 12 and 18 have in common (1,2,3 and 6).
Good luck!!!
2 and 6 can go into it evenly
To find the missing x value in a table, one must understand the relationship or pattern between the numbers. This can involve operations like addition, subtraction, multiplication, or division. It's good practice to verify answers by plugging the x value back into the equation.
I understand you need help asap with understanding how to find the missing x in the table. It's quite essential to know the function rule or pattern that relates the missing value of x to other numbers in the table. Typically, some form of mathematical operation (addition, subtraction, multiplication, division or a combination of these) connects the numbers. Once we identify this operation or pattern, we can apply it to find the missing x values.
For example, if the pattern in the table is "add 3" then if y=5 and x is missing, you'll add 3 to 5, making x=8. Another example, the pattern is "multiply by 2", then if y=7 and x is missing, you'll multiply 7 by 2 making x=14.
It's always good to cross-verify your answer by plugging the x value back into the equation or pattern and see if it fits correctly. And don't worry about giving the brainliest; your understanding is more important!

The second term of this given geometric series is
A geometric sequence's finite or infinite terms are added together to form a geometric series. The geometric series that corresponds to the geometric sequence a, ar, ar2,..., arn-1,... is a + ar + ar2 +..., arn-1 Clearly, "series" means "sum." The phrase "geometric series" refers specifically to the total of words with a common ratio between every adjacent pair of them. Finite and infinite geometric series are both possible.
Given a geometric series 1/4 + × + 1/36 + 1/108 +.....
In this series first term(a) = 1/4
second term(a₂) = x
Third term (a₃) = 1/36
ratio(r) = a₄ /a₃
ratio (r) = 1/3
The formula for the nth term of a geometric series is aₙ = arⁿ⁻¹ .....(1)
put these values in equation (1)
a₂ =
a₂ = 1/12
Hence, the second term for the geometric series 1/4+×+1/36+1/108+... is 1/12.
