Answer:
The opposite sides of a parallelogram are congruent, then
19x - 9 = 13x + 15 ( subtract 13x from both sides )
6x - 9 = 15 ( add 9 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4
---------------------------------------------
Consecutive angles are supplementary, sum to 180° , that is
10y - 37 + 4y + 7 = 180
14y - 30 = 180 ( add 30 to both sides )
14y = 210 ( divide both sides by 14 )
y = 15
Then
∠ R = 10y - 37 = 10(15) - 37 = 150 - 37 = 113°
Then
∠ P = 113° ( opposite angles are congruent )

A intersect B '
Answers
Answer:
{Monday, Tuesday, Wednesday, Thursday}
Step-by-step explanation:
First we need to get the complement of B i.e B'
B' are the set in the Universal set but that are not in B
B' = {Monday, Tuesday, Wednesday, Thursday}
A= {Monday, Tuesday, Wednesday, Thursday, Friday}
A intersect B ' are the days of the week that are common to both sets;
A intersect B ' = {Monday, Tuesday, Wednesday, Thursday}

The mean of the numbers 22,18,(2y+1),10 and 20 is 15.
find the median.
Answers
Answer:
Median is 18
Step-by-step explanation:
Firstly you have to fine y by using your mean
Therefore, 22+18+(2y+1)+10+20 divide it by the number of the mean that is the sum of the number divide by the total number of the mean which is 5 =15
22+18+2y+1+10+20 over 5 =15
71+y over 5 =15
Cross multiple
71+y=75
y=4
22,18,9,10, 20
Rearrange
9,10,18,20,22
The median is 18

Hello Solving Equations Puzzle
Answers
Green crescent should be 11
2+2+11=15
Pink trapezoid should be 15
30-15=15
15=15
Answer:
Pink Trapezium = 30 as 30 x 1 = 30
Purple Diamond = 2 as 2 x 2 = 4
Green Moon = 7.5 as it shares the line with 4 it goes 4 x 7.5 = 30
The weight of the line is dividing line just the same as multiple when we find the numbers from dividing. But work out 2 x 2 first. then use that number to divide into 30 to find 7.5.
When we show the values see below. We have 30 also for the second line so both lines are equivalent
Step-by-step explanation:
I would multiply as addition is just too easy.
Pink Trapezium is 1 x 30 = 30 = 30/1 = 30 value
Purple diamond = 2 x 2 = 4 = 4/2 = 2 value
Green Moon is 30/4 = 7.5 value

x is inversely proportional to the square root of y
When x = 12, y = 9
Find the value of x when y= 81
Answers
Answer: 4
Step-by-step explanation:
The formula for inverse proportion is x = k / y. Since x is inversely proportional to the square root of y. This will be:
x = k / ✓y
When x = 12, y = 9
We have to calculate the constant of proportionality, k which will be:
12 = k / ✓9
12 = k / 3
k = 12 × 3
k = 36
To find the value of x when y = 81 will be:
x = k / ✓y
x = 36 / ✓81
x = 36 / 9
x = 4
Therefore, x = 4 when y = 81.
