PQRS Is A Parallelogram. Solve For X.Plz Help

Answers

Answer 1

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 )

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

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.

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
