Answer:

$x=5$

Step-by-step explanation:

CE = EB since E is the midpoint of CB (proven by AD intersecting it).

If CE=EB, then:

$2x=15-x\\$

Add $x$ to both sides

$3x=15\\$

Divide both sides by 3

$x=5$

Answer:

Step-by-step explanation:

Since the diagonals of a parallelogram bisect each other, the two halves must be equal. Therefore:

$15-x=2x \\\\15=3x \\\\x=5$

Given the line below.

Yanka [14]

We have to write the equation of the line, in point-slope form. Given an identified point (x1, y1) as the point (-2, 2). So that means x1=-2 and y1=2

Value of slope "m" is not given so i will keep using "m" for the slope. In case value of slope m is given in the problem then you can plug that number in place of m.

Point slope formula is given by:

$y-y_1=m\left(x-x_1\right)$

plug the given values into above formula :

$y-\left(2\right)=m\left(x-\left(-2\right)\right)$

$y-2=m\left(x+2\right)$

so the required answer in point slope form is $y-2=m\left(x+2\right)$

A sports club has 38 members. They all play either squash or tennis.

Brut [27]

Step-by-step explanation:

Since we have given that

Total number of members in a sports club = 38

Number of women in the club = 14

Number of women play tennis =10

Number of men play tennis = 8

Since they all play either squash or tennis.

Total number of men in the club is given by

$38-14\\\\=24$

So, number of men playing squash is given by

$24-8\\\\=16$

Number of women playing squash is given by

$20-16\\\\=4$

so, the table is shown below :

Men Women Total

Tennis 16 4 20

Squash 8 10 18

Total 24 14 38
