Replacing y in the second equation gives;
5x+2(-3x-2)=15
5x-6x-4=15
-x-4=15
-x=19
x=-19

y=-3(-19)-2
y=57-2
y=55

Find the equation of a plane that is perpendicular to the vector −4i⃗ −4j⃗ −k⃗ and passing through the point (−2,−5,5)
vredina [299]

hello ....

the equation of a plane that is ;  ax+by+cz +d =0

the vector perpendicular to this plane is : V(a,b,c)

in this exercice ; a = -4  b= -4  c = -1

then: the equation of a plane that is ;  -4x-4y-z +d =0

but the plane  passing through the point (−2,−5,5) :

-4(-2)-4(-5)-(5) +d =0

23+d =0

d =-23

the equation of a plane is : -4x-4y-z-23 =0

A school district held a meeting for all its physical education teachers.The number of women attending was 5 more than twice the
Alecsey [184]

Answer:

The system of equation is w+m=53 and w=2m+5.

There are 16 men who are attended the meeting.

Step-by-step explanation:

Given,

Total number of teachers = 53

Solution,

Let the total number of women teachers be 'w'.

And also let the total number of men teachers be 'm'.

So, total number of teachers is the sum of total number of women teachers and total number of men teachers.

This can be framed in equation form as;

w+m=53\ \ \ \ equation\ 1

The system of equation is w+m=53.

Now according to question,

The number of women attending was 5 more than twice the number of men attending the meeting.

So this can be framed in equation form as;

w=2m+5\ \ \ equation\ 2

Now we insert the value of w from equation 2 in equation 1, we get;

2m+5+m=53\\\\3m+5=53\\\\3m=53-5=48\\\\m=\frac{48}{3}=16

Now we solve for 'w';

w=2m+5=2\times16+5=32+5=37

Hence there are 16 men who attended the meeting.

And also there are 37 women who attended the meeting.
