2 (n+7)=3n Hopefully this helps !!!

Answer:

2(n+7)=3n

Step-by-step explanation:

"A number" is unknown so just create a variable in this case I made it "n."

We know that sum means to add so add the variable n and 7 then going back up the beginning we see it says twice so we take that sum and times is by two and I'm using parentheses to show this. The next part of the problem says "Is" and that's an indication of an equal sign. We'll then put the equal sign after the problem we just filled out and finish off the equation with 3 times the number meaning we'll put the 3 and next to each other as another way of multiplying.

Answer:38x-34

Step-by-step explanation:

f(x)=x^2+3x-7

g(x)=5x-3

We multiply the entire F equation times two, (x^2+3x-7)*4=

(4x^2+12x-28)

Now the entire g equation by 2, (5x-3)*2

(10x-6)

Now we add both equation

(4x^2+12x-28)+(10x-6)

(4x^2+22x-34)

(4x*4x+22x-34)

(16x+22x-34)

38x-34

Hopefully this is correct :)))

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.
