Answer:

A

x =  - 4

Step-by-step explanation:

do the Parentheses first so----

do Parentheses first which would then be 8x-3=10x+5

then put "10x in the middle of 8x and -3

so

8x - 10x - 3 = 5

then 8x-10x which would equal -2x

then you would be left with

- 2x = 5 + 3

add the 5+3 ------>> -2x=8

(divide both sides)

x =  - 4

Which of the following equations describes the line shown below? (1, 10) (-3, 2)
Greeley [361]
(1,10)(-3,2)
slope = (2-10) / (-3-1) = -8/-4 = 2

y = mx + b
slope(m) = 2
(1,10)...x = 1 and y = 10
now we sub and solve for b, the y int
10 = 2(1) + b
10 = 2 + b
10 - 2 = b
8 = b

equation is : y = 2x + 8.....or 2x - y = -8

What is 3x-10+2x+3x+x+20+2x+10+x-20
kodGreya [7K]

Answer:

12x

Explanation:

3x − 10 + 2x + 3x + x + 20 + 2x + 10 + x − 20

= 3x + −10 + 2x + 3x + x + 20 + 2x + 10 + x + −20

Combine Like Terms

= 3x + −10 + 2x + 3x + x + 20 + 2x + 10 + x + −20

= (3x + 2x + 3x + x + 2x + x) + (-10 + 20 + 10 + −20)

= 12x

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.
