The number of workers in the company is given as follows:
3900 workers.
How to obtain the number of workers in the company?The number of workers in the company is obtained applying the proportions in the context of the problem.
From the problem, we have that:
70% of the workers are women.1170 of the workers are not women.Hence 30% of the workers is equivalent to 1170, hence the number of workers in the company is obtained as follows:
0.3x = 1170
x = 1170/0.3
x = 3900 workers.

substitution y=2y-2 and y=2x-5y=1
Answer:
We can solve for y in the equation y = 2y - 2 by substituting y = 2x - 5.
Starting with y = 2y - 2, we substitute y = 2x - 5:
2x - 5 = 2(2x - 5) - 2
Expanding the right side:
2x - 5 = 4x - 12
Next, we isolate y by subtracting 2x from both sides:
-2x - 5 = 4x - 12
Adding 2x to both sides:
-5 = 6x - 12
Adding 12 to both sides:
7 = 6x
Finally, we divide both sides by 6 to solve for x:
x = 7/6
So, y = 2x - 5 = 2(7/6) - 5 = 7/3 - 5 = -14/3.
Therefore, y = -14/3 is the solution to the system of equations y = 2y - 2 and y = 2x - 5.

Lin rolls a six-sided number cube then chooses one card from a deck of three cards numbered 1 through 3. What is the probability that the number cube and the card have the same number?
The probability that the number cube and the card have the same number is 2/39.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Outcomes of cube = { 1, 2, 3, 4, 5, 6}
Outcome of Card = {1, 2, 3} from each group.
So, we have three number both in common as {1, 2, 3}
So, the probability that the number cube and the card have the same number is
= 1/6 x 16/52
= 8/156
= 2/39

show solutions if any 20. -7x + 7y = 1
2x - 2y = -18
The equations are two parallel lines, then the system of equations has no solutions.
How to solve the system of equations?Here we have a system of equations:
-7x + 7y = 1
2x - 2y = -18
Now, if we multiply the second equation by (7/2) we will get:
(7/2)*(2x - 2y) = -18*7/2
7x - 7y = -63
If we multiply this by -1 we will get:
-1*(7x - 7y) = -1*-63
-7x + 7y = 63
Then the system of equations becomes:
-7x + 7y = 1
-7x + 7y = 63
Notice that the left side is equal in both equations but the right side is different, then the system has no solutions.

Question 48 what is the area if the mat is 184 in
The length and width of the rectangular board is 27 inches and 23 inches respectively
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the area of the mat be = 184 inches²
Area of Rectangle = Length x Width
Substituting the values in the equation , we get
Let the area of the larger rectangle be = ( 2x - 3 ) ( x + 8 )
Let the area of the smaller rectangle be = ( 2x - 7 ) ( x + 4 )
Now , the area of mat = area of the larger rectangle - area of the smaller rectangle
So , 184 = ( 2x - 3 ) ( x + 8 ) - ( 2x - 7 ) ( x + 4 )
On simplifying the equation , we get
2x² - 3x + 16x - 24 - [ 2x² + x - 28 ] = 184
On further simplification , we get
12x + 4 = 184
Subtracting 4 on both sides of the equation , we get
12x = 180
Divide by 12 on both sides of the equation , we get
x = 15
So , the length of the board = ( 2x - 3 ) = 27 inches
And , width of the board = ( x + 8 ) = 23 inches
Hence , the dimensions of the rectangular board is 27 x 23 inches²

The algebraic fraction which is an equivalent fraction with the denominator 24a^3b^2 is 15b/24a^3.
To find an equivalent fraction with the denominator 24a^3b^2, we need to find a common denominator for the two fractions 5b and 8a^3. This common denominator is 24a^3b^2.
To find an equivalent fraction for 5b, we can multiply both the numerator and denominator by the same factor to obtain the desired denominator. To do this, we need to find a factor that would give us a denominator of 24a^3b^2 when multiplied with 8a^3.
The factor that would give us a denominator of 24a^3b^2 is 3.
