Answer:
x= -1.118
Step-by-step explanation:
Firstly you need to start with the bracket
-5(5x +5) + 3(5x +3)
=( -25x +25) + (15x +9)
= -25x +25 +15x +9= -4x -6x
secondly you join the like terms together
25+9= -4x -6x +25x -15x
34= -38x
-38x ÷ 34
x= -1.118

In an office, there are 75 women and 125 men .Find the ratio of
the number of men to the number of women.
Answers
Given:
In an office, there are 75 women and 125 men.
To find:
The ratio of the number of men to the number of women.
Solution:
We have,
Number of men = 125
Number of women = 75
The ratio of the number of men to the number of women is:
[tex]\text{Required Ratio}=\dfrac{\text{Number of men}}{\text{Number of women}}[/tex]
[tex]\text{Required Ratio}=\dfrac{125}{75}[/tex]
[tex]\text{Required Ratio}=\dfrac{5}{3}[/tex]
[tex]\text{Required Ratio}=5:3[/tex]
Therefore, the ratio of the number of men to the number of women is 5:3.

5m - 2n=4
m - 4n = -1
20 3x + 5y = 11
2x - y=3
Answers
Answer:
Step-by-step explanation:
5m - 2n = 4
m - 4n = -1 add 4n to both sides m - 4n + 4n = 4n - 1
m = 4n - 1 now substitute for m into the first equation
5(4n -1) - 2n = 4
20n - 5 - 2n = 4 combine the n coeffients and add 5 to both sides
18n - 5 = 4 + 5
18n = 9 solve for n by dividing 18 by both sides
18 n/18 = 9 /18
n = 1/2 now find for m using m = 4n - 1 m = 4(1/2) - 1 m = 2 -1 = 1
m = 1 (1, 1/2) solves the two equations
3x + 5y = 11 equation 1
2x - y = 3 multiply both sides by 5 so when you add the two equation
the y term is eliminated (becomes zero)
5(2x-y) = 5(3)
10x - 5y = 15 equation 2 add equation 1 and equation 2
3x + 5y = 11 add the like terms
10x - 5y = 15 add the like terms
(3x + 10x) + (5y - 5y) = (11 + 15)
13x + 0 = 26 the y tern is gone now solve for x
13x = 26
13x/13 = 26/13
x = 2 now find y using 2x - y = 3
2x - y = 3 add y and subtract 3 from both sides
2x - y + (y - 3) = 3 + (y - 3)
2x - 3 = y we already know x = 2
2(2) - 3 = y
4 - 3 = y
1 = y answer (2,1) solves the two equaitons

3. The y-intercept is -4 and the slope is positive 2.
4.Substitute the values and check
Answer and Step-by-step explanation:
3.
Before we look at the answer choices, lets analyze the graph.
We see that as the graph goes right, the y values are positive, and that as the graph goes left, the y values become negative/decrease. (Graph, as in the line on the graph).
That means the graph has a positive slope. So we can get rid of any negative slopes (answer choices A and C).
Now, we look to see the rate of change of the graph. How many units does the graph go up and right right?
We see that the graph has a rate of change of 2, so that is the slope.
This means that answer choice B is the answer. The equation shows that it goes down 4 units as well, which is what the graph shows as well.
4.
For this one, we need to see the pattern in the table.
When we put 2 in for n, we get 6. When we put 3 in for n, we get 8. And when we put 4 in for n, we get 10.
Answer choice D works for this. If we plug 2, 3, and 4 in for this expression, we get:
2(2) + 2 = 4 + 2 = 6
2(3) + 2 = 6 + 2 = 8
2(4) + 2 = 8 + 2 = 10
So answer choice D is the answer.

Answer:
468 Square Centimeters
Step-by-step explanation:
Surface area can be calculated by adding the areas of each face on a prism:
The rectangle to the left is a 9 by 10. The formula for the area of a rectangle is length times width, so we can get the area by multiplying 9 and 10: 9*10=90To the right of that rectangle is another rectangle. This time it's a 10 by 12, as we can see in the picture. Multiply 10 and 12: 10*12=120The last rectangle, on the right, is a 15 by 10. Multiply 15 and 10: 15*10=150Now look at the triangle on the top. The formula for the area of a triangle is base times height divided by 2. The base of the triangle in this case is the bottom side, 12. The height is how tall the triangle is, 9. Multiply 9 and 12: 9*12=108. Divide that by 2: 108/2=54Finally, look at the triangle on the bottom. It is exactly the same as the one on the top, with a base of 12 and a height of 9. Since it is exactly the same, we know that it has the same area too: 54Add up the areas: 90+120+150+54+54=468please let me know if the answer or explanation is incorrect, hope this helps :)

The perimeter of the square is 64 inches. What is the perimeter of the shaded region?
Answers
Answer:
54.94 inches
Step-by-step explanation:
First you need to find the radius of the semi-circles within the square.
You find this by dividing the perimeter by 8
64/8 = 8
now use the formula πr^2 to find the area of the semi circle
π8^2 = 201.06
Now find the total area of the square and subtract it from the area of the two semi circles to find the shaded region
16*16 = 256
256-201.06 = 54.94
