Answer:
w = 7, and w = 8 is correct
Step-by-step explanation:
1. Why 5 does not work
a. Substitute 5 into the equation
5w-10>20 --> 5(5) - 10 > 20
b. Solve the equation
Remember Pemdas:
P- Parentheses First
E- Exponents Second
M- Multiplication Third
D- Division Fourth
A- Addition Fifth
S- Subtraction Sixth
We are not working with Exponents and Parentheses, but we are working with the rest.
Since there is no P and E, that means that multiplication is first
5(5)-10>20 - 5(5) = 5 x 5 = 25
Now all is left is to subtract:
25 - 10 = 15
15 > 20 Is not true.
2. Why 6 does not work
a. Substitute
5w-10>20 --> 5(6) - 10 > 20
b. Solve
5(6) = 5 x 6 = 30
30 - 10= 20
20 > 20 is not true
Just like you are not greater than yourself, 20 can not be greater than its own self.
3. Why 7 and 8 work (7a, 7b is 7; 8a, 8b is 8)
7a. Substitute
5w-10>20 --> 5(7) - 10 > 20
8a. Substitute
5w - 10 >20 --> 5(8) - 10 > 20
7b. Multiply and subtract
5(7) = 5 x 7 = 35
35 - 10 = 25
25 > 20
25 is greater than 20
8b. Multiply
5(8) = 5 x 8 = 40
40 - 10 = 30
30 > 20
30 is greater than 20
Hereby, w = 7, and w = 8

An elevator at a department store must carry fewer than 17 people at a time. An elevator operator is present in the elevator at all times. If x customers can travel in the elevator with the elevator operator, which inequality represents this situation?
A.
x + 1 < 17
B.
x > 18
C.
x + 1< 16
D.
x < 17
E.
x + 1 > 18
Answer:
A. x + 1 < 17
Step-by-step explanation:
An elevator at a department store must carry fewer than 17 people at a time. An elevator operator is present in the elevator at all times. If x customers can travel in the elevator with the elevator operator, which inequality represents this situation?
x = customers
1 = the elevator operator
< 17 = the amount of people that can be in the elevator at a time
Together, we get our inequality:
x + 1 < 17
The customers + the operator in the elevator should not be greater than 17.
Hope this helps!

The width of a rectangle is 7x – 9.5 feet and the length is 9.5x + 10 feet. Find the perimeter of the rectangle.
Answer:
33x + 1
Step-by-step explanation:
Perimeter of a rectangle: P = 2(l + w) OR P = 2(l) + 2(w)length (l) = 9.5x + 10width (w) = 7x - 9.5P = 2(l + w)
P = 2(9.5x + 10) + 2(7x - 9.5)
P = 19x + 20 + 14x - 19
P = 19x + 14x + 20 - 19
P = 33x + 1

First take the base which is 12.5 KM and multiply it by 3.7 KM which equals 46.25. Then you need to divide by 2, which is 23.125 square KM.
Hope this helped.
Answer:
A) 23.125 square kilometers
Step-by-step explanation:
Area of a right triangle: 1/2*b*hb = 12.5 kmh = 3.7 kmA = 1/2*12.5*3.7
A = 1/2*46.25
A = 23.125 square kilometers

where do y = -x + 8 and y = x - 2 intersect
Answer:
(5,3)
Step-by-step explanation:
To find where two lines intersect you let them equal to each other.
-x + 8 = x -2
Add 2 on both side
-x + 10 = x
Add x on both sides
10 = 2x
Divide 2 on both sides
5 = x
Now plug x into both equations
y = -5 + 8 = 3
y = 5 - 2 = 3
so y = 3
The point they intersect is (5,3)

What is the area of this figure?
Select from the drop-down menu to correctly complete the statement.
The area of the figure is 'blank' cm².
Answer:
The area is 146cm squared
Step-by-step explanation:
Starting with the top portion, The formula for the area of a trapezoid is a = (base 1 + base 2) / 2 * h | (14 + 4) /2 *10 = 90.
Now for the bottom part, We know that the height of the top of the figure is 10 and that the overall figure height is 18. To find the height of the triangle at the bottom we would do 18 - 10 = 8.
The formula for finding the area of a triangle is b x h / 2 = a. 14 * 8 / 2 = 56.
Finally, we add our results. 90+56=146.
find the areas of the trapezoid's

Answer:
y = 3n - 2
Step-by-step explanation:
so to find the slope or rate of change we use the equation
y 2 - y1 / x2 - x1
soo lets use the points
(1, 1) and (2, 4)
4 - 1/ 2 - 1
3/1
3
y = 3n + b
now we substitute a point we did not use yet
(3, 7)
7 = 3(3) + b
7 = 9 + b
b = -2
y = 3n - 2
now check
(4,10)
10 = 3(4) - 2 ?
10 = 12 - 2 ?
10 = 10
Answer:
y = 3n - 2
Step-by-step explanation:
y = mx + b or y = nx + b
Where m or n represents the slope
[tex]m\ or\ n=\frac{y_2-y_1}{x_2-x_1} \\\\m\ or\ n=\frac{4-1}{2-1} \\\\m\ or\ n=\frac{3}{1} \\\\m\ or\ n=3[/tex]
y = 3n + b
(n, y) ==> (2, 4)
y = 3n + b
4 = 3(2) + b
4 = 6 + b
-6 -6
-2 = b
y = 3n - 2
Check your answer using (2, 4):
y = 3n - 2
4 = 3(2) - 2
4 = 6 -2
4 =4
This statement is correct

1). y=x;(2,3) Tell whether the ordered pair is a solution of the equation. 2) Y=3x -2; (1,1)
Answer:
1) no, (2,3) is not a solution of y=x.
2) yes, (1,1) is a solution of y=3x-2
Step-by-step explanation:
When you have a point, the first number is x and the second number is y, (x,y).
If you substitute the numbers in for x and y, you will get a true statement if the point is a solution.
Look at y = x, put in 2 for x and 3 for y.
You get 3 = 2, that's false. So (2,3) is NOT a solution of y = x.
Then consider
y = 3x - 2; fill in 1 for x and 1 for y
You get
1 = 3(1) - 2
1 = 1 , a true statement. So (1,1) IS a solution.
Answer:
(2, 3) is not an ordered pair for y = 3x - 2.
Step-by-step explanation:
(2,3)
y = 3x - 2
3 = 3(2) - 2
3 = 6 - 2
3 = 4
This means that (2, 3) is not an ordered pair for y = 3x - 2.
