x=20 ornaments
Kay has to sell 20 ornaments to get a profit of $40.00.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Cost for the table = $30
Cost for each ornament = $2.50
Selling price of each ornament = $6.00
Profit = Revenue - Expense
Let x be the number of ornaments sold to get a profit of $40.00.
Revenue = 6x
Expense = 30 + 2.5x
6x - (30 + 2.5x) = 40
3.5x - 30 = 40
3.5x = 70
x = 20
Hence selling 20 ornaments would give Kay a profit of $40.00.

A line passed through the points (1, 2) and (3,-4).
Determine the equation of that line in slope intercept
form.
The slope of the line is m = -3
The y-intercept is (0,5)
The equation of the line in the slope-intercept form is y = 5-3x
solve for u
-4+ u =-2
u=?
Answer:
u = 2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex]-4 + u = -2[/tex] [tex]u - 4 = -2[/tex]Step 2: Add 4 to both sides.
[tex]u - 4 + 4 = -2 + 4[/tex] [tex]u = 2[/tex]Therefore, u = 2.
the percentage of measurements that are below the 88th percentile is

Find the value of x.
Answer:
x = 8
Step-by-step explanation:
All angles of a triangle must add up to 180 degrees.
So 8x + 7 + 6x + 8x - 3 = 180
Combine like terms
22x + 4 = 180
Subtract 4
22x = 176
Divide
22x ÷ 22 = 176 ÷ 22 = x = 8
We can make sure this is correct by plugging in 8 for all x terms.
8(8) + 7 + 6(8) + 8(8) -3
64 + 7 + 48 + 64 - 3 = 180.
X = 8
Hope this helps.

What is the rate of change for the equation y = 2x + 100?
+
The rate of change is
h
Answer:
Rate of change = 2
Step-by-step explanation:
The rate of change is equivalent to the slope of the line !
A line is written:
y=mx+b
"m" is the slope, and "b" is the y-intercept !
The line you gave was "y=2x+100"
The slope, or "m," in your equation, would be 2 !
Which ordered pair is a solution of the equation y=x-2
A. (3,1)
B. (1,3)
C. (-1,3)
D. (3,-1)
Answer:
A. (3 , 1)
Step-by-step explanation:
Note the placement of x and y for points:
(x , y)
Plug in the corresponding numbers for the corresponding variables:
(x , y) = (3 , 1)
y = x - 2
(1) = (3) - 2
1 = 3 - 2
1 = 1 (True).
A. (3 , 1) is your answer.
