Answer:
x=2 (work is correct)x=4x=44x=4x=any numberimpossible; no such numberStep-by-step explanation:
1. The equation is ...
3x +5 = 11
3x = 11 -5 = 6
x = 6/3 = 2 . . . . matches the work shown
__
2. The equation is ...
(x +2)·5 = 30
x +2 = 30/5 = 6
x = 6 -2 = 4
__
3. The equation is ...
(x/2) +2 = 24 . . . . matches the work shown
x/2 = 24 -2 = 22
x = 22·2 = 44
__
4. The equation is ...
2x +8 = x +12
2x = x + 12 -8 = x +4
2x -x = x -x +4
x = 4
__
5. The equation is ...
2x +4 -x -3 = x +1
x +1 = x +1 . . . . . true for any value of x
__
6. The equation is ...
(3x +6) -2x = x +3
x +6 = x +3 . . . . . not true for any number
_____
Additional comment
The work shown is correct. You find x by writing and solving an appropriate equation. To solve the equation, undo the steps that are done to x. Undo addition by adding the opposite. Undo multiplication by diving by the multiplier. It often helps to collect terms before you start the "undo" steps.
For x on both sides of the equation (as in problems 4–6), you can subtract the term with the lowest coefficient. (Of course, you must subtract it from both sides of the equation.) In problem 5, if you do that, you get 1=1, which is true for any value of x. In problem 6, if you do that, you get 6=3, a false equation, indicating no value of x will make it true.
The Answer is:
1. x=2
2. x=4
3. x=44
4. x=4
5. x=any number
6. no such number
hope it helped bye <3

Mr. Jaxon tips 25% of the dinner bill before tax. The expression 0.25(102−x) models the tip amount for a total bill of $102, where x is the dollar amount of tax. Mr. Jaxon tips $23.50. How much is the tax?
Answers
Answer: 1.02
Step-by-step explanation:because it is
The tax amount for the dinner bill can be calculated with the given expression.The tax amount for the dinner bill given by Mr jaxon is $8.
Given-
Total Total amount of the bill dinner is $102.
Tips given by Mr. Jaxon [tex]t[/tex] percent is 25 percent of the dinner bill before tax.
The expression for the tip amount [tex]t[/tex] can be model as,
[tex]t=0.25(102-x)[/tex]
Here [tex]x[/tex] is the tax amount.
Put the value of the tip in the above expression we get,
[tex]23.5=0.25(102-x)[/tex]
Divide by 0.25 both side, we get,
[tex]\dfrac{23.5}{0.25} =(102-x)[/tex]
[tex]94 =(102-x)[/tex]
Rewrite the equation for the [tex]x,[/tex]
[tex]x=102-94[/tex]
[tex]x=8[/tex]
Thus, the tax amount for the dinner bill given by Mr jaxon is $8.

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.
Is the function representing the weekly paycheck amount of Salesman A a proportional relationship? Use complete sentences to explain your reasoning.

Answers
Answer:
See explanations below
Step-by-step explanation:
Given the quadrilateral ABCD
A(3,0),B(-4,4),C(-7,0) and D(-3,-5)
The sides of the quadrilateral are AB, BC, CD and AD
The midpoint coordinate of the line is expressed as;
X = x1+x2/2
Y = y1+y2/2
Given A(3,0),B(-4,4)
Midpoint of AB = (3-4/2, 0+4/2)
midpoint of AB = (-0.5, 2)
Given B(-4, 4),C(-7, 0)
Midpoint of BC = (-4-7/2, 4+0/2)
midpoint of BC = (-11/2, 4/2)
Midpoint of BC = (-5.5, 2)
Given C(-7, 0) D(-3,-5)
Midpoint of CD = (-7-3/2, 0-5/2)
midpoint of CD = (-10/2, -5/2)
Midpoint of CD = (-5, -2.5)
Given A(3,0),D(-3, -5)
Midpoint of AD = (3-3/2, 0-5/2)
midpoint of AD = (0/2, -5/2)
Midpoint of AD = (0, -2.5)
