A shipping company charges a $6.50 flat fee for a package, plus a fee based on the weight of the package. The
company charges $1.50 per pound, plus an additional $0.25 for every pound over 6 pounds.
Samuel plans on sending a package that is over 6 pounds. He has $26 to spend on shipping. What is the
maximum number of pounds that this package could be?
1. The cost of shipping 6 pounds is
2. The Maximum number of pounds is
Answer: The cost of shipping 6 pounds is $ 9.00
The maximum number of pounds he can ship is 74 pounds.
Step-by-step explanation:
To find the cost for the first 6 pounds, multiply $1.50 × 6 = $9.00
To find out how much more he can ship, subtract: $26 - $9 = $17
The number of pounds that can be shipped for $0.25 is 17 divided by .25
17/.25 = 68
The total maximum weight is 6 + 68 = 74 pounds.
Check: 6 pounds for $ 9.00 plus 68 pounds for $17.00
The money adds up to $26 and the weight adds up to 74 pounds.

*HELP ME PLEASE* Consider the equation: 3x + 1 – 9 = 3(x + 2) + n.
Give a value of n so that the equation has no solutions.
Explain why you are correct.
Answer:
n = -14
Step-by-step explanation:
Let us try to solve this equation for n;
3x + 1 - 9 = 3(x + 2) + n
3x - 8 = 3x + 6 + n
3x - 3x -8 - 6 = n
-14 = n
The value of n = -14
This value is the value of the equation that will have no solution.
To know if we are correct, let us input this value into the expression
3x + 1 - 9 = 3(x + 2) + n
3x - 8 = 3x + 6 -14
Collect like terms;
3x - 3x = 8 + 6 - 14
0 = 0

solve for x 3(-x-3)+x-3=26
Answer:
[tex]\boxed {x = -19}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]3(-x - 3) + x - 3 = 26[/tex]
-Use Distributive Property:
[tex]3(-x - 3) + x - 3 = 26[/tex]
[tex]3(-x ) - 9 + x - 3 = 26[/tex]
-Combine both [tex]-9[/tex] and [tex]3[/tex]:
[tex]3(-x ) - 9 + x - 3 = 26[/tex]
[tex]3(-x ) - 12 + x = 26[/tex]
-Add [tex]12[/tex] to both sides:
[tex]3(-x ) - 12 + 12 + x = 26 + 12[/tex]
[tex]3(-x) + x = 38[/tex]
-Multiply the [tex]-1[/tex] by [tex]3[/tex]:
[tex]3(-x) + x = 38[/tex]
[tex]-3x + x = 38[/tex]
-Combine both the [tex]-3x[/tex] and [tex]x[/tex]:
[tex]-3x + x = 38[/tex]
[tex]-2x = 38[/tex]
-Divide both sides by [tex]-2[/tex]:
[tex]\frac{-2x}{-2} = \frac{38}{-2}[/tex]
[tex]\boxed {x = -19}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]-19[/tex].
[tex]\bold{Hello!}\\\bold{Your~Answer~Is~Below!}[/tex]
______________________________
[tex]\bold{Solution~Steps:}[/tex]
When we have a problem with parenthesis we must use distributive property:
[tex]3[/tex] × [tex]-x-3[/tex]The [tex]3[/tex] cancels out, leaving [tex]-x[/tex]* [tex]3(-x)-9+x-3=26[/tex]
Subtract [tex]3[/tex] from [tex]-9[/tex]:
[tex]3-(-9)=-12[/tex]* [tex]3(-x)-12+x=26[/tex]
Add [tex]12[/tex] to both sides:
Since [tex]-12[/tex] is negative we do the opposite of what we see, so it cancels out. [tex]-12+12=[/tex] Cancels out[tex]26+12=38[/tex]* [tex]3(-x)+x=38[/tex]
Multiply [tex]3[/tex] and [tex]-1[/tex]:
In this case we have [tex]2[/tex] x's, so we need to get rid of one. We do this by turning [tex](-x)[/tex] into [tex]-1[/tex]. Then we multiply them together: [tex]3[/tex] × [tex]-1=-3[/tex]* [tex]-3x+x=38[/tex]
Combine like terms:
[tex]-3x+x=-2x[/tex]* [tex]-2x=38[/tex]
Divide to get [tex]x[/tex] alone:
Divide by [tex]-2[/tex] on each side by rule of opposites: [tex]-2x[/tex] ÷ [tex]-2=x[/tex] [tex]38[/tex] ÷ [tex]-2=-19[/tex][tex]\boxed{x=-19}[/tex]

Answer: 12.5 square inches
Step-by-step explanation:
The equation for the area of a triangle is A = bh/2
The base and height are both 5, so its 5×5 divided by 2
25/2 = 12.5 or 12 1/2
Area is always square units, so use square inches

Solve the following inequality for m. Write your answer in simplest form.
10m -1 < 4m - 3
Answer:
m < -1/3
Step-by-step explanation:
10m - 1 < 4m - 3
Subtract 4m from both sides;
6m - 1 < -3
Add 1 to both sides;
6m < -2
Divide both sides by 6;
m < -1/3
