3x−x+3−9=6
i cant solve this
Answer:
3x - x + 3 - 9 = 6
3x - x + 3 = 6 +9
2x +3 = 15
2x = 15 - 3
2x = 12
x= 12/2
x= 6
Rules - When the side changes , sign changes .for ex (-9) on changing side (from left to right ) becomes plus 9
Help me I don't know how to find the percent of discount to the nearest percent
Find the percent of discount to the nearest percent.
skateboard: regular price, $24
sale price, $15.50
help. PLEASE.
Answer:8.5
Step-by-step explanation:
Answer:
step one
find the difference between marked price and the selling price, which is 24-15.50=8.5
step two apply the formula which is, difference divided by marked or original price and then multiple by 100
eg (8.5÷24) × 100= 35.4
so now round off to the nearest percent that's 35%
(WORTH 20 POINTS) Please help I don't know how to do this
In your own words, what do the terms sales tax and discount mean? Is a 5 percent sales tax a percent of increase or decrease? What about a 15 percent discount?
lol help-
Answer:
Sales tax is an increase in the price of the item while a discount is the decrease of the price. A 5% sales tax is an increase since your paying an extra 5% of the item price. 15% discount is a decrease since your now only paying 85% of the original price. Hope that helps
Answer: In layman's terms, that means if the original price of something you sell was $100, but you offer a 50% discount, then the taxable price is $50. Sale Price = original price – (% of discount * original price)
Sales Tax = Sales Tax rate * Sale Price.
Sales Tax = 0.05 * $17.21 = $0.8605 = $0.86. How do I add 5% to a number?
Divide the number you wish to add 5% to by 100.
Multiply this new number by 5.
Add the product of the multiplication to your original number.

Ms. McGuirk wants to know if she built her son's new sandbox with a perfect right angle or not? The shorter sides are 15 feet and 8 feet what should the measure of the 3rd side be to make it a perfect right angle?
Answer:
17 feet
Step-by-step explanation:
A right angle has 3 sides: the adjacent, the opposite and the hypotenuse.
The hypotenuse is the largest side of the right angle
The shorter sides are 15 feet and 8 feet which should represent opposite and adjacent sides respectively
Opposite = 15 feet
Adjacent = 8 feet
Hypotenuse = x feet
Using Pythagoras theorem to solve
Hypotenuse ² = opposite ² + adjacent ²
x² = 15² + 8²
x² = 225 + 64
x² = 289
Find the square root of both sides
√x² = √289
x = 17 feet
The 3rd side is 17 feet

Before a renovation a movie theater had 117 seats after the renovation theater had 173 what is the approximate percentage increase of the number of seats in the theater if necessary round to the nearest 10th in percentage
Answer:
47.86%
Step-by-step explanation:
Total number of seats in a movie theater Before a renovation = 117
Total number of seats in a movie theater after a renovation = 173
We need to find the percentage increase of the number of seats. It can be calcualted as :
[tex]\%=\dfrac{\text{|final number-initial number|}}{\text{initial number}}\times 100\\\\=\dfrac{173-117}{117}\times 100\\\\=47.86\%[/tex]
So, the increase in percentage is 47.86%.

Calculate the volume of both containers.
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius and h the height )
[tex]V_{A}[/tex] = π × 10² × 11 = 1100π ft³
[tex]V_{B}[/tex] = π × 7² × 19 = 931π ft³
Subtract volume of B from volume of A to find quantity left in A
quantity left in A = 1100π - 931π = 169π ft³
To calculate the percentage left in A after B has been filled
[tex]\frac{left}{full}[/tex] × 100%
= [tex]\frac{169\pi }{1100\pi }[/tex] × 100%
= [tex]\frac{169}{1100}[/tex] × 100%
= 15.4% ( to the nearest tenth )

An audio books club charges an initial joining fee of $20.00. The cost per audio book is $15.00. The graph shows the cost of belonging to the club as a function of audio books purchased. How will the graph change if the cost per audio book goes up by $1.00?
(The new function is shown by the dotted line.)
Answer:
The graph will change by simply having an increased slope of 16 instead of 15.
Step-by-step explanation:
For this problem, we will consider the initial case as stated by the problem where the joining fee is $20 and each book is $15. Let x represent the number of books that we have purchased. Then, we can write the following function to represent the cost of this club.
f(x) = 15x + 20
Note, if x = 0, meaning we have no books, then
f(0) = 15(0) + 20
f(0) = 0 + 20
f(0) = 20
Which is the cost of our joining fee. If x = 1, meaning we have 1 book, then
f(1) = 15(1) + 20
f(1) = 15 + 20
f(1) = 35
Which is the cost of our joining fee and 1 book, which matches our graphed function.
Now, let's consider that the cost of the book is $16 instead of $15 ("the cost per audio book goes up by $1.00"). Then we can modify the slope of our function to reflect this change giving us the new function:
g(x) = 16x + 20
In this new function, our slope increased from 15 to 16, to account for the increase in cost, but our initial 20 remained the same.
So the graph will change by simply having an increased slope of 16 instead of 15.
Cheers.
Answer:
The new function will have a steeper slope, so...
Step-by-step explanation:
Le: t x ----> the number of audio books purchased
y ---->the cost of belonging to the club in dollars
case 1 (Originally) :
y = 15x + 20
case 2 ( the cost per audio book goes up by $1.00) :
y= (15+1)x+ 20
y = 16x + 20
The slope of the new function is greater than the slope of the original function
The new function will have a steeper slope:
16 $/ audio book > 15 $/audio book
The ratio of solid beads to clear beads in a vase is 820. Select all the correct statements that tell if the operations will give an equivalent ratio.
A) Add 2 solid and 2 clear beads.
B) Subtract 8 solid and 6 clear beads.
C) Multiply the number of solid and clear beads by 2.
D) Divide the number of solid and clear beads by 4.
E) Multiply the number of solid and clear beads by 18.
Answer:
C, D and E
Step-by-step explanation:
Given
Represent solid beads with S and clear beads with C
So:
[tex]S:C = 8:20[/tex]
Required
Select operations that give an equivalent ratio
First, we need to get the unit ratio
[tex]S:C = 8:20[/tex]
Divide through by 4
[tex]S:C = 2:5[/tex] -- This means that, after any operation. The equivalent ratio must be 2: 5
Option A: Add 2 to S and 2 to C
[tex]S:C = 8:20[/tex]
Perform the operation
[tex]S:C = 8 + 2 : 20 + 2[/tex]
[tex]S:C = 10 : 22[/tex]
Divide through by 2
[tex]S:C = 5:11[/tex]
Option B: Subtract 8 from S and 6 from C
[tex]S:C = 8:20[/tex]
Perform the operation
[tex]S:C = 8 - 8 : 20 - 6[/tex]
[tex]S:C = 0 : 14[/tex]
Option C: Multiply S and C by 2
[tex]S:C = 8:20[/tex]
Perform the operation
[tex]S:C = 8*2:20*2[/tex]
[tex]S:C = 16:40[/tex]
Divide through by 8
[tex]S:C = 2:5[/tex]
Option D: Divide S and C by 4
[tex]S:C = 8:20[/tex]
Perform the operation
[tex]S:C = 8/2:20/4[/tex]
[tex]S:C = 2:5[/tex]
Option E: Multiply S and C by 18
[tex]S:C = 8:20[/tex]
Perform the operation
[tex]S:C = 8*18:20*18[/tex]
[tex]S:C = 144:360[/tex]
Divide through by 72
[tex]S:C = 144/72:360/72[/tex]
[tex]S:C = 2:5[/tex]
From the calculations above, options C, D and E gave an equivalent of 2:5.
