Sue has 18 sweets Tony also has 18 sweet to give Tony X sweet see you then eat five of her sweets Tony than eat half of his sweets writing expressions for the number sweets Sue and Tony have
Answer:
Sue = 13 - x
(18 + x) / 2
Step-by-step explanation:
Initial Number of sweets:
Tony = 18
Sue = 18
Sue Gives tony x ;
Tony = 18 + x
Sue = 18 - x
Sue eats 5 of her sweets :
Sue = 18 - x - 5
Sue = 13 - x
Tony eats half of his sweets:
(18 + x) / 2

A store manager purchased hoodies for $24.99 apiece. He sells the hoodies for $32. What is the markup percentage?
Given:
A store manager purchased hoodies for $24.99 apiece.
He sells the hoodies for $32.
To find:
The markup percentage.
Solution:
We have,
Cost price (C.P.) = $24.99
Selling price (S.P.) = $32
We know that,
[tex]\text{Markup percentage}=\dfrac{S.P.-C.P.}{C.P.}\times 100[/tex]
[tex]\text{Markup percentage}=\dfrac{32-24.99}{24.99}\times 100[/tex]
[tex]\text{Markup percentage}=\dfrac{7.01}{24.99}\times 100[/tex]
[tex]\text{Markup percentage}=\dfrac{701}{24.99}[/tex]
[tex]\text{Markup percentage}\approx 28.05[/tex]
Therefore, the markup percentage is 28.05%.

Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts and uses 2 of the pieces on gifts.How much ribbon does she use ? Solve this problem any way you choose.
Answer: 6 2/3
Step-by-step explanation:
Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts. This means that each ribbon will be:
= 10/3
= 3 1/3
She then uses 2 of the pieces on gifts. The amount of ribbon that she use will be:
= 3 1/3 × 2
= 10/3 × 2
= 20/3
= 6 2/3

Melissa earns $180 a week selling shoes plus a commission of $10 each pair of shoes she sells. How
many pairs of shoes must she sell to make a minimum of $500 a week?
Step-by-step explanation:
10X+ 180= 500
10X= 500-180
10X= 320. .....divine both sides by 10 to solve for X
X = 32.
check
10(32)+180 = 500
320+180 =500
500 =500...confirmed

3(-4+4)+5n=2n what are the steps for finding n
Answer:
1. Move the variables to one side: 3(-4+4) = -3n
2. Distribute. You will end up with 0 = -3n
3. Divide both sides by -3. n = 0
Step-by-step explanation:
Answer:
n=0
Step-by-step explanation:
3(-4+4)+5n=2n
first distribute
-12+12+5n=2n
combine like terms
5n=2n
subtract 2n on both sides
3n=0
divide by 3 on both sides
n=0/3
which is also equal to
n=0
why are all sequences descrete in math
Answer:
If you collect all the terms of the sequence into a set, that set will always be discrete, because there's only countably many of them, and every interval is uncountable. So you could move outside of natural numbers to real numbers, but then it's no longer a sequence, it's just a function.

Can someone please help me? 3t + 7 = -8
Answer:
Step-by-step explanation:
Look at 3%2At%2B7=%28+-8+%29.
Moved these terms to the left %28 +8+ %29
It becomes 3%2At%2B7%2B _green%28+8+%29=0.
Look at 3%2At%2B_red%28+7+%29%2_red%28+8+%29=0.
Added fractions or integers together
It becomes 3%2At% 2B % 28+15+%29=0.
Look at highlight_red%28+3%2At%2B15+%29=0.
Solved linear equation %28+3%2At%2B15=0+%29 equivalent to 3*t+15 =0
It becomes highlight_green%28+0+%29=0.
Result: 0=0
This is an equation! Solutions: t=-5.
Answer: t= -1/3
Step-by-step explanation:
3t+7=-8
subtract 7 from 7 and 8 (this cancels out the 7)
left with 3t = -1
divide 3 into 3t and -1
the 3 in 3t is canceled out, leaving us with t, therefore t= -1/3
3f^4g^3 x 8fg^4 / (6f^2g^3)^2 how do you do this? I know the answer is 2/3fg but how do you get 0.666... into that fraction form?
9514 1404 393
Answer:
0.666... = 6/9 = 2/3
Step-by-step explanation:
The repeating decimal 0.666... can be turned to a fraction as follows.
Let x represent the value of the number. Then 10x is ...
10x = 10(0.666...) = 6.666...
Subtracting x gives ...
10x -x = 6.666... - 0.666... = 6.000...
9x = 6
Dividing by 9 and simplifying, we have ...
x = 6/9 = 2/3
__
It can be worthwhile to remember that 1/9 = 0.111... repeating.
Then 3/9 = 1/3 = 3(0.111...) = 0.333... repeating
and 6/9 = 2/3 = 6(0.111...) = 0.666... repeating
Most calculators will round the last digit of 2/3 so that it is a 7. So, you may see ...
2 ÷ 3 = 0.6666667 or 0.66666666667
or something similar, depending on your calculator. It is up to you to recognize this as probably a representation of 2/3. Some calculators will display the number as a fraction, so you don't have to guess.
_____
Additional comment
A similar method is used to convert repeating decimals of other lengths to fractions. In general you multiply by 10^n, where n is the number of repeating digits. Then proceed as above: subtract x, divide by the coefficient of x. You will find you are always dividing by a number that has as many 9's as there are repeating digits.

Answer:
x=10, x=-2
Step-by-step explanation:
x^2-5x-3x+15=35
x^2-8x-20=0
Multiply to -20, add to -8: -10, 2
(x-10)(x+2)=0
x=10, x=-2
Answer:
x = −2 or x = 10
Step-by-step explanation:
(x - 3)(x - 5) = 35
x^2 − 8x + 15 = 35
x^2 − 8x + 15 − 35 = 35 − 35
x^2 − 8x − 20 = 0
(x+2)(x−10) = 0
x + 2 = 0 or x − 10 = 0
x = −2 or x = 10

The total revenue from the sale of a popular book is approximated by the rational function, R(x)=1100x^2/x^2 + 4 where x is the number of years since publication and is the total revenue in millions of dollars. Use this function to complete parts a through d.
Answer:
The answer is below
Step-by-step explanation:
The total revenue from the sale of a popular book is approximated by the rational R(x) = 1100x^2/x^2 + 4, where x is the number of years since publication and the total revenue in millions of dollars. Use this function to complete parts a through d. (a) Find the total revenue at the end of the first year. $ million (b) Find the total revenue at the end of the second year. $ million (c) Find the domain of function R. Choose the correct domain below. {x | x is a real number and x greaterthanorequalto 0} {x | x is a real number and x lessthanorequalto 5} {x | x is a real number and x notequalto 2, x notequalto 5} {x | x is a real number and x notequalto 2}
Solution:
Revenue is the total money made from the selling of a product or item.
a) Given the revenue function:
[tex]R(x)=\frac{1100x^2}{x^2+4}[/tex]
At the end of the first year (i.e. x = 1), the venue is given as:
[tex]R(1)=\frac{1100(1)^2}{(1)^2+4} =220\\\\R(1)=\$ 220\ million[/tex]
b) At the end of the second year (i.e. x = 2), the venue is given as:
[tex]R(2)=\frac{1100(2)^2}{(2)^2+4} =220\\\\R(2)=\$ 550\ million[/tex]
c) The domain of the function is the value of the denominator for which the value of the denominator is not zero
x² + 4 ≠ 0
The domain is {x| x is a real number and x ≥ 0}
Peter makes a base monthly salary of $2,500. As a vendor, he must sell $15,000 worth of items per month. He also makes an 18% commission on all sales beyond the monthly quota. If Peter sold $24,600 worth of items this month, what is his total salary for the month including base salary and commission to the nearest dollar?
Answer:
Monthly salary= $4,228
Step-by-step explanation:
Giving the following information:
Fixed salary= $2,500
Sales commission= 10%
Sales= $24,600
To calculate the monthly salary, we need to use the following formula:
Monthly salary= fixed income + commission
Commission= (24,600 - 15,000)*0.18
Commission= $1,728
Monthly salary= 2,500 + 1,728
Monthly salary= $4,228
