solve for x...................................................................................
Answer:
x = 36°
Step-by-step explanation:
x + 20° + 4x = 200° { exterior angle of a triangle is equal to the sum of two opposite interior angles }
5x = 200° - 20°
5x = 180°
x = 180° / 5
x = 36°

Write an explicit formula for the nth term of this sequence:
6, 11, 16, 21, . . .
1. an=5n+11
2. an=5n+1
3. an=21-5n
4. an=6n+1
Answer:
2)an = 5n + 1
Step-by-step explanation:
This is an arithmetic series.
6 , 11 , 16, 21 ,.....
First term = [tex]a_{1}[/tex] = 6
Common difference = d = second term - first term
= 11 - 6 = 5
nth term = [tex]a_{1}+(n-1)*d[/tex]
= 6 + (n - 1) * 5
= 6 + n * 5 - 1*5
= 6 +5n - 5
= 6 - 5 + 5n
= 1 + 5n
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
Answer:

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.

What is the equation of a line that has slope = -4 and y-intercept is (0, 3)?
Answer: y = -4x + 3
Step-by-step explanation:
y = mx + b
=> y = -4x + b
Find "B":
y = -4x + b
=> 3 = -4(0) + b
=> b = 3
so y = -4x + 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

Annual sales for a fast food restaurant are $650,000 and are increasing at a rate of 4% per year. What is the annual sales after 7 years?
Answer:
Around $855,355.66
Step-by-step explanation:
In these type of problems, you'd use the following equation
[tex]Initial Value * (percentage)^{x}[/tex]
Since the revenue's increasing by 4% every year, you'd plug 104/100 in the percentage box. X is the ammount of times the percentage is applied, so it would be 7, since we're finding the sales after 7 years. Finally, 650000 goes into the initial value and yeah. After calculating, you'll get around $855,355.66

pls help
Answer:
a is the answer as it has 2 constant terms in 3 variables
Step-by-step explanation:
constant means a no. (it doesnt changes)
ex. 2 , 7 etc
variable means a term (generally a letter) which changes, its value will differ.
in the equation you have given both have only 2 variables
have you posted all the options?

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

What’s the answer for this one??
Answer:
It is the second one.
Step-by-step explanation:
a and e are equal because they are mirrored. d and b are equal because they are on the same line and at the same point where the parallel lines go through. b and f are also mirrored. That leaves c and e which don't match.
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%.
