[tex]\Large\boxed{\sf{9x+11}}[/tex]Step-by-step explanation:
Given:
Isolate the term of x from one side of the equation.
Use the distributive property.
DISTRIBUTIVE PROPERTY:
[tex]\Longrightarrow: \sf{A(B+C)=AB+AC}[/tex]
Each term within the parentheses can be multiplied by a factor outside the parentheses.
3(x+1)
3*x=3x
3*1=3
Rewrite the expression down.
3x+3
3x+3+2(3x+4)
Multiply expand.
2(3x+4)
2*3x=6x
2*4=8
6x+8
3x+3+6x+8
Combine like terms.
3x+6x+3+8
Add the numbers from left to right.
3+8=11
3x+6x+11
Add.

Find four consecutive odd integers such that if the sum of the first and fourth is multiplied by three, the result
is 12 less than four times the third.
Answer:
-7, -5, -3, -1
Step-by-step explanation:
Let x be the smallest of the four consecutive odd integers. Then the next three consecutive odd integers are x+2, x+4, and x+6. We have:
[tex]3(x + x + 6) = 4(x + 4) - 12[/tex]
[tex]3(2x + 6) = 4(x + 4) - 12[/tex]
[tex]6x + 18 = 4x + 16 - 12[/tex]
[tex]6x + 18 = 4x + 4[/tex]
[tex]2x = - 14[/tex]
[tex]x = - 7[/tex]
So the four consecutive odd integers are -7, -5, -3, and -1.

Maggie takes three electives: art, Spanish, and creative writing. She calculated the mean absolute deviation of the points she earned throughout the year in each class.
art: mean absolute deviation of 2. 1
Spanish: mean absolute deviation of 0. 8
creative writing: mean absolute deviation of 2. 7
In which elective were her scores the most spread out?
Due to the higher value of the mean absolute deviation, her scores were most spread out in creative writing.
What is the mean absolute deviation of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.The mean absolute deviation represents the average by which the values differ from the mean. Hence, a higher value of the mean absolute deviation means that the data-set is more spread out.In this problem, creative writing has the highest mean absolute deviation, hence, it is the elective in which her scores were most spread out.

55% of what number is 33?
Answer:
18.15
Step-by-step explanation:
55% = 55/100
33 = 33/1
33/1 x 55/100
33 x 55 = 1815
1 x 100 = 100
1815/100 = 18.15
Mike walks mile in half an hour. Which of the following represents his walking speed in miles per
hour?
A. 1/2 mph
B. 1/8 mph
C. 8 mph
D. 3/4 mph
Answer:
Step-by-step explanation:
distance = rate [tex]*[/tex] time
1 (mile) = rate [tex]*[/tex] 0.5 (hours)
[tex]1/0.5 =[/tex] rate
rate = 2 mph...
That however is not answer choice. I'm guessing the number in front of the mile didn't copy over. You can use the same method I did, but just plugging in the actual number instead of 1.
A group of people gathered to watch a baseball game. While talking, they realized that 12 of
them are Boston Red Sox fans, and 18 of them are fans of other teams.
What is the probability that the favorite team of a randomly selected baseball fan is the
Boston Red Sox?
Write your answer as a fraction or whole number.
P(Boston Red Sox) =
Submit
Answer:
P(Boston Red Sox) = 2/5
Step-by-step explanation:
The probability that the favorite team of a randomly selected baseball fan is the Boston Red Sox can be found by dividing the number of Boston Red Sox fans by the total number of fans.
It's given that there are 12 Boston Red Sox fans and 18 other fans. Therefore the total number of fans is 12 + 18 = 30.
If we divide the number of Boston Red Sox fans by the total number of fans, we get 12/30 = 2/5. Finally, we have P(Boston Red Sox) = 2/5.

y=8(x+6)(x-2)
Answer:
y = 8x^2 + 32x - 96.
Step-by-step explanation:
y=8(x+6)(x-2)
= 8(x^2 - 2x + 6x - 12)
= 8(x^2 + 4x - 12)
= 8x^2 + 32x - 96.

Cost price is the total amount paid for the jacket while the selling price is the amount they are sold. The expression for her total earning willbe t(d) = hd - jp
Calculating total earningCost price is the total amount paid for the jacket while the selling price is the amount they are sold.
Total earning = Selling price - Cost price
Find the cost priceIf Dafna makes sport jackets and she is paid d dollars per hour, plus a piece rate of p dollars for each jacket.
Cost price = hd
x is the number of hour
Selling price = jp
total earning = hd - jp
Hence the expression for her total earning willbe t(d) = hd - jp

anyone know how to do #14 and #15?????
Answer:
He Melanie , use SOH CAH TOA to remember the trig functions
Step-by-step explanation:
for 14 they hyp = 22 and we know one angle of 45°, we also know that the triangle has a right angle or 90° and by inspection we can tell that the other angle is also going to be 45° so we know X and Y will be the same length, is why this is a good observation.
Use one of the trig functions with H in it b/c you know Hyp is 22, so,
SOH = Sin(Θ)= Opp / Hyp
Sin(45) = Opp / 22
Sin(45) * 22 = Opp
[tex]\sqrt{2}[/tex] / 2 * 22 = opp
11*[tex]\sqrt{2}[/tex] = opp is the exact answer, if you would like some decimal places, it's 7.7781 units, both X and Y
for 15 we can use SOH again for the bigger triangle. we know the Hyp is 24 and the angle is 30°
Sin(30) = Opp / 24
Sin(30) *24 = Opp
12 = Opp ( Because I know Sin(30) = 1/2 )
Opp is the upright between the two triangles
Use CAH Cos(Θ) = Adj / Hyp
Cos(30) = Adj / 24
Cos(30) * 24 = Adj
[tex]\sqrt{3}[/tex] /2 *24 =Adj
12[tex]\sqrt{3}[/tex] = Adj
Z = 12[tex]\sqrt{3}[/tex] or if you want some decimals 20.7846
Becasue the smaller triangle is also a 45° right triangle we know that the upright and side Y are the same lengths
then
Y = 12
You could use SOH or CAH to find the Hyp but, lets just resort to Pythagoras, and use his formula to find Hyp
Hyp = [tex]\sqrt{12^{2} +12^{2} }[/tex]
Hyp = [tex]\sqrt{288}[/tex]
hyp = 16.97
X = 16.97

Which polynomial represents the sum below?
Answer:
A
Step-by-step explanation:
Shift the bottom trinomial to where like terms match up where it looks like this.
2x²+5x+4
5x²+8x
To make it easier to understand add a placeholder +0 to the trinomial so everything matches up so it looks
like this.
2x²+5x+4
5x²+8x+0
Finally, add like terms and you should end up with this. 7x²+13x+4

Step-by-step explanation:
1) Use this rule: a/b * c = ac/b.
7 * 6/9
2) Simplify 7 * 6 to 42.
42/9
3) Simplify.
14/3
4) Convert to mixed fractin form.
4 2/3
Answer:
The product of 7/9 and 6:
[tex]\\7/9 x 6 \\\\7x6=42\\\\42/9\\4 6/9\\\\4 is the whole number\\6/9 is the fraction that if we remove the 3 from both of us, it gives us the result 2/3\\ The answer is the B \\[/tex]
Step-by-step explanation:
the answer is the B
Because You only had to multiply 6 by 7 and the result, which would be 42 over 9, should be converted to a mixed number, which would be dividing 42 by 9, which is 4, and us over 6, which is four, which is the whole number, and 6 is the numerator and you don't change the nine since it is still the denominator.
Because the 4 is the whole number
And 6/9 is the fraction that if were move the 3 from both of us , it gives us the result is 2/3
So we have 4 2/3
the answer is the B
