Answer:
x=9
Step-by-step explanation:
First, distribute the negative sign, changing (2x+9) to -2x-9
next, distribute. 10x+−2x+−9=(−3)(15)+(−3)(−4x)
then, combine like the like terms (10x+−2x)+(−9)=12x−45
then you get 8x+−9=12x−45, and you will subtract 12x from both sides, resulting in −4x−9=−45. To get -4x by itself, add 9 to both sides
lastly, divide both sides by -4
x=9
Answer:
x = 9
Step-by-step explanation:
Distribute
10x - (2x + 9) = -3 (15 - 4x)
10 − 2 − 9 = − 3 (15 − 4)
Combine like terms
8 − 9 = − 3 (15 − 4 )
Rearrange terms
8 − 9 = − 3 (− 4 + 15)
Distribute
8 − 9 = 12 − 45
Add 9 to both sides of the equation
8 − 9 + 9 = 12 − 45 + 9

An online auction charges sellers a flat fee of $1.20 and 2% of the amount of the sale. Let A be the amount of the sale in
dollars and C be the charge of the online auction. Explain whether the solutions A = -5 and C=1.1 are viable. (1 point)
O The solutions are not viable because the amount of the sale cannot be negative.
O The solutions are viable because the amount charged is positive.
O The solutions are not viable because the amount charged is not a whole number
O The solutions are viable because the amount of the sale is an integer.
Answer: The solutions are not viable because the amount of the sale cannot be negative.
Step-by-step explanation:
The solution A = -5 is not viable because A represents the amount of sale in dollars and so cannot be a negative number. The minimum amount that a person can make from sales is $0 so anything less than that is not viable.
For instance, if you are selling shoes for $4 each and make no sales in the day, your sales would be $0. It is not possible that your sales would be -$4.
Today Yumaira sold twice as many bags of popcorn at the ball game as she sold last Saturday. In the 2 days she sold a total of 96 bags. Find The number of bags of popcorn sold today and how many popcorn bags were sold on Saturday.
Answer:
32 bags we sold last Saturday, and 64 today.
Step-by-step explanation:
So first, we make a ratio. 2:1, as she sold twice as much. yo could also write it in an equation; 2x+x=96. in both, we see that 3x is equal to 96, and so, x would be equal to 32. to find how many she sold today, multiply that number by 2, to get 64. Hope this helped :)

hope this helps :)
If the triangles below are similar the corresponding angles are proportional, and the corresponding sides are congruent. Option J is correct,
What is the similarity law for triangles?It is defined as the law to prove that two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
Thus, if the triangles below are similar the corresponding angles are proportional, and the corresponding sides are congruent. Option J is correct.

An animal shelter currently has 40 cats in it. Next month they expect the number of cats to increase by 15% over the number this month. Which of the following is the number of cats they expect next month
Answer:
46
Step-by-step explanation:
15% of 40 is 6 so you add 6 to 40
Answer:46
Step-by-step explanation:
15% of 40=?
multiply 15 by 40 and divide by 100
15 * 40 / 100 = 6
add 6 to 40
40+6=46
Therefore, the number of cats that they expect is 46.

You select a card at random. The cards are labeled with the word "Probability" as seen below. Without replacing each card, you choose a second card. P(consonant then vowel) =
Answer:
[tex]P(Consonant\ then\ Vowel) = \frac{14}{55}[/tex]
Step-by-step explanation:
Given
Word: PROBABILITY
[tex]n(Word) = 11[/tex]
Required
Determine P(Consonant then Vowel)
Frist we need to list out the consonants;
Consonants = PRBBLTY
[tex]n(Consonants) = 7[/tex]
Then Vowels
Vowels = OAII
[tex]n(Vowels) = 4[/tex]
[tex]P(Consonant\ then\ Vowel) = P(Consonants)\ and\ P(Vowels)[/tex]
[tex]P(Consonant\ then\ Vowel) = \frac{n(Consonants)}{n(Words)} \ and\ \frac{n(Vowels)}{n(Words) - 1}[/tex]
We used n(words) - 1 for the vowels because it's probability without replacement. So, when the consonant is picked, the length of letters reduced by 1
So, we have:
[tex]P(Consonant\ then\ Vowel) = \frac{7}{11} \ and\ \frac{4}{11 - 1}[/tex]
[tex]P(Consonant\ then\ Vowel) = \frac{7}{11} \ *\ \frac{4}{10}[/tex]
[tex]P(Consonant\ then\ Vowel) = \frac{7}{11} \ *\ \frac{2}{5}[/tex]
[tex]P(Consonant\ then\ Vowel) = \frac{14}{55}[/tex]

Jeffrey earned $65 doing yard work. He bought a pair of jeans for $31.25 and a sweatshirt for $16.50.He set aside the money left from his shopping trip to buy a gift for his cousin. How much money did he set aside for the gift?
Answer:
$17.25
Step-by-step explanation:
Jeffrey earned $65 doing yard work.
He bought a pair of jeans costs = $31.25
and a sweatshirt costs = $16.50
Total amount he spent = 31.25 + 16.50 = $47.75
Now he left with money from his shopping = $65.00 - $47.75
= $17.25
Jeffrey set aside $17.25 for the gift.

Dan deposited $700 in a savings account. At the end of 3 year, he had earned $115.50 in simple interest. What interest rate did he receive? Question 1 options:
Answer:
5.5%
Step-by-step explanation:
The formula for Simple Interest = PRT
Where
Simple Interest = $115.50
P = Principal = $700
R = Interest rate = ??
T = Time in years = 3 years
$115.50 = $700 × R × 3
R = $115.50/$700 × 3
R = $115.50/$2100
R = 0.055
R = Interest rate = 0.055
We Multiply by 100
= 0.055 × 100
= 5.5%

Find the volume of a cone with the radius of 6 height of 8 and length of 10
The volume of the cone with a radius of 6 units, height of 8 units, and length of 10 units is approximately 301.5928 cubic units.
To find the volume of a cone, you can use the formula:
Volume = (1/3) * π * r^2 * h
Where π (pi) is approximately 3.14159, r is the radius of the cone, and h is the height of the cone.
In this case, the radius is given as 6 units, and the height is given as 8 units.
To calculate the volume, substitute these values into the formula:
Volume = (1/3) * 3.14159 * (6 units)^2 * 8 units
Volume = (1/3) * 3.14159 * 36 square units * 8 units
Volume ≈ 301.5928 cubic units
Therefore, the volume of the cone with a radius of 6 units, height of 8 units, and length of 10 units is approximately 301.5928 cubic units.

Answer:

b) 1/15, 0.07
c) 9:1, The ratio means that Jack had spent 9 times more money on shoes than on music, 9/1
Step-by-step explanation:
a) The ratio would be 45:75, simplifying that would be 3/5. Now, 3 divided by 5 is .6, which would be 60%.
b) This ratio would be 5:75, simplifying that would be 1/15. 1 divided by 15 is 0.0666666. Rounding it to the nearest hundreth would get you 0.07
c) The ratio of shoes money and music money would be 9:1. You can find this by making the denominators of each of the fractions the same, so 3/5 multiplied by 3 gets you 9/15. Now, you can easily compare them.
