Answer:
s = -5
Step-by-step explanation:
solve for s
-50 = 10s
divide both sides by 10
-50 / 10 = -5
10s/10 = s
we're left with s = -5
Answer:
solution: s = -5
Step-by-step explanation:
Divide both sides of the equation by the same term

I think the answer is D but I'm not sure. Thanks for helping
Answer:
Yes you are correct, the answer is D
Step-by-step explanation:
the answer is still 420 regardless if you do :
\(42*(3.5+1.3+5.2)\\\)
or
\((42* 3.5)+(42* 1.3)+(42 *5.2)\)

Audrey weaved a blanket. The area of the blanket is 36x2 + 19x - 6 meters
while its length is 9x – 2 meters. Find the expression for the width of the blanket.
Answer:
The area of the floor plan is given by the expression 20x² - 4x - 16
A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are parallel and equal to each other. Also all the angles of a rectangle measure 90 degrees each.
Area of a rectangle = length * breadth
Area of the floor plan = length * breadth
Area of the floor plan = (5x + 4) * (4x - 4)
Area of the floor plan = 20x² - 20x + 16x - 16
Area of the floor plan = 20x² - 4x - 16
The area of the floor plan is given by the expression 20x² - 4x - 16.
Answer:
the expression for the width is 4x + 3
Step-by-step explanation:
Area = base times width. Thus, we divide 9x - 2 into 36x^2 + 19x - 6 to find an expression for the width. Dividing 9x into 36x^2, we get 4x, which tells us that the first term of the quotient starts with 4x: (4x + ? )(9x - 2). Replacing the '?' with 3, we get:
(4x + 3)(9x - 2), which through multiplication becomess
36x^2 + 27x - 8x - 6, or 36x^2 + 19x - 6, which was the original dividend.
Thus the expression for the width is 4x + 3 (in meters).

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
3n-3+10+2n=10 help plz show work
Answer:
n=3/5
Step-by-step explanation:
3n−3+10+2n=10
Step 1: Simplify both sides of the equation.
3n−3+10+2n=10
3n+−3+10+2n=10
(3n+2n)+(−3+10)=10(Combine Like Terms)
5n+7=10
5n+7=10
Step 2: Subtract 7 from both sides.
5n+7−7=10−7
5n=3
Step 3: Divide both sides by 5.
5n /5
= 3 /5
n= 3 /5
Answer:
n=3/5
Step-by-step explanation:
3n-3+10+2n=10 Combine like terms.
5n+7=10 Subtract 7 from both sides.
-7 -7
5n=3 Divide both sides by 5.
/5 /5
n=3/5

===================================================
Explanation:
For me, I find it easier to find the exterior angle first. For any convex polygon, the sum of the exterior angles is 360 degrees. When we talk about regular polygons with n sides, each exterior angle is 360/n degrees. In this case, we have a nonagon with 9 sides. So n = 9 is plugged into 360/n to get 360/9 = 40 as the exterior angle measure
exterior angle = 40
We could stop here since we can see the answer must be choice A. But let's keep going. To get the interior angle, we subtract the result we got from 180
interior angle = 180-(exterior angle) = 180-40 = 140
This is because any adjacent pair of interior and exterior angles must form a straight angle of 180 degrees.
--------------------
side note: you could use the formula \(i = \frac{180(n-2)}{n}\) to find the measure of the interior angle.

Tom's brother saw an advertisement for a special at Muscle Fitness. Membership is $15
monthly, with a mandatory additional $100 charge for equipment maintenance.
Tom saw on television that Platinum Gym was having a grand opening in a few months.
Tom is considering a membership at Platinum Gym. Platinum Gym charges a one-time
registration fee of $60, and membership is $20 a month.
Tom's brother tells him that the Muscle fitness deal is better than the one offered by
Platinum Gym. Is he correct?

months.
(b) Write an expression to represent the membership cost of Platinum Gym for x
months.
(b) At what month will both memberships cost the same overall? Show your work. (2
Answer:
80 - 20 = $60 for reservation and 15 + 20 every month 20 x + 60 + equal muscle fitness
Tom Brady was wrong the cost of line cost the same amount Platinum cost $20 a month and $60 for reservations as the muscle fitness there's no better deal or Worse still cost the same amount
Answer: A) 80 - 20 = $60 for registration and 15 + 5 = $20 every month. 20x + 60= cost of Muscle Fitness B) Tom's brother is wrong. They cost the same amount. Platinum Gym cost's $20 a month and $60 for registration as well as Muscle Fitness. There is no better deal or worse deal. They cost the same amount.

Answer: 1/6
Step-by-step explanation:
First, you have a 1/3 chance of picking 1. Second, you have only 2 and 3 left, which means you have a 1/2 chance of picking a number less than 3. Since you have to multiply these two probabilities, and 1/3x1/2=1/6, the answer is 1/6. Hope this helps!
Directions: Follow the instructions for the following inequalities.
1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9
2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)
3. -2 less than or equal to -2 Subtract 6 from both sides, then 8, and then 2
4. -4 < 8 Divide both sides by -4, then by -2
5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?
Answer:
1. 504 < 1512
2. 12 > 0
3. -2 = -2
4. -1 < 2
Step-by-step explanation:
Given that both sides are being changed by the same amount and sign, the sign never changes. They always have the same value.

Step-by-step explanation:
A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500
