Answer:
x = -16
Step-by-step explanation:
3x+11 = 2x - 5
x +11 = -5 (Get x's on one side by substracting 2x from both sides)
x= -16 ( substract 11 from both sides to get the answer
Answer:
[tex]x=-16[/tex]
Step-by-step explanation:
[tex]3x+11=2x-5[/tex]
Subtract 11 from both sides:
[tex]\hookrightarrow[/tex] [tex]3x+11-11=2x-5-11[/tex]
[tex]\hookrightarrow 3x=2x-16[/tex]
Subtract 2x from both sides:
[tex]\hookrightarrow 3x-2x=2x-16-2x[/tex]
[tex]\hookrightarrow x=-16[/tex]

Answer:
The reason why "reposition its product" is the correct answer because Kellogg's is trying to reposition their product in order to make sales. Frosted Flakes was a big time thing for kids, due to the fact that advertisements involved children since Kellogg's target audience were children. Frosted Flakes were pretty much meant for children. Since the product was meant for children, Kellogg's left the people that actually buy the cereal--adults--out of the scene.
Kellogg's releasing advertisements of adults saying how much they loved Frosted Flakes allows viewers to have a thought of going to the store and getting some Frosted Flakes. With the advertisement, they're also trying to target adults because there are a lot of adults in this world, and if they can get adults to buy their product, then their sales will go big. Their goal for the advertisement is to get more sales for the Frosted Flakes product, and they're doing this by having a target audience of adults.

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 48 N acts on a certain object, the acceleration of the object is 6 m\s2 If the acceleration of the object becomes 10 m/s2, what is the force
Answer:
80N
Step-by-step explanation:
F = ma (Newton's second law)
When F=48N, a = 6m/s2
--> m = F/a = 48/6 = 8 (kg)
When a = 10m/s2
--> F = ma = 8 . 10 = 80N

*PLEASE ANSWER , DIFFICULT QUESTION PLEASE* A particular airline offers three free snack options to it's passengers: cookies, chips, and crackers. Along with the snack, passengers are offered two free drink options: soda or water. This is a tree diagram that represents the probability of customers choosing the different snack and drink options. What is the probability of a passenger choosing chips and a soda? a.)25% b.) 33% c.) 50%
The probability that a particular passenger chooses chips and soda as a snack is 0.25 or 25%.
What is probability?In mathematics, probability is considered as the chances a specific situation or event occurs.
For example, you can calculate the probability that it rains tomorrow based on general weather patterns.
For example,
if you throw a die, then the probability of getting 1 is 1/6.
Similarly, the probability of getting all the numbers from 2,3,4,5 and 6, one at a time is 1/6.
How to calculate the probability of two events happenning?
Calculate or identify the probability of each event happening.Multiply the probabilities of the events involved.What is the probability of Z event happnening?Probability that a person choses soda: 0.5Probability that a person choses chips: 0.5Now, let's multiply these probabilities:Now,
Given that:
0.5 x 0.5
= 0.25
= 25% (0.25 x 100)
Hence, the probability of a passenger choosing chips and soda as a snack is 0.25 or 25%.

Nifal earned 9$ for washing two cars .He recived $1 more for the second car.How much was he paid for washing each car?Which two numbers have a sum of 9$?
Answer:
Nifal received $ 4 for washing the first car.
Nifal received $ 5 for washing the second car.
4 and 5 have a sum of 9.
Step-by-step explanation:
The problem can be rewritten as follows: Find the sum of two consecutive entire numbers equal to 9. That is:
[tex]x + y = 9[/tex]
[tex]y = x+1[/tex]
Then, by eliminating y:
[tex]x + (x+1) = 9[/tex]
[tex]2\cdot x + 1 = 9[/tex]
Now, let is clear [tex]x[/tex]:
[tex]2\cdot x = 8[/tex]
[tex]x = 4[/tex]
Nifal received $ 4 for washing the first car.
The earning for the second car is: ([tex]x = 4[/tex])
[tex]y = x +1[/tex]
[tex]y = 4 + 1[/tex]
[tex]y = 5[/tex]
Nifal received $ 5 for washing the second car.
4 and 5 have a sum of 9.
You have 2 positive numbers. One number is one-fifth of the other number. The difference between the two numbers is 228, find the numbers.
Hey there! I'm happy to help!
Let's call these numbers x and y and model the information we have.
x=1/5y
y-x=228 (we see that x is smaller than y in the first equation, so we put it second )
We see that x is equal to 1/5y. We can switch the x in the second equation with 1/5y and solve for y.
y-1/5y=228
4/5y=228
We divide both sides by 4/5.
y=285
We know that x is 1/5 of y, so we divide by 5.
285/5=57
x=57
So, our numbers are 57 and 285.
Have a wonderful day! :D
The 2 positive numbers are 285 and 57 and they have a difference of 228.
EquationAn equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the bigger positive number and y the smaller number. Hence:
y = (1/5)x y - (1/5)x = 0 (1)Also:
x - y = 228 (2)Solving equation 1 and 2 simultaneously gives:
x = 285, y = 57
The 2 positive numbers are 285 and 57 and they have a difference of 228.

C. 57
D. 23
A line segment is also a line but a line with finite length and fixed endpoints. The length of the line segment PT is 23 units. The correct option is D.
What is a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
A line segment is also a line but a line with finite length and fixed endpoints.
Given that point T will lie between points P and B. Therefore, Point T is on the line segment PB. Therefore, it can be said Thus, we can write,
PB = PT + TB
As given the length of PB is 35 units, the length of TB is 12 units,
35 units = PT + 12 units
35 units - 12 units = PT
PT = 23 units
Hence, the length of the line segment PT is 23 units.

It may seem random, but it's heavily biased toward those who participate in politics. It leaves out people who have not contacted the senator. A better method would be to look at voter registration data, and send out surveys to random people on the list.
The hypotenuse of a
right triangle is 10 cm.
One of the side lengths is 8 cm.
What is the length of the other side?
Answer:
6 cm
Step-by-step explanation:
use Pythagorean theorem a² + b² = c²
let c = 10 cm , b = 8 cm
plug in values
a² + 8² = 10²
a² = 10² - 8²
a = [tex]\sqrt{10^2 - 8^2}[/tex]
a = 6 cm
Answer:
6 cm
Step-by-step explanation:
We can use the Pythagorean Theorem to find the length of the missing side.
The Pythagorean Theorem states that the hypotenuse of a right triangle will be [tex]a^2 + b^2[/tex], where a and b are the leg lengths.
Together, we get the formula [tex]a^2 + b^2 = c^2[/tex].
Since we know the hypotenuse (c) and one of the sides (let's say a), we can find the missing side (b) by substituting inside the equation.
[tex]8^2 + b^2 = 10^2\\\\64 + b^2 = 100\\\\b^2 = 100-64\\\\b^2 = 36\\\\b = \sqrt{36}\\\\b=6[/tex]
So the missing side is 6 cm long.

If ABCD is an A4 sheet and BCPO is the square, prove that △OCD is an isosceles triangle. And find the angles marked as 1 to 8 without using a protractor
Answer:
The diagram for the question is missing, but I found an appropriate diagram fo the question:
Proof:
since OC = CD = 297mm Therefore, Δ OCD is an isoscless triangle
∠BCO = 45°
∠BOC = 45°
∠PCO = 45°
∠POC = 45°
∠DOP = 22.5°
∠PDO = 67.5°
∠ADO = 22.5°
∠AOD = 67.5°
Step-by-step explanation:
Given:
AB = CD = 297 mm
AD = BC = 210 mm
BCPO is a square
∴ BC = OP = CP = OB = 210mm
Solving for OC
OCB is a right anlgled triangle
using Pythagoras theorem
(Hypotenuse)² = Sum of square of the other two sides
(OC)² = (OB)² + (BC)²
(OC)² = 210² + 210²
(OC)² = 44100 + 44100
OC = √(88200
OC = 296.98 = 297
OC = 297mm
An isosceless tringle is a triangle that has two equal sides
Therefore for △OCD
CD = OC = 297mm; Hence, △OCD is an isosceless triangle.
The marked angles are not given in the diagram, but I am assuming it is all the angles other than the 90° angles
Since BC = OB = 210mm
∠BCO = ∠BOC
since sum of angles in a triangle = 180°
∠BCO + ∠BOC + 90 = 180
(∠BCO + ∠BOC) = 180 - 90
(∠BCO + ∠BOC) = 90°
since ∠BCO = ∠BOC
∴ ∠BCO = ∠BOC = 90/2 = 45
∴ ∠BCO = 45°
∠BOC = 45°
∠PCO = 45°
∠POC = 45°
For ΔOPD
[tex]Tan\ \theta = \frac{opposite}{adjacent}\\ Tan\ (\angle DOP) = \frac{87}{210} \\(\angle DOP) = Tan^-1(0.414)\\(\angle DOP) = 22.5 ^{\circ}[/tex]
Note that DP = 297 - 210 = 87mm
∠PDO + ∠DOP + 90 = 180
∠PDO + 22.5 + 90 = 180
∠PDO = 180 - 90 - 22.5
∠PDO = 67.5°
∠ADO = 22.5° (alternate to ∠DOP)
∠AOD = 67.5° (Alternate to ∠PDO)

What is the value of x? leave your answer in simplest radical form.
Answer:
2 sqrt(5) =x
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2 + b^2 = c^2
2^2 +4^2 = x^2
4+16 = x^2
20 = x^2
Take the square root of each side
sqrt(20) = sqrt(x^2)
sqrt(4*5) = x
sqrt(4) sqrt(5) =x
