Answer:
2
Step-by-step explanation:
4x+3−x=12x−15
Combine 4x and −x to get 3x.
3x+3=12x−15
Subtract 12x from both sides.
3x+3−12x=−15
Combine 3x and −12x to get −9x.
−9x+3=−15
Subtract 3 from both sides.
−9x=−15−3
Subtract 3 from −15 to get −18.
−9x=−18
Divide both sides by −9.
x= –18÷–9
Divide −18 by −9 to get 2.
x=2
What is the traslation rule?
Mapping Rule A mapping rule has the following form (x,y) → (x−7,y+5) and tells you that the x and y coordinates are translated to x−7 and y+5. Translation A translation is an example of a transformation that moves each point of a shape the same distance and in the same direction.
Answer:
(X,Y)
Step-by-step explanation:
depends on the number so if it is (x-7) which is left 7 (y+5) up 5

1/2 x + 2 = x - 2
Multiply both sides by 2
2 × ( 1/2 x + 2 ) = 2 × ( x - 2 )
x + 4 = 2x - 4
Add both sides 4
x + 4 + 4 = 2x - 4 + 4
x + 8 = 2x
Subtract both sides x
x - x + 8 = 2x - x
x = 8A dive ring on the bottom of the pool is 10 feet below the surface of the water. Sabine dives down and brings the ring back to the surface. What integer represents the dive ring's final position with respect to the surface of the water.
The final position of the dive ring with respect to surface of water ls 0.
Representing position using integer :
10 feets below the surface = - 10
To recover the ring, then, Sabine needs to 10 feets below the surface.
The surface the water = sea level position = 0
Since, Sabine takes the ring back to the surface, then the final position of the dive ring will be the sea level.
The final position of the dive ring = 0
We know that we use negative sign in integers to show a value is decreased or dropped and positive sign to show increase or rise.
Given : A dive ring on the bottom of the pool is 10 feet below the surface of the water. Sabine dives down and brings the ring back to the surface.
i.e. Integer represents the distance Sabine dives down = -10 feet (1)
and Integer represents to come back to surface = +10 feet (2)
Now, the final position will be (combine (1) and (2)) :
-10+10=0
Thus, the integer represents the dive ring's final position with respect to the surface of the water = 0
Lesson 14 Introduction
Solutions of Linear Equations
Use What You Know
You've learned how to solve linear equations and how to check your solution. In this
lesson, you'll learn that not every linear equation has just one solution. Take a look
at this problem.
Jason and his friend Amy are arguing. Jason says that a linear equation always has just one
solution. Amy says that some linear equations have more than one solution. Who's right?
Amy asked Jason to explore solutions to the following equation
2x + 1 + x = 3x - 2)+7
Use the math you already know to solve this problem.
Remember that a solution to an equation is a number that makes the equation true.
To check to see if a number is a solution to this equation, replace x with its value.
a. Is 6 a solution to the equation? Show your work
b. Is -2 a solution to the equation? Show your work. 2X
c. Is 0 a solution to the equation? Show your work.
2(-2) + 1 + (-2) = 3(-2 - 2) + 7
-4 + 1 -2 = 3(-4) + 7
-3 - 2 = -12 + 7

1) A jewelry store bought 8 beautiful diamond necklaces. Each necklace cost $9,000. How
much did the jewelry store spend on the necklaces?
Answer:
$72,000
Step-by-step explanation:
Since, a jewelry store bought 8 beautiful diamond necklaces and each cost $9,000 that means;
1 = $9,000
2 = $18,000
3 = $27,000
4 = $36,000
5 = $45,000
6 = $54,000
7 = $63,000
8 = $72,000
or to summarize;
9,000 x 8 = $72,000
As a result, the jewelry store spend $72,000 on the necklaces.

The power, P (watts), of a car engine is proportional to the square of its speed, s (m/s).
When s=35, P=2200.
Work out the power (to 1 DP) when the speed is 40 m/s
Answer:
THE ANSWER!!!!!!!!!!
Step-by-step explanation:
The power, P (watts), of a car engine is proportional to the square of its speed, k%28m%2Fs%29; it means if you have two different powers and speeds, you will have a proportion
P%3Ak%5E2=P%5B1%5D%3Ak%5B1%5D%5E2 or
P%2Fk%5E2=P%5B1%5D%2Fk%5B1%5D%5E2
When given:
k=35, P=2200
Work out the power P%5B1%5D (to 1DP) when the speed is k%5B1%5D=40%28m%2Fs%29
so,
P=2200
k=35
k%5B1%5D=40
and you need P%5B1%5D
2200%2F35%5E2=P%5B1%5D%2F40%5E2
2200%2F1225=P%5B1%5D%2F1600
1.79592=P%5B1%5D%2F1600
1.79592%2A1600=P%5B1%5D
P%5B1%5D=2873.5 watts
4x+8<2x+2
this has quite a bit of points
Answer:
x= −3Step-by-step explanation:
4x+8<2x+2
Subtract 2x from both sides.
4x+8−2x<2
Combine 4x and −2x to get 2x.
2x+8<2
Subtract 8 from both sides.
2x<2−8
Subtract 8 from 2 to get −6.
2x<−6
Divide both sides by 2. Since 2 is positive, the inequality direction remains the same.
x<
2
−6
Divide −6 by 2 to get −3.
x<−3

Help..
Answer:
1/9
Step-by-step explanation:
1) simplify the expression
Group like terms: (2-5-3) + 1/t = 3
Simplify the arithmetic: -6+1/t=3
2) Isolate the t
Multiply to both sides by t: -6+1/t=3t
Expand the parentheses: -6t+1t/t=3t
Simplify the left side: -6t + 1 = 3t
3) Group all t terms on the left side of the equation
Subtract 3t from both sides: -6t+1-3t=3t-3t
Group like terms: -6t-3t+1=3t-3t
Simplify the arithmetic: -9t+1=3t-3t
Simplify the arithmetic: -9t+1=0t
Simplify the right side: -9t+1=0
4. Group all constants on the right side of the equation
Subtract 1 from both sides: -9t+1-1=0-1
Simplify the arithmetic: -9t=0-1
Simplify the arithmetic: -9t=-1
5. Isolate the t
Divide both sides by-9: -9t/-9=-1/-9
Cancel out the negatives: 9t/9=-1/-9
Simplify the fraction:t=-1/-9
Cancel out the negatives: t=1/9

Charlie is shopping for a jacket that he likes. The jacket, regularly priced at $200, is on sale at Clothes Are Us for $150. Jacket World is offering a 25% discount on the same jacket that regularly sells for $190 at that store. Which statements are correct for this situation?
A) Jacket World's price is $150.00
B) Jacket World has the better deal.
C) Clothes Are Us has the better deal.
D) Both stores are offering a 25% discount on the jacket.
E) The difference in the sale prices at the two stores is $7.50.
The correct options are:-
Choice B) Jacket world has the better deal.
Choice D) Both stores are offering a 25% discount on the jacket.
Choice E) The difference in sale prices at the two stores is $7.50
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
25% = 0.25
25% of $190 = 0.25*190 = 47.50
190 - 47.50 = 142.5
This indicates the price at Jacket World is $142.5 instead of $150
Therefore, choice A is false.
Choice B on the other hand is true because $142.50 at Jacket World is a lower price compared to $150 at Clothes Are Us. Jacket World has the better deal.
Because choice B was shown to be true, there's no way choice C can be true as well. Otherwise, we'd have a contradiction. So we can rule out choice C.
Let's find the percentage discount for Clothes Are Us.
The original price is $200 and its sale price is $150. So you save 200-150 = 50 dollars.
Divide that over the original price to find the discount: 50/200 = 0.25 = 25%
Therefore, Clothes Are Us has the same discount percentage as Jacket World. Both have a 25% discount. Choice D is true.

Original price: $60; Markup: 15%; Retail price:
Answer:
Retail Price = $69
Step-by-step explanation:
Original Price = $60
Markup = %15
Retail Price = $60 + (0.15 * $60)
Solve:
We can say that 60 is 100% of 60 or 1 x 60
So the equation is:
1 x 60 + 0.15 x 60 = Retail Price
1.15 x 60 = Retail Price
Retail Price = 69
-Chetan K
Answer:
Original Price is $60
But it is markup 15%
(15x60) / 100 = 9
the 15% of 60 is 9
60 + 9 = 69
Now the retail price is $69
