The solution of the given linera equation in one variable 12=2-k is at k = 10.
According to the given question.
We have a linear equation in one variable 12 = 2 - k.
As we know that, linear equation in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
Therefore, the solution of the linear equation in one variable 12 = 2 - k is given by
12 = 2 - k
⇒ 12 - 2 = -k (subtracting 2 from both the sides)
⇒ 10 = -k
⇒ k = 10
Hence, the solution of the given linera equation in one variable 12=2-k is at k = 10.

Step-by-step explanation:
that is just to be read from the chart.
a)
we see Kiev has 1° C.
Oslo has 2° C.
what is the difference ? 2 - 1 = 1°
b)
don't get confused.
the chart says temperatures at midday.
6 hours later IS 6pm.
the temperature in Kiev raises during that time from 1° up by 6°.
that means the temperature there is then 1 + 6 = 7° C at 6 pm.
Answer:
a. 9 °C
b. 7°C
Step-by-step explanation:
a. Difference, Rome and Oslo
→Rome: 11°C
→Oslo: 2°C
11°C- 2°C = 9°C
b. Kiev
The chart shows temperatures at midday (12pm). After 6 hours it's 6 pm.
→Kiev 1°C
→Temperature will rise 6°C
1°C + 6 °C = 7°C
At 6pm, the temperature in Kiev will be 7°C.

Answer:96
Step-by-step explanation:
whats the formula for speed distance and time?
We know the formulae:
[tex]\text{Speed} = \dfrac{\text{Distance}}{\text{Time}}[/tex]
Let us solve an example to understand the concept better.
Example:Question: Find the speed of a car which travelled 12 km in 2 hours.
Solution: We know the following
Car travelled (Distance): 12 kmTime travelled: 2 hoursSubstitute the information provided into the speed formula:
[tex]\implies \text{Speed} = \dfrac{\text{Distance}}{\text{Time}}[/tex]
[tex]\implies \text{Speed} = \dfrac{\text{12 km}}{\text{2 hours}} = \boxed{6 \ \text{km/hour}}[/tex]
Therefore, the speed of the car is 6 kilometers per hour.
Concept #2: Distance FormulaeFrom the previous concept, we had:
[tex]\text{Speed} = \dfrac{\text{Distance}}{\text{Time}}[/tex]
Finding the distance formula through step-by step work:
Let Speed = S, Distance = D, and Time = T.
[tex]\implies \text{S} = \dfrac{\text{D}}{\text{T}}[/tex]
Multiply "t" on both sides:
[tex]\implies \text{S} \times \text{T}= \dfrac{\text{D}}{\text{T}} \times \text{T}[/tex]
[tex]\implies \text{S} \times \text{T}={\text{D}[/tex]
From the above work, we can say that Distance = Speed × Time.
Let us solve an example to understand the concept better.
Example:Question: A train travelled from point A at a speed of 16 km/h in 2 hours to reach point B. Find the distance (Point A - Point B) travelled by the train.
Solution: We know the following
Speed of train: 16 km/hTime taken to travel from A to B: 2 hoursSubstitute the information provided into the distance formula:
[tex]\implies \text{Distance = Speed} \times \text{Time}[/tex]
[tex]\implies \text{Distance = 16 km/h} \times \text{2 hours}[/tex]
⇒ Distance = 16 km × 2 = 32 km
Therefore, the train travelled 32 km to reach point B.
Concept #3: Time FormulaeFrom the previous concept, we had:
[tex]\text{Distance = Speed} \times \text{Time}[/tex]
Finding the time formula through step-by step work:
Let distance = D, speed = S, and time = T
[tex]\implies \text{D = S} \times \text{T}[/tex]
Dividing "S" both sides:
[tex]\implies \dfrac{\text{D}}{\text{S}} = \dfrac{\text{S} \times \text{T}}{\text{S}}[/tex]
[tex]\implies \dfrac{\text{D}}{\text{S}} = \text{T}[/tex]
From the above work, we can say that Distance/Speed = Time.
Let us solve an example to understand the concept better.
Example:Question: A plane traveled 200 km at a speed of 100 km/h. How much time did it take to travel 200 km?
Solution: We know the following
Distance travelled by the plane: 200 kmSpeed of plane: 100 km/hSubstitute the information provided into the time formula:
[tex]\implies \text{Time} = \dfrac{\text{Distance}}{\text{Speed}}[/tex]
[tex]\implies \text{Time} = \dfrac{\text{200 km}}{\text{100 km/h}} = \dfrac{\text{2 km}}{\text{1 km/h}} = \boxed{\text{2 hours}}[/tex]
Therefore, it took 2 hours to travel 200 km at a speed of 100 km/h.

Find the center and the radius of each circle. x²+(y+1)²=5
The equation of the circle x^2 + (y + 1)^2 = 5 has a radius of √5 and a center located at (0 , -1).
The standard form of the equation of circle is given by
(x - h)^2 + (y - k)^2 = r^2

A dog is chasing a squirrel and the dog is running 45 miles per hour, how long does it takes the dog if he catches the squirrel in 3 miles?
Answer:
4 minutes.
Step-by-step explanation:
45 miles in 60 minutes
3 miles in x minutes
3 x 60 divided by 45 = 4
To check yourself, 45 divided by 3 gives you 15 sets of 3 minute segments. 15 x 4 = 60 minutes or 1 hour.
Find the coordinates of point P on →AB that partitions the segment into the given ratio AP to PB .
b. A(0,0), B(-15,0), 2 to 3
The line segment AB is divided at point P, which has coordinates P(0,-7.5)
A line segment is a section of a line that connects two locations to create a straight line or we can say that is connects two distinct points together to form a single line. It is extendable to either side.
Given are,
A line segment AB with coordinates of A(0,0 ) and B(-15,0) respectively
Two minor line segments, AP and PB, are created from the line segment AB by the provided point P
We must determine the dividing point's coordinates, or P.
We'll apply the formula provided,
The coordinates of the point P are given by = ([tex]\frac{x1+x2}{2}[/tex],[tex]\frac{y1+y2}{2}[/tex] )
Now, x1 = 0, x2 = 0, y1 = -15, y2 = 0
Putting values in the formula, we get
([tex]\frac{0+0}{2}[/tex], [tex]\frac{0-15}{2}[/tex])
(0,-7.5)
Hence, the point P which partitions the line segment AB have coordinates as P(0,-7.5)

Determine whether the given measures define 0,1,2 , or infinitely many triangles. Justify your answers.
a=25, b=21, m
We can form an endless number of triangles when you are given two sides and no measurement of angle i.e a = 25 , b = 21
For Example -
We can chose the value of angle from 0-360 degrees with side length a = 25 and b =21, how many different triangles are possible to create?
Create one of the triangles with a protractor having the side lengths a = 25 m and b = 21 m and angle 12° and third side can be adjusted to your preferred length. You have built a triangle.
Similarly by changing the length of the third side and measure of the angle we will get an entirely new triangle.
It's important to notice that you choose the side lengths and angle. This suggests that you might make a different decision. By employing the same angles, you were able to make an infinite number of different triangles.
Therefore, with simply the measurements of one angle and a side length, we can create an endless number of triangles.

A bicycle has tires with a diameter of 26 inches. Find the radius and circumference of a tire. Round to the nearest hundredth, if necessary.
A circle is a curve sketched out by a point moving in a plane. The radius and the circumference of the circle are 13 inches and 81.6814 inches, respectively.
What is a circle?A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the center.
Given that diameter of the circle is 26 inches. Therefore, the radius and the circumference of the circle can be written as,
Diameter of circle = 2 × (Radius of the circle)
Radius of the circle= Diameter of circle / 2
Radius of the circle = 26 inches / 2
Radius of the circle = 13 inches
Circumference of circle = 2 × π × (Radius of the circle)
= 2 × π × 13 inches
= 26π inches
= 81.6814 inches
Hence, the radius and the circumference of the circle are 13 inches and 81.6814 inches, respectively.
