Answer:
2.5
Step-by-step explanation:
First, line up all of the number by value, starting from least to gratesest. Then cross one out from each side untill you have only one number left or in, this case, the number between your 2 last numbers.
Answer: + =
Step-by-step explanation:
The equation of a circle is given as :
+ =
Where (a,b) are the coordinate of the center and r is the radius of the circle.
The end point of the diameter is give as (-5, -3 ) and ( -11 , -3 ) , This means that we can find the coordinate of the center by finding the mid point of the end point. The mid point is calculated by :
Mid point = ( , )
= -5
= -11
= -3
= -3
Substituting this values into the formula for finding mid point , we have
Mid point = ( ,
Mid-point = (-8 , -3)
Remember that Radius is half of the diameter , To find the diameter we must find the distance between the two end point using the formula for calculating distance between two points , that is
D =
Substituting the values :
D =
D =
D = 6
Therefore , The diameter i s 6
And since radius is half of the diameter , radius is thus
r = 6/2
r = 3
So , substituting the values gotten into the equation of circle , we have:
+ =
+ =
Answer:
x = k/6 - 50/3
Step-by-step explanation:
K=6x+100
--> Swap sides so that all variable terms are on the left hand side.
6x+100=k
--> Subtract 100 from both sides.
6x=k−100
--> Divide both sides by 6.
6x/6 = k-100/6
--> Dividing by 6 undoes the multiplication by 6.
x = k-100/6
--> Divide k−100 by 6.
Answer : x = k/6 - 50/3
Hope this helps you!
Answer:
x= 15/8
Step-by-step explanation:
we need to solve the equation to find the value of x by adding like terms and then finding the value of x.
You have to distribute the 7 to x and 2 so :
7x+14=2x-1
Add one to both sides (inverse operations)
7x+14=2x-1
+1 +1
7x+15=2x
Cross Cancel by subtracting 7x from both sides
7x+15=2x
-7x -7x
15=-5x
Divide by -5
15/-5= -5/-5
X= -3
