Answer:
x=4
Step-by-step explanation:
20x-5x=65-5
15x=60
x=60/15
x=4
Answer:
x = 4Step-by-step explanation:
In the question we are given with an equation that is 20x + 5 = 5x + 65 . And we are asked to find the value of x.
Solution :
[tex] \longmapsto \: 20x + 5 = 5x +65[/tex]
Step 1 : Subtracting 5 on both sides :
[tex] \longmapsto \: 20x + \bold{ \cancel{5}} - \bold{ \cancel{5}}= 5x + \bold{65 }- \bold{5}[/tex]
On further calculations, we get :
[tex] \longmapsto \: 20x = 5x + 60[/tex]
Step 2 : Subtracting 60 on both sides :
[tex] \longmapsto \:20x - 60 = 5x + \bold{ \cancel{60}}- \bold{ \cancel{60}}[/tex]
On further calculations, we get :
[tex] \longmapsto \:20x - 60 = 5x[/tex]
Step 3 : Transposing 5x to left hand side and -60 to right hand side :
[tex] \longmapsto \:20x - 5x = 60[/tex]
On further calculations , we get :
[tex] \longmapsto \:15x = 60[/tex]
Step 4 : Divide by 15 on both sides :
[tex] \longmapsto \: \frac{ \cancel{15}x}{ \cancel{15} } = \cancel{ \frac{60}{15} }[/tex]
On further calculations, we get :
[tex] \longmapsto \: \red{ \boxed{x = 4}}[/tex]
Therefore , value of x is 4 .Now, we are verifying our answer by substituting value of x in given equation :
20x + 5 = 5x + 6520 ( 4 ) + 5 = 5 ( 4 ) + 6580 + 5 = 20 + 6585 = 85L.H.S = R.H.SHence, Verified .Therefore , our answer is correct
#Keep LearningWhat is the measure of each angle in the circle?
60°
90°
30°
72°
Answer:
~Lord
The magnitude of the degree in a circle is. there are 5 angels in a circle
measure of each angle:
degree of circle ÷ numbers of angle360° ÷ 5 72°so measure of each angle is 72°
Step-by-step explanation:
As Per Provided Information
Number of sector in given circle is 5
As we know sum of all angles in a circle at centre is 360° .
Since number of sector is given and we are asked to find the measure of each angle in given circle .
[tex] \huge{ \boxed{\sf \: Angle_{(Circle)} = \cfrac{360}{ \: number \: of \: sector}}}[/tex]
Now put the value in above equation and we obtain
[tex] \longrightarrow\sf \: Angle_{(Circle)} = \cfrac{360}{5} \\ \\ \\ \longrightarrow\sf \: Angle_{(Circle)} = \cancel \dfrac{360}{5} \\ \\ \\ \longrightarrow\sf \: Angle_{(Circle)} = {72}^{ \circ} [/tex]
Therefore,

Answer:
r=4.998
Step-by-step explanation:
The equation for volume of a sphere is [tex]V = \frac{4}{3} \pi r^3[/tex].
We can subsatute 523 in for V and then solve for r by multiplying both sides by 3 and then dividing both sides by 4pi. Then, take the cube root of each side and you will get r.

Answer:
y = 120°
Step-by-step explanation:
If AC ≅ AD and BC ≅ BD then the shape of the figure is a kite.
Therefore, ∠D ≅ ∠C
Sum of interior angles in a kite = 360°
⇒ ∠A + ∠B + ∠C + ∠D = 360°
⇒ 120° + ∠B + 100° + 100° = 360°
⇒ ∠B = 40°
Sum of interior angles of a triangle = 180°
⇒ ∠B + ∠BDY + ∠y = 180°
⇒ 40° + 20° + ∠y = 180°
⇒ ∠y = 120°

The answer would be 2x+4+3x+4, 5x+8, and 2(2x+4) +x
Step-by-step explanation:
Step 1. Simplify 2x+4+3x+4 into 5x (combine the x's) +8 (combine the 2 4's)
Step 2. Simplify 2(2x+4)= x into 4x + 8 + x (<-- distribute the 2 to the 2x and 4) and 4x+x would equal 5x meaning 5x + 8.

What is a linear equation?
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
y = mx + b
In which the coefficients are described as follows:
• The coefficient m is the slope of the function, representing the rate of change of the function.
• The coefficient b is the y-intercept of the function, representing the value of y when the function crosses the y-axis(x = 0).
Here the points are(1, -6) and (-2, –8) :
and it is to find the equation of line passing through these points :
Now using slope formula to find the slope of line m :
m = (y₂-y₁)/ (x₂-x₁)
m = (-8+6)/(-2-1)
m = -2/-3
m = 2/3
Therefore, the slope of line that passes through the points (1, -6) and (-2, –8) is 2/3.

I struggled to show the work formatted how I would normally write this problem out, so I'll also talk through how I got the answer.
The first step in long division by hand is to take the number that is furthest to the left and seeing how many times your divisor (26) will go into it.
In this case the digit in the thoudands place (our furthest left) is 8. Obivously 26 does not fit into 8. So our answer will have a 0 in the thousands place and we move one place to the right.
We now have 86. 26 fits into 86 three times and leaves a difference of 8 remaining in the hundreds place, and we move the right again to the tens place.
We again have 86. 26 again fits in three time and leaves a difference of 8. As we move to the right to the ones place we are left with 84.
26 fits into 84 three times, but we have a difference of 6 this time.
We cannot continue as 26 will never fit into our remainder of 6.
We had a 0 in the thousands place, a 3 in the hundreds place, a 3 in the tens place and a 3 in the ones palce with 6 left over.
So the final answer is 333 remainder 6

One of the lamp posts at a bank has a motion detector on it, and the equation (x 15)2 (y−12)2=25 describes the boundary within which motion can be sensed. what is the greatest distance, in feet, a person could be from the lamp and be detected? 5 ft 10 ft 50 ft 125 ft
5 feet is the greatest distance that a person could be from the lamp and be detected.
What is equation of circle?A circle is defined as round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
Since we have given that
The equation is :
[tex](x+15)^2+(y-12)^2=25[/tex]
It is the equation of circle in which center is (h,k) i.e. ( 15,12)
The general equation of circle is given by
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Here, the radius 'r' is given by
[tex]r^2=25[/tex]
[tex]r=\sqrt{25[/tex]
[tex]r=5[/tex]
Here, the greatest distance a person could be from the lamp and be detected is represented by radius i.e. r = 5 feet.
Hence, 5 feet is the greatest distance that a person could be from the lamp and be detected.

Step-by-step explanation:
Keep this in mind :
a² - b² = (a + b)(a - b)In this case,
a = xb = 42So, by factorizing,
x² - 42² = (x + 42)(x - 42)★a²-b²=(a+b)(a-b)
