Answer:
[tex]\Longrightarrow:\boxed{\sf{x=3}}[/tex]
Step-by-step explanation:
Isolate the term of x, from one side of the equation.
2(x+10)=x+23Use the distributive property.
Distributive property:
⇒ A(B+C)=AB+AC
2(x+10)
2*x=2x
2*10=20
2x+20=x+23
First, subtract by 20 from both sides.
2x+20-20=x+23-20
Solve.
Subtract the numbers from left to right.
23-20=3
2x=x+3
Then, you subtract by x from both sides.
2x-x=x+3-x
Solve.
[tex]\Longrightarrow: \boxed{\sf{x=3}}[/tex]
Therefore, the correct answer is x=3.Answer:
x = 3Option A is the correct answer .Step-by-step explanation:
In this question we're given with an equation that is 2(x + 10) = x + 23 and we are asked to find the value of x .
Solution : -
[tex] \longmapsto \: 2(x + 10) = x + 23[/tex]
Step 1 : Solving the parenthesis on left hand side :
[tex]\longmapsto \:2x + 20 = x + 23[/tex]
Step 2 : Subtracting 20 on both sides :
[tex]\longmapsto \:2x + \bold{ \cancel{20}} - \bold{ \cancel{20} }= x + \bold{23 - 20}[/tex]
On further calculations , we get :
[tex]\longmapsto \:2x =x + 3[/tex]
Step 3 : Subtracting x on both sides :
[tex]\longmapsto \:2x - x = \bold{ \cancel{x} }+ 3 - \bold{ \cancel{x}}[/tex]
On further calculations, we get :
[tex]\longmapsto \: \red {\boxed{{x = 3}}}[/tex]
Therefore, value of x is 3 .Now , we're verifying our answer by substituting the value of x in given equation :
2(x + 10) = x + 232 ( 3 + 10 ) = 3 + 232 ( 13 ) = 2626 = 26L.H.S = R.H.SHence, Verified .Therefore, our answer is correct.

We know the sum of the interior angles is 720° for a hexagon.
Finding x
2(90)° + 2(5x + 10)° + 136° + 134° = 720°180° + 10x° + 20° + 270° = 720°10x° + 470° = 720°10x° = 250°x = 25Finding m∠ABC
∠ABC = 5x + 10∠ABC = 5(25) + 10∠ABC = 125 + 10∠ABC = 135°The manager of a juice bar polled 56 random customers to get feedback on a new smoothie. the results are shown in the frequency table. a 4-column table with 3 rows. the first column has no label with entries adult, child, total. the second column is labeled like with entries 23, 18, 41. the third column is labeled dislike with entries 6, 9, 15. the fourth column is labeled total with entries 29, 27, 56. complete the statements using the table. the number of children who disliked the smoothie is . the total number of children is . the conditional relative frequency that a customer disliked the new smoothie, given that the person is a child is approximately .
The number of children who disliked the smoothie is 9, total children is 27, and conditional relative frequency is 33%
What is a conditional relative frequency?It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell to total frequency.
From the data given in the table:
The number of children who disliked the smoothie = 9
The total number of children = 27
To find the conditional relative frequency that a customer disliked the new smoothie(if the person is a child)
It is the ratio of total number of children who disliked the smoothie to total number of children, mathematically:
= 9/27
= 0.3333
= 0.3333×100
= 33.33 ≈ 33%
Thus, the number of children who disliked the smoothie is 9, total children is 27, and conditional relative frequency is 33%

A lab is monitoring the population of mice in a sample. Scientists noticed the number of mice triples every week. If there were initially 4 mice in the sample, how many mice will there be after 6 weeks?
A. 324 Mice
B. 972 Mice
C. 2916 Mice
D. 8748 Mice
C. 2916 Mice
Step-by-step explanation:
4 x 3^6 = 2916
Because as the mice increases, you triple that amount, instead of tripling 4 & multiplying by 6.
So, you're doing this instead:
4 x 3 = 12 (1 wk)
12 x 3 = 36 (2 wk)
36 x 3 =108 (3 wk)
108 x 3 = 324 (4 wk)
324 x 3 = 972 (5 wk)
972 x 3 = 2916 (6 wk)

A movie premiere had a full house of 350 film buffs. The price of the tickets was $6 for adults and $4 for underage. The income from ticket sales was $1,600. What is the number of adult's, x, who attended?
A 80
B 140
C 100
D 250
Answer:
C
Step-by-step explanation:
let x be number of adults and y the number of underage , then
x + y = 350 → (1)
6x + 4y = 1600 → (2)
multiplying (1) by - 4 and adding to (2) will eliminate y
- 4x - 4y = - 1400 → (3)
add (2) and (3) term by term to eliminate y
(6x - 4x) + (4y - 4y) = 1600 - 1400
2x + 0 = 200
2x = 200 ( divide both sides by 2 )
x = 100
the number of adults who attended is 100

A number line from negative 3 to 3 in increments of 1. An open circle is at negative 5 and a bold line starts at negative 5 and is pointing to the left.
The solutions are all the points strictly larger than 5, to represent this, we draw an open circle at x = 5, and a bold line that points to the right.
How to represent the inequality?
Here we have the inequality:
–3(2x – 5) < 5(2 – x)
First, we need to isolate x in one side of the inequality, we will get:
-6x + 15 < 10 - 5x
15 - 10 < -5x + 6x
5 < x
Then the solutions are all the points strictly larger than 5, to represent this, we draw an open circle at x = 5, and a bold line that points to the right.

The dot plot with the least number of sites has the least frequency
The dot plot has the least number of sites is the Shield Darter
How to determine the dot plot?To determine the dot plot with the least number of sites, we simply calculate the total frequency of each dot plot
So, we have:
Shield Darter = 3 + 1 + 4 + 2 + 3 + 1 + 1
Shield Darter = 15
Calico Crayfish = 1 + 1 + 3 + 4 + 1 + 2 + 4 + 2
Calico Crayfish = 18
Zebra Mussel = 1 + 3 + 2 + 5 + 1 + 1 + 2 + 3 + 2
Zebra Mussel = 20
Blue back Herring = 3 + 3 + 2 + 1 + 3 + 1 + 4
Blue back Herring = 17
From the computation above, the least frequency is
Shield Darter = 15
Hence, the dot plot has the least number of sites is the Shield Darter

__
The statement that is not true about this construction is ...
B) When you're finished, you have a line that bisects your segment
_____
Additional comment
The construction effectively creates an arc of a circle, then creates the perpendicular bisector of the chord of that arc. The center of the circular arc is the vertex of the angle being bisected. The constructed perpendicular bisector of the chord also bisects the angle. (The chord is never actually drawn, and the "circular arc" may be two short arcs across the rays of the angle being bisected.)

Triangle ABC has angles A; B; C is proportional to 1; 2; 3 then the measure of the angles of the triangle is
Step-by-step explanation:
Let the angle of triangle be x , so each angle will be 1x , 2x , 3x respectively.
We know that sum of all angles in triangle is 180°
So ,
1x + 2x + 3x = 180°
6x = 180°
x = 30°
Therefore , each angle would be 30° , 60° , 90° respectively.
