Answer:
The term X is a variable that takes the place of any number. ... Similarly 2 multiplied by X results to X plus X which means a number added to itself since multiplication is a repeated addition. So 2X = 2 * X = X + X = 2X.

Answer:
x=30
Step-by-step explanation:
Since both of the acute angles have around or similar degrees, they will be the same. But even without that information we can see that each of the angles look the same. We already know that there are 360° in a circle, making 180° in a semi-circle. We can add 60+60 which will give us 120°. 360-120=240, which dividing that by 2 will give us 120, and if we were figuring out the other 2 would be 120° each.

Answer: x=20
Step-by-step explanation:
If im wrong, sorry
The angles of a triangle add up to 180 degrees.
(3x+5)+(2x+17)+(2x+18)=180
add the ones alike
3x + 2x + 2x=7x
5+17+18=40
so, 7x+40=180
we need to get the variable by itself so we take away 40 first by subtracting it from both sides of the equal sign
7x=140
we take away 7 from x by dividing it- opposite of multiplication is division
x=20
Answer:
x = 20
Step-by-step explanation:
3x+5° + 2x+18° + 2x+17° = 180° (sum of interior angles in a triangle is 180°)
collect like terms
3x + 2x + 2x + 5° + 18° + 17° = 180°
7x + 40° = 180°
solving for x
x = (180 - 40)/7
x = 140/7
x = 20

The scale of map is 1cm : 70km. What is the actual distance between towns that are 5cm apart on the map
Answer: 350km
Step-by-step explanation:
Since we are informed that the scale of map is 1cm : 70km. Therefore, the actual distance between towns that are 5cm apart on the map will be:
= 5 × 70km
= 350km
Therefore, the answer is 350km

Each hour, every person who knows a rumor tells two other people. If one person starts the rumor, then after the first hour, three people know the rumor. The next hour, those three people each tell two more people. After eight hours, how many people will know the rumor? You do not have to include units in your answer. (I've asked this question before but the answer I got was 384 and it was incorrect)
Answer:
64
Step-by-step explanation:
In this problem n is 6 which represents the sixth and final hour of the period. Therefore gn = g6.
g1 = 2 which is the first value in the sequence which corresponds to the first hour where 2 people know the rumor.
r = the common ratio is 2, because each successive hour the people who know the rumor doubles... {2, 4, 8...}.
Substitute into equation: g6 = 2 x 26-1 = 2 x 25 = 2 x 32 = 64 Answer is 64.

A restaurant sells large and small bowls of soup. A 150-ounce pot of soup can make 10 large bowls. A small bowl of soup is 3/5 the size of a large bowl. How many small bowls of soup can be served from a 108 once pot of soup
12 small bowls of soup can be served from a 108 ounce pot of soup
150-ounce pot of soup can make 10 large bowls. Hence:
Number of ounce in each large bowl = (150 / 10) = 15 ounce per bowl
For 108 ounce pot of soup:
Number of bowls = 108 ounce / (15 ounce per bowl) = 7.2 large bowls
1 small bowl = (3/5) large bowl
7.2 large bowl = 7.2 large bowl / (3/5 large bowl per small bowl) = 12 small bowls
Therefore, 12 small bowls of soup can be served from a 108 ounce pot of soup.

Answer:
a = 4, x = 1
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
WX = YZ , that is
a² + 5a = 5a + 16 ( subtract 5a from both sides )
a² = 16 ( take the square root of both sides )
a = ± [tex]\sqrt{16}[/tex] = ± 4
Since a > 0 , then a = 4
Also
XY = WZ , that is
x² + 6x = 4x + 3 ( subtract 4x + 3 from both sides )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Since x > 0 , then x = 1

PLZZZZZ HELPPPP!!!! i'm very confused on what to do !!!! what is the length of the apothem of a regular hexagon with 16cm side lengths round to the nearest tenth
Answer:
A = 4.6 cm
Step-by-step explanation:
Here, we want to find the length of the apothem, given the side lengths
Mathematically, we have this as;
A = s/2 tan (180/n)
where in this case;
s is the length of the sides which is 16 cm
n is the number of sides (since it is hexagon, we have this as 6)
Substituting these values;
A = 16/2 * tan (180/6)
A = 8 * tan 30
A = 4.62
To the nearest tenth, A is 4.6 cm

The area of a triangle is 36 cm square. Give three possible sets of dimensions for the triangle and explain whether or not you can also give the triangles' side length.
Answer:
[tex]Base = 6cm[/tex] and [tex]Height = 12cm[/tex]
[tex]Base = 4cm[/tex] and [tex]Height = 18cm[/tex]
[tex]Base = 9cm[/tex] and [tex]Height = 8cm[/tex]
Step-by-step explanation:
Given
Shape: Triangle
[tex]Area = 36cm^2[/tex]
Solving (a): Three possible dimensions
The area of a triangle is:
[tex]Area = 0.5 * Base * Height[/tex]
Let: [tex]Base = 6cm[/tex]
So, we have:
[tex]36= 0.5 * 6* Height[/tex]
[tex]36= 3* Height[/tex]
Solve for Height
[tex]12 = Height[/tex]
[tex]Height = 12[/tex]
So, a possible dimension is: [tex]Base = 6cm[/tex] and [tex]Height = 12cm[/tex]
Let: [tex]Base = 4cm[/tex]
So, we have:
[tex]36= 0.5 * 4* Height[/tex]
[tex]36= 2* Height[/tex]
Solve for Height
[tex]18 = Height[/tex]
[tex]Height = 18[/tex]
So, a possible dimension is: [tex]Base = 4cm[/tex] and [tex]Height = 18cm[/tex]
Let: [tex]Base = 9cm[/tex]
So, we have:
[tex]36= 0.5 * 9* Height[/tex]
[tex]36= 4.5* Height[/tex]
Solve for Height
[tex]8 = Height[/tex]
[tex]Height = 8[/tex]
So, a possible dimension is: [tex]Base = 9cm[/tex] and [tex]Height = 8cm[/tex]
So, the three possible dimensions are:
[tex]Base = 6cm[/tex] and [tex]Height = 12cm[/tex]
[tex]Base = 4cm[/tex] and [tex]Height = 18cm[/tex]
[tex]Base = 9cm[/tex] and [tex]Height = 8cm[/tex]
Solving (b): Can the side lengths be given
We can only determine the base and the height of the triangle, the third side length can not be determined using the available information

Answer:
C is correct
Step-by-step explanation:
Firstly, we have to solve for x in the solution set of the inequality
We have this as follows;
x + 2 ≥ 6
x ≥ 6-2
x ≥ 4
To graph this, we consider the middle sign which is greater than or equal to
So, the inequality sign has to face the right side
secondly, it has to be shaded on the point 4 due to the fact that it has the ‘equal to’ beneath the single inequality symbol
so, the correct answer here is option C
the linear function g is defined by g(x)=4x. show that g(3) and g(2) have a difference of 4.
Answer:
the answer is D.
Step-by-step explanation:
well, the y-intercept for f(x) is at
as you can see from the slope-intercept form is at 4, and it has an slope of 2/3.
for g(x), well an y-intercept is when x = 0, what is it from that table? well, is at 0,3, so when x = 0, y = 3, so no dice on that one.
c)
whenever an x-intercept occurs, y = 0, for f(x) that's at
what about the x-intercept for g(x)? well, let's check, when is y = 0? aha! at -9, 0, so when y = 0, x = -9, so no dice on that one either.
d)
well, what is the slope of g(x) anyway? well, let's pick two points off the table to get it hmmm the first two let's use,
and from a), using the slope-intercept form, we know f(x) has a slope of 2/3.
well, 2/3 is larger than 1/3, so no dice.
b)
well, you already know.
