Answer:
x=15
Step-by-step explanation:
1. Solve
4x-6=54
4x-6+6=54+6 <=== Add 6 to both sides
4x=60
4x÷4=60÷4 <=== divide by 4 on both sides
x=15
2. Check
4x15-6=54 <=== Replace x with 15 to check
60-6=54 <=== 4x15 equals 60
54=54 <=== 60-6 equals 54 and 54=54
so it is correct!!

How to solve [tex]2n =\frac{15}{2}[/tex] and [tex]\frac{1}{4} =\frac{n}{5}[/tex] ???
Answer:
[tex]2n=\dfrac{15}{2}[/tex]
Multiply both sides by 2:
[tex]\implies 2 \cdot 2n=2 \cdot \dfrac{15}{2}[/tex]
[tex]\implies 4n=15[/tex]
Divide both sides by 4:
[tex]\implies \dfrac{4n}{4}=\dfrac{15}{4}[/tex]
[tex]\implies n=\dfrac{15}{4}[/tex]
[tex]\dfrac14=\dfrac{n}{5}[/tex]
Multiply both sides by 5:
[tex]\implies 5 \cdot \dfrac14=5 \cdot \dfrac{n}{5}[/tex]
[tex]\implies \dfrac54=n[/tex]
[tex]\implies n=\dfrac54[/tex]
Answer:
Step-by-step explanation:
2n = 15/2
Divide both sides b y 2:
n = 15/2 / 2
= 15/2 * 1/2
= 15/4.
1/4 = n / 5
Multiply both sides by the LCM (20):
20/4 = 20n/5
5 = 4n
n = 5/4.

The triangles ABC and EDC have corresponding sides
The triangles ABC and EDC are similar
How to prove that the triangles ABC and EDC are similar?The given parameters are:
ED = 8, DC = 10, EC = 12, AB = 12
BC = 15 and AC = 21
To determine that the triangles are similar, we simply divide the corresponding sides to determine the scale factor (k).
So, have:
k = AB/ED = BC/DC
This gives
k = 12/8 = 15/10
Evaluate the quotients
k = 1.5 = 1.5
The scale factors are equal
Hence, the triangles ABC and EDC are similar

Express the function graphed on the axes below as a piecewise function.
Answer:
f(x) = {x-3 for x ≤ -1; -3x+14 for x > 5}
Step-by-step explanation:
To write the piecewise function, we can consider the pieces one at a time. For each, we need to define the domain, and the functional relation.
__
Left PieceThe domain is the horizontal extent. It is shown as -∞ to -1, with -1 included.
The relation has a slope (rise/run) of +1, and would intersect the y-axis at -3 if it were extended.
The first piece can be written ...
f(x) = x-3 for x ≤ -1
__
Right PieceThe domain is shown as 5 to ∞, with 5 not included.
The relation is shown as having a slope (rise/run) of (-3)/(1) = -3. If extended, it would intersect the point (5, -1), so we can write the point-slope equation as ...
y -(-1) = -3(x -5)
y = -3x +15 -1 = -3x +14
The second piece can be written ...
f(x) = -3x +14 for x > 5
__
Whole functionPutting these pieces together, we have ...
[tex]\boxed{f(x)=\begin{cases}x-3&\text{for }x\le-1\\-3x+14&\text{for }5 < x\end{cases}}[/tex]
_____
Additional comment
Sometimes it is convenient to write inequalities in number-line order (using < or ≤ symbols). This gives a visual indication of where the variable stands in relation to the limit(s). Perhaps a more conventional way to write the domain for the second piece is, x > 5.

Answer: 170
Step-by-step explanation: Like I answered before: Angle G and Angle H are consecutive angles, meaning they both add up to 180 degrees. Thus, if 10 is the value of Angle G, Angle H must be 170.
Answer:
<CDA = 170⁰
Step-by-step explanation:
<A + <D = 180⁰ { Adjacent Angles of an parallelogram are supplementary}
10⁰ + <D = 180⁰
<D = 180⁰ - 10⁰ = 170⁰
<D = x⁰ = 170⁰ = <CDA

Answer:
80 gummy bears are in 4 servings.
Step-by-step explanation:
2 servings=40 gummy bears
3 servings=60 gummy bears
40+20=60
Add 20 gummy bears for every serving.
5 servings=100 gummy bears
100-20=80 gummy bears are in 4 servings
OR you can also do:
40÷2=20 gummy bears are in each serving
So, 4x20=80 gummy bears are in 4 servings

The area of the triangle RTS will be (8×4) - 1/2 (16+12+10). Then the correct option is A.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
We start by drawing a rectangle around the triangle as shown in the diagram below.
Area of the RST = area of the rectangle - (area of triangle A + area of triangle B + area of triangle C)
[tex]\rm Area\ of\ RST = (8 \times 4) - [(\dfrac{1}{2} \times 8 \times 2) + (\dfrac{1}{2} \times 4 \times 3) + (\dfrac{1}{2} \times 5\times 2)]\\\\\\Area\ of\ RST = (8 \times 4) - \dfrac{1}{2} (16 + 12 + 10)[/tex]
The area of the triangle RTS is (8×4) - 1/2 (16+12+10).

The height of a triangle is 4 times its base. If the triangle has an area of 162 ft2, find the length of the base and the height.
Answer:
base= 9 ft
height= 36 ft
Step-by-step explanation:
Area of triangle= ½ ×base ×height
Let the base and the height of the triangle be b and h ft respectively.
162= ½ ×b ×h
Given that h= 4b,
162= ½ ×b ×4b
162= ½(4b²)
162= 2b²
Divide both sides by 2:
b²= 81
Square root both sides:
b= 9
h= 4b
h= 4(9)
h= 36
Thus, the lengths of the base and height are 9 and 36 ft respectively.

A local phone company offers a cell phone plan that has a fixed cost per month and a cost related to the number of text messages sent. The fixed cost is $20 and each message sent costs 10€. Represent the relation between the total cost and the number of text messages sent, as many different ways as you can.
Answer:

Which of the following numbers CANNOT represent the probability of an event?
A. -0.5
B. 1
C. 0
D. 0.675
-0.5 cannot represent the probability of an event.
Correct option is (A).
What is Probability?This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Arithmetic uses probability to predict how probable certain events are to occur. Probability generally refers to the degree to which something is likely to occur.
As per the given data:
We have to find out that, which of the following numbers CANNOT represent the probability of an event.
Probability of an event = [tex]\frac{Favorable \: Events}{Total \: Number \: of \: Events}[/tex]
Favorable events or total number of events can never be negative, hence the probability of any event cannot be negative.
So from the above reasoning we can say that -0.5 cannot represent the probability of an event.
Hence, -0.5 cannot represent the probability of an event.
