An equation is shown below:
4(2x – 5) = 4
Part A: How many solutions does this equation have? (4 points)
Part B: What are the solutions to this equation? Show your work. (6 points)
Answer:
x = 3
Step-by-step explanation:
A only 1 solution
B
4(2x - 5) = 4 ( divide both sides by 4 )
2x - 5 = 1 ( add 5 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
Answer:
[tex]\boxed{\sf{x=3}}[/tex]Step-by-step explanation:
Isolate it by the term of x from one side of the equation.
Part A. There will be one solution.Part B.4(2x-5)=4First, divide by 4 from both sides.
[tex]\sf{\dfrac{4\left(2x-5\right)}{4}=\dfrac{4}{4}}[/tex]
Then, solve.
4/4=1
Rewrite the problem down.
2x-5=1
Add by 5 from both sides.
[tex]\sf{2x-5+5=1+5}[/tex]
Solve.
1+5=6
2x=6
Divide by 2 from both sides.
2x/2=6/2
Solve.
Divide the numbers from left to right.
6/2=3
x=3
Therefore, the correct answer is x=3.I hope this helps you! Let me know if my answer is wrong or not.

I’ll give brainiest to the best solved An ice cream store sells two different sizes of ice cream cones. The first cone is 4 inches tall and has a 1-inch radius. The second cone is 6 inches tall and has a 1.5-inch radius. What is the ratio of the volume of the smaller cone to the volume of the larger cone?
A.
4 : 9
B.
8 : 27
C.
9 : 4
D.
27 : 8
The volume of the larger cone is about 18.8 cubic inches greater than the volume of the small cone
The volume of a cone is calculated as:
For the small cone, we have the following parameters:
Diameter = 3 inches
Height = 3.5 inches
Diameter = 4.5 inches
Height = 5.1 inches
So, the volume of the large cone is:
Calculate the difference of both volumes
Hence, the volume of the larger cone is about 18.8 cubic inches greater than the volume of the small cone

needed answer
making them as a brainlists
Answer:
x = 16
Step-by-step explanation:
Given:
Number of students = 6Average mark = 15Therefore, total marks = 15 × 6 = 90
To find the value of x, add up the individual marks:
12 + 16 + 14 + 13 + 19 + x = 74 + x
Now equate this to the total number of marks found previously:
74 + x = 90
Solve for x:
⇒ 74 + x - 74 = 90 - 74
⇒ x = 16
Therefore, the value of x is 16.

There are 12 tomato plants for which 75 < h < 85
One of the tomato plants is selected at random.
Find an estimate for the probability that this tomato plant has a height greater than
82.5 cm
The histogram is an illustration of a discrete probability, and the probability that this tomato plant has a height greater than 82.5 cm is 0.40
How to estimate the probability?The histogram is given such that the distribution of the plant heights is:
75 < h ≤ 85
To estimate the probability that this tomato plant has a height greater than 82.5 cm, we make use of the following formula
P(h >82.5) = P(85)
From the histogram, we have:
P(85) = 24/60
Evaluate
P(85) = 0.40
Substitute P(85) = 0.4 in P(h >82.5) = P(85)
P(h >82.5) = 0.40
Hence, the estimated probability is 0.40

The area of a circle is 144 in 2. What is the circumference, in inches? Express you answer in terms of pi.
Answer:
24π inches
Step-by-step explanation:
The area of a circle is denoted by: , where r is the radius. Here, we know that the area is A = , so we can plug this in to find r:
A = [tex]\pi r^{2}[/tex]
[tex]144\pi = \pi r^{2}[/tex]
[tex]r^{2}[/tex] = 144
r = 12
The circumference is denoted by: , where r is the radius. We've found the radius so just plug 12 in for r:
Thus, the circumference is 24π inches.
Hope this helps!
Correct Question :
The area of a circle is 144π in². What is the circumference, in inches? Express your answer in terms of pi.
[tex] \: [/tex]
Step-by-step explanation:
Before finding the circumference of the circle, we have to find the radius of it.
We already know that,
[tex] \longrightarrow \qquad{ \underline {\boxed{ \pmb{ \mathfrak{ \pi r{}^{2} = \: \: Area_{(circle)}}}}}} \: \: \bigstar \\ \\ [/tex]
So, using this formula we'll find the radius and now we'll substitute the given values :
[tex] \longrightarrow \qquad{ \sf{ \pi \times r{}^{2} = \: 144 \pi }} \\ \\[/tex]
Cancelling π from both sides we get :
[tex]\longrightarrow \qquad{ \sf{ \cancel\pi \times r{}^{2} = \: 144 \cancel\pi }} \\ \\[/tex]
[tex]\longrightarrow \qquad{ \sf{ r{}^{2} = \: 144 }} \\ \\ [/tex]
[tex]\longrightarrow \qquad{ \sf{ r{}^{} = \: \sqrt{144} }} \\ \\ [/tex]
[tex]\longrightarrow \qquad{ \sf{ \pmb{ r{}^{} = \: 12 }}} \\ \\ [/tex]
So,
The radius of the circle is 12 inches.[tex] \\ [/tex]
Now we'll find the circumference of the circle :
[tex] \\{ \longrightarrow \qquad{ \underline {\boxed{ \pmb{ \mathfrak{ \: \: Circumference_{(circle)} = 2 \pi r}}}}}} \: \: \bigstar \\ \\ [/tex]
Now, we'll substitute the required values in the formula :
[tex] \\ { \longrightarrow \qquad{ \sf{ \: \: Circumference_{(circle)} = 2 \times \pi \times 12}}} \: \: \\ \\ [/tex]
[tex]{ \longrightarrow \qquad{ \sf{ \: \: Circumference_{(circle)} = 2 \times 12 \pi }}} \: \: \\ \\ [/tex]
[tex]{ \longrightarrow \qquad{ \sf{ \pmb{ \: \: Circumference_{(circle)} = 24 \pi }}}} \: \: \\ \\ [/tex]

What is the right triangle?A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.
It is given that a right triangle has a side length of 16 meters and a hypotenuse of 20 meters.
From a Pythagoras theorem
[tex]b^{2} = c^{2} +a^{2} \\20^{2} = 16^{2} +a^{2}\\20^{2}-16^{2} =a^{2}\\a^{2} = 20^{2}-16^{2} \\[/tex]

Mrs. Smith is saying that the number of termites will double each week, and Mr. Smith is saying that the number of termites will increase by 100% each week.
Let's just look at (2)^x. If we substitute numbers for x, we get:
x = 1 ⇒ 2x = 2 ⇒ 4 x = 3 ⇒ 8 x = 4 ⇒ 16x = 5 ⇒ 32x = 6 ⇒ 64x = 7 ⇒ 128We can see that the output number doubles by 2, or in other words, increases by 100% of its value.
Therefore, Frida is correct in thinking that both Mr. and Mrs. Smith's interpretations are correct.
