hello I hope you are doing well . i have a question lease could you answer it with the step by step explication thanks
this is the equation:
-5x+12-7x=-3(5x+8)
thanks
Answer: X = -12
Step-by-step explanation:
-5x+12-7x=-3(5x+8)
To solve this, first open the bracket.
-5x+12-7x= -15x - 24
Then, collect like terms
-5x + 15x - 7x= -24 - 12
3x = -36
x = -36/3
x = -12
A total of 250 people were surveyed about whether or not each person carries a cell phone. The results are shown below in the relative frequency table. Which statement is correct
Answer:
180 people
Step-by-step explanation:
None of them logically make sense. A is wrong because it is a higher amount of people who carry a cell phone than not. B and C is wrong because not 100% of people they interviewed carry a cell phone so D is the correct answer

The midpoint of AB is M (5,-2). If the coordinates of A are (6,-5), what are the
coordinates of B?
Answer:
(4, 1)
Step-by-step explanation:
To find the second point, first, we must look at how far apart the midpoint and point A are from each other
As seen in picrel, the midpoint is 3 units up and 1 unit left from point A.
We will repeat these units diagonally to make a linear line to find the next point.
3 units up and 1 unit left from the midpoint is (4, 1) which is point B.
For future problems related to finding the second point with only the midpoint and the first point, refer to step 1.

angle C and angle D are a linear pair. angle C is four times larger than angle D. What is the measure of angle C?
By using the fact that the angles form a linear pair, we will see that the measure of angle C is 144 degrees.
How to determine the measures of angles C and D?
Well, we know that these are a linear pair, which means that the angles are supplementary, thus, their measures add up to 180°.
So we can write:
C + D = 180°
Now, we also know that C is four times larger than D, so we can write:
C = 4*D
Replacing that in the equation above we get:
4*D + D = 180°
5*D = 180°
D = 180°/5 = 36°
Then we know that the value of D is 36°, and C is 4 times that, so:
C = 4*36° = 144°
The measure of angle C is 144 degrees.

If f(x) = 3x + 4(x + 1) + 2 then f (4x) =?
Answer:
3×+4(×+2 then f (4×)=21
The expression for f(4x) is 28x + 6. When you evaluate the function f at 4x, you obtain 28 times x + 6. For every value of x, you can plug it into the equation 28x + 6 to get f(4x).
To find the expression for f(4x), we substitute 4x for every occurrence of x in the original function f(x).
Given f(x) = 3x + 4(x + 1) + 2, we have to replace every x with 4x:
f(4x) = 3(4x) + 4(4x + 1) + 2
Now, simplify the expression:
f(4x) = 12x + 4(4x + 1) + 2
f(4x) = 12x + 16x + 4 + 2
f(4x) = 28x + 6
Therefore, the expression for f(4x) is 28x + 6.
This means that when you evaluate the function f at 4x, you get 28 times the value of x plus 6. So, for any given value of x, you can plug it into the expression 28x + 6 to get the corresponding value of f(4x).

What is the solution to this inequality?
7x + 25<=11
Answer:
Step-by-step explanation:
smplifying
7x + 11 = 25
Reorder the terms:
11 + 7x = 25
Solving
11 + 7x = 25
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11' to each side of the equation.
11 + -11 + 7x = 25 + -11
Combine like terms: 11 + -11 = 0
0 + 7x = 25 + -11
7x = 25 + -11
Combine like terms: 25 + -11 = 14
7x = 14
Divide each side by '7'.
x = 2
Simplifying
x = 2

New Year’s Eve is a public holiday in places such as Latvia, the Philippines, and San Marino. It is a holiday for banks in countries such as Bangladesh, Brunei, Paraguay, and Japan (New Year’s Eve is also a government holiday in Japan).
New Year’s Eve is not a nationwide public holiday in countries such as Australia, Canada, the United Kingdom and the United States, but some businesses close early, schools are usually closed, and many people may have half a day off work. Those wishing to travel via public transport may need to check with the local transport authorities on public transport schedules for New Year’s Eve.
Background
New Year's Eve is the last day of the year and the day before New Year’s Day, which marks the start of a new year according to the Gregorian calendar. Pope Gregory XIII introduced the Gregorian calendar in 1582. It was adopted immediately in some areas of Europe but it was not used in various countries until even centuries later. For example, the United Kingdom and the United States started observing the Gregorian calendar in 1752, in which 11 days were dropped.
New Year’s Eve festivities can be traced back to celebrations in Europe that date back before Christianity spread. When many inhabitants in Europe were converted to Christianity, these festivals were merged with Christian beliefs and in time came to mark holidays such as the New Year’s Eve and New Year celebrations.
It is important to note that not all cultures follow the Gregorian calendar in observing New Year’s Eve and New Year’s Day. For example the New Year in the Hindu, Chinese, Coptic, Jewish, Islamic calendars differ to that of the Gregorian calendar.
Symbols
New Year’s Eve and New Year’s Day are symbolized in various ways across the world. Midnight between New Year’s Eve and New Year’s Day is often marked by fireworks and fire crackers. Many people drink and toast with champagne or other sparkling wine.

identify the population being studied and the sample chosen. the heights of 4 out of the 36 pepper plants at mr. lonardo's greenhouse.
The sample = 4 pepper plants
The population = 36 pepper plants
We have to identify the sample and the population from the instance that heights of 4 out of 36 pepper plants are chosen.
Statistical studies are carried out on populations. So here there may be a study related to the heights of the pepper plants.
Sometimes, when the population is very large, studies are carried out on the samples taken from the population which gives not the exact but an approximately same result.
Hence in this case, the sample is the 4 plants chosen from the population of 36 plants at Mr. Lonardo's greenhouse.
Population: Population is the entire and broader group considered for collecting data on a statistical study.
Sample: Sample is the specific, comparatively small group selected from the population from which the data used for study is collected.

Answer:
[tex]c > 0\\t>0\\c+t\geq 60[/tex]
[tex]6c+4t\leq300[/tex]
Step-by-step explanation:
Given that:
[tex]c[/tex] represents the number of cucumber plants
[tex]t[/tex] represents the number of tomato plants
Now, as per the question statement, we can write the inequalities.
The students need to plant some of each plants and at least 60 plants.
i.e.
[tex]c > 0\\t>0\\c+t\geq 60[/tex]
Area required to plant each cucumber plant = 6 sq ft
Area required to plant each tomato plant = 4 sq ft
Area required to plant [tex]c[/tex] cucumber plants = 6[tex]c[/tex] sq ft
Area required to plant [tex]t[/tex] tomato plants = 4[tex]t[/tex] sq ft
Total area is at the maximum 300 square feet
[tex]6c+4t\leq300[/tex]
Therefore, the inequalities to represent the situation are:
[tex]c > 0\\t>0\\c+t\geq 60[/tex]

Bill deposits $3,000 into an account that pays simple interest at a rate of 3% per year. How much interest will he be paid in the first 4 years?
Answer:
The interest he will be paid in the first 4 years is $360
Step-by-step explanation:
The rule of the simple interest is I = Prt, where
P is the initial depositr is the rate in decimalt is the time∵ Bill deposits $3,000 into an account
∴ P = 3000
∵ The account pays simple interest at a rate of 3% per year
∴ r = 3% = 3 ÷ 100 = 0.03
∵ The time is 4 years
∴ t = 4
→ Substitute these values in the rule above
∵ I = 3000(0.03)(4)
∴ I = 360 dollars
∴ The interest he will be paid in the first 4 years is $360

What is the equation of the line that is horizontal and passes through point (−7.8, 2.9)? Answer: __________
Answer:
y = 2.9
Step-by-step explanation:
Horizontal lines have the same y-values for any x-value, so if the line passes through the point (-7.8, 2.9) it must have the same y-value of 2.9 for every other x-value, hence y = 2.9
