155 solve for x
It equals 180 but I don’t know how to solve it
Answers
The solution of x in the given linear equation (x - 13 + 155 = 180) is equal to 38.
To solve the equation (x - 13 + 155 = 180), we need to pursue the following steps.
Step 1. Move all terms to the left:
⇒(x - 13 + 155 - (180)) = 0
Step 2. Add all the numbers jointly, and all the variables
⇒(x - 38) = 0
Step 3. Get rid of parentheses
⇒x - 38 = 0
Step 4. Transfer all terms including x to the left, and all other terms to the right
⇒x = 38
Hence, the required solution of x in the given linear equation (x - 13 + 155 = 180) is 38.

What is factor?A number that divides another number by itself with no residual is known as a factor. In other words, if multiplying two whole numbers results in the creation of a product, the numbers we are multiplying are factors of the product since the product is divisible by them. Division and multiplication are the two ways to discover factors. A number or other mathematical object is factorized or factored in mathematics by expressing it as the product of numerous factors, often smaller or simpler things of the same sort. One factorization of the polynomial x2 - 4 is 3 5, which is also a factorization of the number 15.

In a certain year, 31% of adults in a certain country viewed college education as essential for success. For the following ten-year period, this percentage increased by approximately 2. 6 each year.
The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by __
Answers
The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by the function P(x) = 31 + 2.6x.
What is the percentage function?
To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100. Percentage formula = (Value/Total value) × 100. Example: 2/5 × 100 = 0.4 × 100 = 40 per cent.
The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by the function:
P(x) = 31 + 2.6x
Where P(x) is the percentage of adults who viewed college education as essential for success x years after the first year, and x is the number of years after the first year.
The function shows that the percentage increase by 2.6 every year for x years after the first year, and the initial percentage is 31%.
This function is representing a linear trend since the coefficient of x is constant.
Hence, The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by the function P(x) = 31 + 2.6x.

As an estimation we are told 5 miles is 8 km.
Convert 52 km to miles.
Answers
Answer:
32.5 miles
Step-by-step explanation:
We can convert 52 km to miles using the given estimation.
To convert 52 km to miles, create a proportion where x is how many miles are in 52 km:
[tex]\frac{5}{8}[/tex] = [tex]\frac{x}{52}[/tex]
Cross multiply and solve for x
8x = 260
x = 32.5
So, in 52 km, there are approximately 32.5 miles
52 km is approximately equal to 32.5 miles.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
If we are given the estimation that 5 miles is approximately 8 km, we can use this ratio to convert 52 km to miles.
Let's set up a proportion:
5 miles / 8 km = x miles / 52 km
Cross-multiplying, we get:
5 miles × 52 km = 8 km × x miles
260 miles = 8x
To solve for x, divide both sides of the equation by 8:
260 miles / 8 = x
x ≈ 32.5 miles
Therefore, 52 km is approximately equal to 32.5 miles.

we have to calculate the length of fabaric in yards are used for make one constume .
Let the " x yards " be the fabric length used to make one constume.
Now, total fabric length used to make 8 conatumes = 8x yards
but it will be equals to 52 yards . So, we get a simple linear equation with one variable, i.e

What is meant by histogram?The frequency distribution of a few data points for one variable is represented graphically by a histogram. Heterogeneous "bins" or "range groups" are frequently used in histograms in order to categorize data and count the number of data points that are part of each bin.
Among graphing tools, the histogram is widely used. It is utilized to encapsulate discrete or continuous data that is measured on an interval scale. It is frequently employed as a convenient way to highlight the key characteristics of the data distribution.
As opposed to bar charts, which show categorical variables, histograms visualize quantitative or numerical data. Typically, a histogram's numerical data will be continuous (having infinite values).
Number of people who bought fewer than 30 items

What is the perimeter of the larger triangle?
Answers
Answer:
48 units.
Step-by-step explanation:
Since the triangles are similar (proportional), their dimensions are increased at the same ratio at any point, which means their perimeter too. So the base of the larger triangle is twice as long as the base of the smaller triangle.
The perimeter of the smaller triangle is 10 + 6 + 8 = 24 units.
24 * 2 = 48. Because the ratio of increase is 2:1 from the bigger triangle to the smaller triangle.

A)Mark and Jada share 5 yards of ribbon equally. How much ribbon will each get
B)It takes half of a yard of ribbon to make a bow. How many bows can be made with 5 yards of ribbon?
Answers
Explanation:
Mark and Jada are sharing 5 yards of ribbon equally amongst 2 people, the two of the together. In order to solve the equation, you must divide the number of yards of ribbon by the number of people equally sharing it, which would be 5 divided by 2. 2 can not be multiplied by any non-decimal number to equal 5, so we can put down the number multiplied by 2 that is closest to 5, which would be 2, because 2 x 2 = 4. Subtracting 5 from 4 gives us 1. Since there are no remainders in our answer, the answer will be a decimal. So then we put a decimal in front of the 2, and add a 0 next to the 1 we got by subtracting 4 from 5, turning the 1 into a 10. 2 times 5 equals 10, so add a 5 to your answer and subtract 10 from 10. 10 - 10 = 0, so the answer is 2.5 yards of ribbon. You can check this answer by multiplying the 2.5 yards of ribbon in our answer by the 2 people who are equally sharing it, 2.5 x 2 = 5 yards of ribbon. So we can certainly conclude that Mark and Jada will be sharing 2.5 yards of ribbon.
B) Mark and Jada can make 10 bows with 5 yards of ribbon.
Explanation:
It takes half a yard of ribbon to make a bow, so we will need to find half of 1. 1 divided by 2 equals 0.5, so 0.5 yards of ribbon will be used for each bow. Now we need to find out how many bows can be made with 5 yards of ribbon. 5 divided by 0.5 equals 10, so the answer come out to be 10 bows. You can check your answer by solving 5 divided by 10, which equals 0.5. So we can safely conclude that 10 bows can be made with 5 yards of ribbon.
