can someone please solve this 5+2x=7+3x​

Answers

Answer 1

Simplifying

2x + -7 = 3x + 5

Reorder the terms:

-7 + 2x = 3x + 5

Reorder the terms:

-7 + 2x = 5 + 3x

Solving

-7 + 2x = 5 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-7 + 2x + -3x = 5 + 3x + -3x

Combine like terms: 2x + -3x = -1x

-7 + -1x = 5 + 3x + -3x

Combine like terms: 3x + -3x = 0

-7 + -1x = 5 + 0

-7 + -1x = 5

Add '7' to each side of the equation.

-7 + 7 + -1x = 5 + 7

Combine like terms: -7 + 7 = 0

0 + -1x = 5 + 7

-1x = 5 + 7

Combine like terms: 5 + 7 = 12

-1x = 12

Divide each side by '-1'.

x = -12

Simplifying

x = -12

A total of 2,000 square feet is to be enclosed in two pens, separated by a chain link fence. The outside walls are to be constructed of brick. The brick wall costs $20 per linear foot and the chain link costs $4 per linear foot. Find the dimensions that minimize the construction cost

Answers

Answer:

Dimensions that minimize is; 20 ft x 100 ft

Step-by-step explanation:

Let the width and length be x and y respectively.

We are given area as 2000 Sq.ft.

Thus;

xy = 2000 - - - (eq 1)

We are told that the brick wall costs $20 per linear foot and the chain link costs $4 per linear foot. Thus;

C(x) = 20x + 4y

From eq(1),y = 2000/x

Thus;

C(x) = 20x + 4(2000/x)

C(x) = 20x + 8000/x

To minimize this, we will differentiate and equate to 0.

Thus;

C'(x) = 20 - 8000/x²

Equating to zeeo;

20 - 8000/x² = 0

20 = 8000/x²

20x² = 8000

Divide both sides by 20;

x² = 8000/20

x² = 400

x = √400

x = 20 ft

Putting 20 for x in eq 1,we have;

20y = 2000

y = 2000/20

y = 100 ft

Every bag of peanuts costs $3.55

Answers

Answer:

The constant is that every bag costs $3.55

Step-by-step explanation:

When the bag of peanuts costs $3.55 then Constant of proportionality is 3.55

What is constant of proportionality?

The constant of proportionality is the ratio between two directly proportional quantities

Here,

Every bag of  peanuts costs $3.55

Consider the number of bags =  x

Cost of the peanut bag = y

Therefore

y is directly proportional to x

y = kx

Where k is the constant of proportionality

k = [tex]\frac{y}{x}[/tex]

if the cost of the one bag is $3.55

Then [tex]k=\frac{3.55}{1}[/tex]

k=3.55

Hence, When every bag of peanuts cost constant of proportionality is 3.55

Answers

Answer:

The correct answer is A. That fifty percent is a statistic.

Step-by-step explanation:

Statistics is the science that studies the collection of objective data from reality and its subsequent analysis for the extraction of specific information on the group from which the data were obtained. Thus, statistics obtains different samples (such as opinions, personal characteristics, etc.) of a certain group, and compares their results with the purpose of establishing objective parameters applicable to the entire society.

In this way, the fact that in a survey 50% of the respondents answer in a specific way constitutes a specific statistic regarding that sample, which can in turn be transferred to society as a whole.

The area of a rectangle is a 40 square inches. The width of the rectangle is 4 inches more than the length. What are the dimensions of the rectangle?

Answers

Answer:

I think 10

Step-by-step explanation:

because 4 times 10 is 40 and 4 side so 10 for each side

The dimensions of the rectangle are 4.63 inches and 8.63 inches respectively.

Let the length of the rectangle be L.Let the width of the rectangle be W.

Given the following data:

Area of a rectangle = 40 square inches.

Translating the word problem into an algebraic equation, we have;

[tex]W = L + 4[/tex]

To find the dimensions of the rectangle:

Mathematically, the area of a rectangle is given by the formula;

[tex]Area = LW[/tex]

Substituting the values into the formula, we have;

[tex]40 = L(L+4)\\\\40 =L^2+ 4L\\\\L^2+ 4L -40=0[/tex]

Solving the quadratic equation by using the quadratic formula, we have the following values;

L = 4.63 or −8.63

Length, L = 4.63 inches.

For the width:

[tex]W = L + 4[/tex]

[tex]W = 4.63 + 4[/tex]

W = 8.63 inches

the breadth of a rectangular plot is 20 m less than its lengths find its dimensions if its perimeter is 120​

Answers

Answer:

breadth = 25m

length= 35m

Step-by-step explanation:

perimeter is distance all round a figure

in a rectangle we have two pairs of  opposite but equal lines

breadth = 2x( because of the two breadths in a rectangle) - 20

length = 2x(  because of the two lengths in a rectangle)

perimeter = 2x + 2x - 20

120 = 4x - 20

120 + 20 = 4x

140 = 4x

35 = x

to get the dimensions, we have to divide by 2 as we took both parts of each dimension

breadth = 2x - 20

                     2

             =2(35) - 20

                      2

              = 70 - 20

                      2

              = 50m

                   2

               = 25m

length = 2x

              2

        = 2(35)

              2

        = 70m

              2

           = 35m

In general, how do the slopes of line segments in the image compare with the slopes of corresponding line segments in the preimage? What effect does the scale factor of the dilation have on the slopes, if any?

Answers

Answer:

The slopes of the line segments are the same before and after dilation. The value of the scale factor n does not affect the slopes in the image.

Step-by-step explanation:

Plato simple answer

The slopes of the line are the same before and after dilation. The value of the scale factor n does not affect the slopes in the image.

How does dilation works?

Dilation of a figure will leave its sides get scaled (multiplied) by same number.

Dilation if, is from the center of the rectangle, then distance of all the points of the rectangle from its center will get scaled by that dilation factor.

Slope:

We know that the slope is the ratio of change in y-value and change in x-value.

So, after dilation

m---->m

Length of line:

The length of line =x

so, it's length will become nx.

Answers

Answer:

Find the number of students in each van and in each bus?

13 students can fit in van and 45 students can fit in bus

There were 13 students in each van and 45 students in each bus for both High School A and High School B.

Let's assume that the number of students in each van is "v" and the number of students in each bus is "b".

From the information given, we can form the following equations:

Equation 1: 4v + 2b = 142 (High School A)

Equation 2: 2v + 4b = 206 (High School B)

We can start by multiplying Equation 1 by 2 and Equation 2 by 4 to eliminate the "b" variable:

2 * Equation 1: 8v + 4b = 284

4 * Equation 2: 8v + 16b = 824

Now, we subtract Equation 1 from Equation 2:

(8v + 16b) - (8v + 4b) = 824 - 284

12b = 540

b = 540 / 12

b = 45

Substitute the value of "b" back into Equation 1:

4v + 2(45) = 142

4v + 90 = 142

4v = 142 - 90

4v = 52

v = 52 / 4

v = 13

Therefore, there were 13 students in each van and 45 students in each bus for both High School A and High School B.

Urgent! Line l is parallel to line m. If the measure of <6 is 75o, what is the measure of <1?

Answers

Answer:

m<1 = 105°

Step-by-step explanation:

<6 and <2 are corresponding angles. Therefore:

m<2 = m<6

Since m<6 = 75°, therefore, m<2 = 75°.

m<1 + m<2 = 180° (linear pair angles)

m<1 = 180° - m<2 (substitution property of equality)

m<1 = 180° - 75° (substitution)

m<1 = 105°
