What is a linear equation?

A linear equation is one in which the maximum power of the variable is one. Mathematically, an equation of the type axe + b = 0 or axe + by + c = 0, where a, b, and c are real integers and x and y are variables of maximum power one.

We know that,

Students under age 15 who prefer walk/bike + Students age 15 and above who prefer walk/bike = total of column

So, Students under age 15 who prefer walk/bike

   = total of column - Students age 15 and above who prefer walk/bike

   = 152 - 65

   = 87.

Now, total of rows = total of columns

       Row 1 + Row 2 = 360

      Row 1 = 360 - Row 2

                 =360-195

                 = 165.

Now, Students under age 15 who prefer bus + Students under age 15 who prefer walk/bike + Students under age 15 who prefer car = Row table

So, Students under age 15 who prefer bus

    = 165 - 60 - 87

    = 18.

Similarly,

Students under age 15 who prefer bus + Students 15 and above who prefer bus  = column total

So, Students 15 and above who prefer bus  = 110 - 18

                                                                         = 92.

Finally, students age 15 and above take a car to school

           = 195 - 92 - 65

           = 38.

Step-by-step explanation: try to solve for a by itself by multiplying it on both sides that give you 3 = 1*a. that simply just means that a is equal to 3, so you substitute three to the a variable that will give 3/3 that's equal to 1.

By trigonometric formulas, there are two solution sets for the trigonometric equation 2 · cos β = - √(3 · cos β) + sin β + 2 · cos β: β₁ ≈ 0.402π + 2π · k, β₂ = - 0.402π - 2π · k, where k is an integer.

In this problem we find the case of a trigonometric equation, whose roots must be found by algebra properties and trigonometric formulas. First, write the complete expression:

2 · cos β = - √(3 · cos β) + sin β + 2 · cos β

Second, simplify the expression by algebra properties:

√(3 · cos β) = sin β

Third, square both sides and simplify the expression:

3 · cos β = sin² β

3 · cos β = 1 - cos² β

cos² β + 3 · cos β - 1

Fourth, factor the resulting expression:

(cos β - 0.303) · (cos β + 3.303)

Fifth, determine the set of solutions:

cos β = 0.303

β₁ ≈ 0.402π + 2π · k, β₂ = - 0.402π - 2π · k, where k is an integer.

As a result, the circle's precise size is (529/4)π³  square centimetres.

A circle is a closed, two-dimensional shape where every point in the surface is equally spaced from a central point. The line of mirror symmetry is formed by all lines that traverse the circle. Additionally, every point has circular symmetry around the centre.

The circumference of a circle is given by the formula:

C = 2πr

where r is the radius of the circle. We can rearrange this formula to solve for the radius:

r = C / 2π

When we substitute the circumference's specified number, we obtain:

r = (23r) / (2π)

Simplifying:

r = (23/2)π

Now that we know the radius, we can use the formula for the area of a circle:

A = πr²

Substituting the value we found for the radius, we get:

A = π[(23/2)π]²

Simplifying:

A = π(529/4)π²

A = (529/4)π³

Therefore, the exact area of the circle is (529/4)π³ square cm.

Here we have the image of some triangles, and we want to find the value of the interior angle x in the left triangle.

What you need to remember here is that the sum of the interior angles of any triangle is always equal to 180°.

Then, for the left triangle, we can write:

30° + 80° + x° = 180°

Use the rule, “add 8” to find the cost of 6 T-shirts. The cost of the T-shirt is $48.

One of the four fundamental operations in mathematics is addition, along with subtraction, multiplication, and division.

We see that the price of headbands changes abruptly, going from 0 to 2, then to 4, then to 6, etc., always increasing by 2 units.

The “add 8” rule applies to the price of T-shirts because each one costs $8.

In order to determine the cost of six headbands, we then perform the following calculations:

8 + 8 + 8 + 8 + 8 + 8 = 6 x 8 = $48

If each hamburger she makes has a mass of about 0. 125 kg she can make a maximum of 16 hamburgers with the amount of ground beef she has.

To determine how many hamburgers Kendra can make, we need to divide the total mass of ground beef by the mass of each hamburger:

Total mass of ground beef = 0.652 kg + 0.545 kg + 0.824 kg = 2.021 kg

Number of hamburgers = Total mass of ground beef / Mass of each hamburger

Number of hamburgers = 2.021 kg / 0.125 kg = 16.168

Since Kendra can only make whole hamburgers, she can make a maximum of 16 hamburgers with the amount of ground beef she has.

Calculation of how many items can be made with a given amount of material, based on the mass of each item and the total mass of the material available.

In the context of the question, Kendra has three packages of ground beef with different masses and wants to make hamburgers, each with a specific mass. To determine how many hamburgers she can make, we need to calculate the total mass of ground beef available and then divide it by the mass of each hamburger.

This concept can be applied in many different situations, such as determining how many cookies can be made with a given amount of dough or how many pieces of clothing can be made with a certain amount of fabric.

Answer:

Your answer is <PBD = 56

Step-by-step explanation:

That red square indicate that its a right triangle meaning that <PBH is 90°

Those two angle <PBD and <DBH are complementary angle meaning that those two angle add up to 90°

So,

<PBD + <DBH = 90°

(3k + 65°) + 34 = 90

3k + 65 + 34 = 90

3k = -9

k = -3

Plug in k = -3 in <PBD to solve for the measure angle.

<PBD = (3k + 65°) ; k = -3

<PBD = 3(-3) + 65

<PBD = -9 + 65

<PBD = 56

Angles in a quadrilateral add to 360°. So

[tex]60+80+120+x=360[/tex]   (where [tex]x[/tex] is the fourth angle)

The first term is 9, the second term is 17, and the third term is 25.

The 100th term of an arithmetic sequence is given by the formula:

Tn = a + (n-1)d

Where Tn is the nth term, a is the first term, n is the number of terms, and d is the common difference.

In this case, the 100th term is 783, the common difference is 8, and the first term is 9.

Plugging in the values into the formula, we get:

783 = 9 + (100-1)8

Solving for the first term, we get:

783 = 9 + 792

783 = 801

a = 9

The second term, Q2, can be found by adding the common difference to the first term:

Q2 = a + d

Q2 = 9 + 8

Q2 = 17

The third term, az, can be found by adding the common difference to the second term:

az = Q2 + d

az = 17 + 8

az = 25

the first term is 9, the second term is 17, and the third term is 25.

If Alan and Robert worked together, it would take them 6.857 hours to move the inventory from the truck to the shelves

If Robert can move the inventory from his store from the truck to the shelves in 12 hours and Alan can do the same job in 16 hours, then we can find the time it would take for them to do the job together by using the formula for combined work rate:

1/t = 1/12 + 1/16

Multiplying both sides of the equation by 48t gives us:

48 = 4t + 3t

The number of squares wide needed is 7 squares and the number that can be used to replace A is 0.1 km.

Grid squares are a way to represent two-dimensional space using a grid of squares, with each square representing a unit of length.

Grid squares are often used in various fields, such as computer graphics, geographic information systems, and mathematics, to represent and manipulate two-dimensional data.

Here we have

The table shows the distance traveled in a time period

The maximum time is shown in a table = 35 minutes

Let 1 unit = 5 minutes

Number of squares used to represent 35 minutes = 35/5 = 7

Therefore, the number of squares wide needs = 7 blocks

Given that the grid is 20 squares tall

The maximum distance in a table = 1.8 km  

Let's take the total distance = 2 km

The number of squares along length = 2 km/20 = 0.1
