Mathematical expressions can be used to depict situations or issues, and algebra is the field of mathematics that does this. For a mathematical expression to have meaning, it needs to include variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division. Algebra is used in every area of mathematics, including coordinate geometry, calculus, and trigonometry. A straightforward algebraic expression is 2x + 4 = 8.

Given that : first day of ticket sales the school sold 14 adult tickets and 5 student tickets for a total of $140. The school took in $190 on the second day by selling 10 adult tickets and 10 student tickets.

Let the price for adult ticket x and for student ticket y

we have ,

14x + 5y =140.....(i)

10x  + 10y = 190....(ii)

10 x + 10y = 190

x + y = 19

y = 19-x .....(iii)

put the value of y in equation i

14x + 5(19-x) = 140

14x + 95 - 5x = 140

9x = 45

x = 5

Now put value of x in equation iii

y = 19 - 5

y = 14

Answer:

Step-by-step explanation:

(a+6)(a-3)

2a + 3b = 7
-> 3(2a + 3b) = 21
6x + 10y = 40
-> (6x+10y)/2 = 20

Therefore, 6a + 9b = 21 ; 3x + 5y = 20.

The value of 6a + 9b is 21 and the value of 3x + 5y is 20

An equation is a combination of different variables, in which two mathematical expressions are equal to each other.

The given equations are,

2a + 3b = 7                  (1)

and 6x + 10y = 40        (2)

To find the value of 6a + 9b,

Multiply equation (1) with 3,

3(2a + 3b) = 7 x 3

6a + 9b = 21

To find the vale of 3x + 5y,

Divide equation (2) by 2,

1/2(6x + 10y) = 40/2

3x + 5y = 20

The required values are 21 and 20.

Answer:

-1, 1, 3

Step-by-step explanation:

Let x equal the first odd integer.

The three consecutive odd integers would be represented by x, then x+2, then x+4.

So 3x + 2(x + 4) = 4(x + 2) - 1

Solve for x

3x + 2x + 8 = 4x + 8 -1

5x + 8 = 4x + 7

x = -1

Explanation below:

Step-by-step explanation:

So basically x is the diameter - so is the radius times by 2

The radius is the length from the center of the circle to the edge which in this case is 7.9 + 8.9 = 16.8

So from this we have worked out the radius which is 16.8

But x is the diameter so we have to times 16.8 by 2 which gives 33.6

For every mile the car is driven, the cost increases by 0.52 units.

Consider a line that passes through the origin at a distance 'a' from the Y-axis and has a slope of m. In this situation, the distance an is the definition of the line's y-intercept. At this moment, the line will cross the y-axis (0, a). The equation for the line will then be y = mx + a. The same goes for a line that crosses the X-axis at a position b from the origin and has a slope of m. (b,0). The distance b is the line's x-intercept. The equation for the line will be y = m* (x-b)

Given, the equation that relates cost of renting and miles driven is
y = 0.52 x + 186
Therefore, for a car travelling one mile, cost is y₁ = 0.52*1 + 186 = 186.52
For a car travelling two miles, cost is y₂ = (0.52*2) + 186 = 187.04
Thus, for every next mile the cost increases by = y₂ - y₁ = 187.04 - 186.52 = 0.52 units

Step-by-step explanation:

It is to be noted that the height of the bread is 5 centimeters. The hint given is in the information about the surface area. See the explanation below.

In this case, the surface area of bread is the total sum of the area of the base and perimeter. The surface area of the bread is given below.

That is:

A = 2 x b + p x H,

Where b is the area of the base,  p is the perimeter of the base and h is the height.

Recall that it is stated that 50% of the surface area of the bread is the crust.

The implication is that the surface area of both sides of the base is equivalent to the surface area of its perimeter.

That is:

2 x b = p x h

We can compute the perimeter of the bread as:

P = 4 x length
p = 4 x 10
p = 40cm

The area of the base is:

b = 10 x 10
b = 100cm²

Substituting the values in the above formula,
2 x 100 = 40 x h
200 = 40h
h = 200/40

h= 5cm.

Hence the height of the bread is 5cm.

Jeweler needs 144 inches of silver chain to make the necklaces and 108 inches of silver chain to make the bracelets.

For the given question;

The total length of silver chain jeweler had = 36 inches.

Length of silver chain required to make necklaces = 4 times.

So, multiply 36 with 4 to get the result;

36 x 4 = 144.

Thus, the silver chain required to prepare the necklaces is 144 inches.

For the making of bracelets = 3 times the length of silver chain.

So, multiply 36 with 3 to get the result.

36 x 3 = 104

Thus, the length of silver chain required to prepare bracelets is 104 inches.

The worth of stereo equipment is $112 and there is a 2.5% processing fee for using a credit card.

Whenever we purchase anything with a credit card we have to pay a processing fee that a Bank charges.

To find the total cost of the stereo equipment, we have to add the worth of the stereo equipment and processing fee for using a credit card.

And to find the processing fee for using a credit card, we have to calculate 2.5% of the worth of the stereo equipment.

So, 2.5/100 x 112 = 2.8

The inequality which represents the possible values for the number of peaches and mangos purchased will be;

⇒ $0.75p + $1.75m = $15

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

Avni and her children went into a grocery store and will buy peaches and mangos.

Each peach costs $0.75 and each mango costs $1.75.

And, Avni has a total of $15 to spend on peaches and mangos.

Now,

Let number of peaches purchased = p

And, Number of Mangos purchased = m

Since, Each peach costs $0.75.

Hence, Total cost of peaches purchased = $0.75p

And, Each mango costs $1.75.

Hence, Total cost of mangos purchased = $1.75m

Since, Avani has a total of $15 to spend on peaches and mangos.

So, An inequality that would represent the possible values of peaches and mangos will be;

⇒ $0.75p + $1.75m = $15

Thus, The inequality which represents the possible values for the number of peaches and mangos purchased will be;
