5 1/2 + 3/4 Give your answer in its simplest form.​

y=3

x=11

hence answer 25

3x+5y=48

2x-y=19

eliminate x to find y

(3x+5y=48)2

(2x-y=19)3

(6x + 10y. = 96)

- minus direct

(6x - 3y. = 57)

=

13y = 39

Note: (10y -(-3y)=13y)

divide by 13 to remain with y

y =3

substitute to any equation to get x lets pick second one

2x-(3)=19

2x-3=19

2x=19+3

2x/2=22/2. (to remain with x value)

x=11

therefore 2x+ y results to 2(11) +3=25

Answer:

2x + y = 25

Step-by-step explanation:

Given equations:

[tex]\begin{cases} 3x + 5y = 48\\\;\;2x-y=19\end{cases}[/tex]

Rearrange the second equation to isolate y:

[tex]\implies 2x-y=19[/tex]

[tex]\implies 2x-19=y[/tex]

Substitute the found expression for y into the first equation and solve for x:

[tex]\implies 3x+5y=48[/tex]

[tex]\implies 3x+5(2x-19)=48[/tex]

[tex]\implies 3x+10x-95=48[/tex]

[tex]\implies 13x=143[/tex]

[tex]\implies x=11[/tex]

Substitute the found value of x into the equation for y and solve for y:

[tex]\implies y=2x-19[/tex]

[tex]\implies y=2(11)-19[/tex]

[tex]\implies y=22-19[/tex]

[tex]\implies y=3[/tex]

Therefore, the solution of the given system of equations is:

To find the value of 2x + y, substitute the found values of x and y into the expression and solve:

[tex]\begin{aligned}\implies 2x+y&=2(11)+3\\&=22+3\\&=25\end{aligned}[/tex]

Therefore:

We can use both according to the given information.

• In 2 triangles if 2 sides of a triangle and 2 sides of another triangle are equal and if any one angle is equal to the angle in another triangle then we use SAS congruence rule

• In 2 triangles if 3 sides are equal to the 3 sides of another triangle then we use SSS congruence rule

• We can also use RHS (Right angle Hypotenuse Side). It is for 2 right angle triangle.

Step-by-step explanation:

add the number of days that the chicken laid 5 or more eggs

5 + 5 + 2 = 12

From the given frequency table, we observe that the chicken lays 5 or more eggs on day 4, 5 and 6, and the eggs laid by the chicken are the greatest on day 4.

A frequency distribution table is a tool for structuring the provided data in a way that makes sense and facilitates comprehension. Two or three columns make up a frequency distribution table.

here, we have,

All of the results are shown in the first column as individual values or as class intervals.

The table's second column contains the results' totals, which also display the frequency as vertical lines. It's not required.

The frequency of each result is revealed in the third column.

The frequency table uses lines to depict the number of laid eggs. Here, 5 is represented using a hashed line over four lines. Thus, we see that the maximum number of eggs laid are 6, on day 4.

Also, the chicken lays 5 or more eggs on day 4, 5 and 6.

Step-by-step explanation:

The y-intercept of the line of best fit is -5.18cm and it is showing the initial height of the plant immediately it was planted and it is not reasonable because it shows a negative height

The general form of the equation of a line in slope intercept form is expressed as;

y = mx + c

where;

m is slope

c is y-intercept.

Now, we are given the equation of the line of best fit as;

y = 0.404x - 5.18

where;

y represents the height of the plant above ground level.

x represents the number of days since it was planted.

a) From the given equation, we see that the slope is; m = 0.404 and that the y intercept is -5.18.

Now, what the y-intercept means is that the height of the plant is 5.18 cm below the ground and this is not reasonable.

The side lengths of the triangle are 89 ft, 132 ft and 159 ft

The given parameters are

Angle, A = 34 degrees

Hypotenuse = 159 ft

The length BC is calculated as

sin(A) = BC/Hypotenuse

So, we have

BC = Hypotenuse * sin(A)

This gives

BC = 159 * sin(34 degrees)

Evaluate

BC = 89 ft

The length AC is calculated as

cos(A) = AC/Hypotenuse

So, we have

AC = Hypotenuse * cos(A)

This gives

AC = 159 * cos(34 degrees)

Evaluate

AC = 132 ft

Here, we have

Angle, A = 34 degrees

Because the triangle is a right triangle, we have

Angle, C = 90 degrees

The sum of angles in a triangle is 180

So, we have

Angle B = 180 - 90 - 34

Angle B = 56

This is calculated as

Area = 0.5 * BC * AC

So, we have

Area = 0.5 * 89 * 132

Evaluate

Area = 5874

Hence, the area is 5874 square units

An equation in French is defined as having one or more variables, whereas an equation in English is any well-formed formula consisting of two expressions combined with an equals sign.

Solving a variable equation includes determining which variables' values result in equality. Unknowns are the variables for which the equation must be solved, while equation solutions are the unknown values that satisfy the equality. An equation is a mathematical phrase with two equal sides separated by an equal sign. An equation is 4 + 6 = 10. We can see 4 + 6 on the left side of the equal sign and 10 on the right.

f\mathopen{}\mathclose{\left(6\right)}f(6)​ = (6-6)(something) + 22​ = 0(something) + 22​ = 22 which has a remainder of 22 when divided by x-6x-6​. f\mathopen{}\mathclose{\left(6\right)}f(6)​ = \boxed{22}.

The remainder theorem states that when a polynomial is divided by a linear term, the remainder equals the value of the polynomial at the root of the linear term. This theorem may be used to determine the roots of a polynomial by dividing it by a linear term and solving for the remainder. For instance, when the polynomial x3+x2-5x+6 is divided by (x2), the result is identical to the polynomial's value at x=2. After finding the remainder, we may determine that the polynomial's root is 2, which we can do by solving for the remainder. This theorem may also be used to discover the roots of higher degree polynomials by combining linear terms.

How to solve?

f\mathopen{}\mathclose{\left(x\right)}f(x)​ can be written as (x-6)(something) + 22​.  

f\mathopen{}\mathclose{\left(6\right)}f(6)​ = (6-6)(something) + 22​ = 0(something) + 22​ = 22​.

Check the picture below.

let's take a looksie at that, notice, if we split the circle into 6 even pieces, we end up with six 60° angles at the center, namely six equilateral triangles as you see there.

now, if we run a dashed line as you see from a corner to the other to make the flatter triangle which is shaded, we end up cutting the equilateral triangle into two equal halves, each with 30° and 30° angles, because the dashed line intercepts the green line at 90°.

well, the flatter triangle from corner to corner, is spanning over two equilateral triangles, if it's owning half of one, it must be also owning half of the other.  What the dickens does that mean?  well, it means the area of the flatter triangle that's shaded, is really the same area as a "whole" of one of those equilateral triangles.

so hmmm we have three of those flatter triangles shaded hmm, so let's simply get the area of three of those equilateral triangles and sum them up.

The solution to probability problem is the expected value for a person that buys one ticket is -$2.32

Probability is a measure of the likelihood or chance that a specific event will occur, expressed as a number between 0 and 1, where 0 represents impossibility and 1 represents certainty.

According to the given information:

To find the expected value, you need to multiply each possible outcome by its probability and then add them together.

In this case, there are two possible outcomes: either the person wins the laptop computer (with a probability 1/1500), or they don't win anything (with a probability 1499/1500).

So, the expected value can be calculated as:

E(x) = (1/1500)($1000) + (1499/1500)(-$3)

E(x) = $0.67 - $2.99

E(x) = -$2.32

So the expected value for a person that buys one ticket is -$2.32.
