Step-by-step explanation:

8 seed packets

First, we need to figure out how many plants Emma can grow with each seed packet. To do this, divide 6 plants (the number of plants Emma currently has) by 3 seed packets (the number Emma had to begin with). This will give us a unit rate of "2 plants per seed packet".

Now that we know the unit rate, we can use it to figure out how many seed packets Emma needs to have 16 plants in her backyard. Divide 16 plants (the number of plants Emma wants to have) by 2 plants per seed packet (the unit rate). This will give us 8 seed packets.

Therefore, Emma needs 8 seed packets to have a total of 16 plants in her backyard.

The approximate ordered pair for f(x) = g(x) is given as; (4, 22) from the graph. Option A

We know that there are two equations that can be shown from the set of equations that have been written here and the set of equations that we have are;

f(x) = −2x + 30

g(x) = 3x + 10

We are now trying to see the points at which the equation can be said to be equal. This refers to the point where  f(x) = g(x). How can we be able to obtain this point? If we are to get this point then we must go back and look at the graph very well.

As we are looking at the graph very well we should fix our eyes on any point where the line of two functions can be seen to intersect. Once that happens, we can say that we have reached the point where the two functions can be said to be equal. This point is read from the graph as (4, 22)

As per the unitary method, the number of tulip were 21.

Unitary method:

In algebra, unitary method defines how to find the value of a unit from the value of a multiple and the value of a multiple from the value of a unit.

Given,

Here we have There were 35 bunches of rose and tulip. Each bunch had 12 of the roe flower. There 7 more bunches of tulip than rose.

Now we need to find how many tulip were there.

Let number of bunches of roses be x.

And then the number of bunches of tulips will be x + 7

The total number of bunches of flowers = 35                                                                          

So, it can be written as,

=> x + x + 7 = 35

When we simplify this one then we get,

=> 2x + 7 = 35

Now, we have to subtracting both sides by 7

=> 2x = 28

Then dividing both sides by 2

=> x = 14

So, the number of bunches of roses = 14

Then the number of bunches of tulips = 14 + 7 = 21

Using mathematical operations, we know that the total number of workers in the company is 3,800.

A mathematical "operation" is the process of calculating a value utilizing operands and a math operator.

There are predefined rules associated with the math operator's symbol that must be applied to the supplied operands or numbers.

Parentheses, Exponents, Multiplication, Division, and Addition Subtraction are also known as PEMDAS (from left to right).

So, we know that 80% of all workers are women.

760 people who work for the company are not women.

Which means:
80% = x

20% = 760

Now, calculate the total workers as follows:

80/x = 20/760

20x = 80 * 760

x = 80 * 760/20

x = 3,040 (Women workers)

Total workers: 3040 + 760 = 3,800 workers

Therefore, using mathematical operations, we know that the total number of workers in the company is 3,800.

The measure of the largest angle is 96 degrees.

What is a ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3

The measure of the largest angle in the triangle is 96 degrees.

To find the measure of the largest angle, we can use the fact that the sum of the measures of the angles in a triangle is always 180 degrees.

Let's call the measures of the three angles x, y, and z, where x is the measure of the smallest angle, y is the measure of the middle angle, and z is the measure of the largest angle.

We are given that the ratio of the angles is 3:5:8, which means that x:y:z = 3:5:8.

We can set up the following equation to represent the sum of the measures of the angles in the triangle:

x + y + z = 180

We can also set up the following equation to represent the ratio of the angles:

x : y : z = 3 : 5 : 8

We can use these two equations to find the measure of the largest angle.

First, let's multiply the second equation by 3, 5, and 8 to get:

3x = 15y = 24z

Then, we can substitute these equations into the first equation to get:

15y + 24z = 180

Solving for z, we get:

z = 180 / (15+24) = 180 / 39 = 96

Therefore, the measure of the largest angle is 96 degrees.

The hot air balloon is rising at 600 feet per minute and  the blimp are rising at 250 feet per minute

How fast is the hot air balloon rising?

From the question, we have the following parameters that can be used in our computation:

The height of a balloon over time is represented by the graph

On the graph, we have the following points

(x, y) = (0, 0) and (2, 1200)

The rate is calculated as

Rate = (1200 - 0)/(2 - 0)

Evaluate

Rate = 600

Hence, the rate of rising is 600 feet per minute

How fast is the blimp rising?

From the question, we have the following parameters that can be used in our computation:

The height of a blimp over time is given by y = 250x

The above equation is a linear equation

A linear equation can be represented as

y = mx + c

Where

slope = m

This means that the slope of y = 250x is 250

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

The equation must be constrained with some constraints.

As per the given equation,

8 + x = 32

Put x = 4

8 + 4 = 12 ≠ 32

Put x = 24

24 + 4 = 32 (so it will be the solution)

The solution of the system of equations is (x, y) = (9/2, -7/10).

What is the system of linear equations?

A system of linear equations is a group of one or more linear equations that can be solved by using a simultaneous equation or elimination method. Therefore, by using the substitution method and writing the solution of the system in terms of coordinate point (x, y) = (-1, 1).

To solve a system of equations, we can use any of the following methods:
Substitution method,
Elimination method,
Matrix method.
Let's use the substitution method to solve the given system of equations.
We can solve the first equation for z:
z = 7 - 3x - 2y
Substituting this expression into the third equation, we get:
3x + 2y + 3(7 - 3x - 2y) = 1
This simplifies to:
-5x - 3y + 21 = 1
Adding 5x and 3y to both sides, we get:
21 = 5x + 3y + 1
Subtracting 1 from both sides, we get:
20 = 5x + 3y
Dividing both sides by 5, we get:
4 = x + 3/5 y
Substituting this expression into the first equation, we get:
3(x + 3/5 y) + 2y + 7 = 7
This simplifies to:
2y = -7/5
Dividing both sides by 2, we get:
y = -7/10
Substituting this value into the expression for x, we get:
x = 4 - 3/5(-7/10)
This simplifies to:
x = 4 + 21/10
x = 9/2

Hence, the solution of the system of equations is (x, y) = (9/2, -7/10).

The equation of line in standard form that pass through the point (1, -3) and (-2, -1) is (-2x/3)-y=7/3 where -2/3 is x-intercept and -1 is the y-intercept.

A straight line's equation is given by y=mx+c, where c is the height at which the line intersects the y-axis (often referred to as the y-intercept) and m is the gradient.

The set of points that make up a line in a coordinate system are represented algebraically by a line's equation. An equation of a line is an algebraic expression that represents the many points that together make up a line in the coordinate axis as a set of variables, x, and y.

we are given with;

x1=1, y1=-3

x2=-2, y2=-1

equation of line in standard form:

Ax+By=C

so using formula:

(y−y1)=(y2−y1)(x−x1)/(x2−x1)

(y−(-3))=((-1)−(-3))(x-1)/(-2−1)

(y+3)=(2)(x−1)/(-3)

(y+3)=(2x−2)/(-3)

y+3=(-2x/3)+(2/3)

y=(-2x/3)+(2/3)-3

y=(-2x+2-9)/3

y=(-2x-7)/3

(2x/3)+y=-7/3
