Step-by-step explanation:

I came up with the same answer as dinahrosesoto

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

*I am assuming that each equation only appears once instead of twice in this problem

6x-y=18

4x+2y=26

We are solving by elimination, and to do that, we need to make the coefficient of one of the variables the same for both equations. The easiest way would be to multiply the top equation by 2 which would result in

12x-2y=36

4x+2y=26

As we see now, -2 and +2 can cancel out if we add the two equations together. So B is correct.

The other solution to this problem is to get a common coefficient for x to do that we first find the least common multiple of 6 and 4 which is 12

so to get 12 we need to multiply equation 1 by 2 and equation 2 by 3

resulting in 12x-2y=36 and 12x+6y=78 which we can solve by subtraction

Although this second way works, we have to realize that this is not one of the solutions. Instead the solution proposed to multiply by 4 and 6 which actually is just what I did above but multiplying everything by 2 again.

In conclusion, the answers should be A and B

Answer:

Dunes and beaches make up

nearly 1,800 of the 3,000 miles of

seacoast in the five Gulf states,

Georgia, and Puerto Rico. Erosion is

a problem on about 900 miles of

Atlantic and Gulf coast dunes and

beaches in these areas. With the

right kinds of native and naturalized

plants, much of this erosion can be

prevented.

This publication was written to

help people select and use plants to

stabilize and beautify dunes. It is

intended mainly for planners,

iandscapers, nursery operators,

developers, and homeowners. The

information applies to coastal dunes

and beaches of Puerto Rico, Texas,

Mississippi, Louisiana, Alabama,

Florida, and Georgia.

Using plants to control dune

erosion is a high priority of Soil

Conservation Service (SCS) plant

materials programs in coastal states

and the Caribbean Area. From 1973

to 1975, 191 representative dune

sites were studied in Georgia,

Florida, Alabama, and Puerto Rico

(4, 5, 6, 7, 8V These studies

identified more than 200 species of

native and naturalized dune plants

and were supplemented by less

detailed studies in Texas, Mississippi,

and Louisiana.

Of the plant species identified in

the SCS field studies, 43 have good

potential for dune revegctation

because of their favorable

characteristics for erosion control,

their frequency of occurrence, and

their dominance in the natural

ecosystem. This publication

describes each of these 43 plants,

their areas of occurrence, and

propagation techniques.

Ocean waves, littoral drift, and

other natural forces—as well as the

activities of people—determine the

adaptability and suitability of plants

for coastal dunes. This publication

explains how the dune ecosystem

and the actions of people must be

considered in planning revegetation.

It also discusses methods of

preparing the planting site and

establishing and maintaining the

plants.

SCS has selected some of the

featured plants for thorough testing

and comparison. Several years of

tests and field trials are required

before SCS and cooperating agencies

can identify superior plants and

release approved cultivars. These

cultivars are the source of

commercially produced seed and

planting stock used in local

conservation programs.

For further assistance in protecting

coastal dunes, contact your local

SCS office, which generally is listed

in municipal telephone directories

under "United States Government,

Department of Agriculture.

Answer:

y = x + 5

Step-by-step explanation:

Slope (m) formula: \(m=\frac{y_2-y_1}{x_2-x_1}\)

\(m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{8-4}{3-(-1)}\\\\m=\frac{8-4}{3+1}\\\\m=\frac{4}{4}\\\\m=1\)

y = mx + b

y = 1x + b  OR y = x + b

(-1, 4)

y = x + b

4 = -1 + b

+1   +1

5 = b

y = x + 5

Check your answer using y = x + 5 and (3, 8):

y = x + 5

8 = 3 + 5

8 = 8

This statement is true

Therefore, our final answer is, y = x + 5.

Step-by-step explanation:

Experimental probability that in a group of 4 students, at least one of them has hazel eyes is 85%.

The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.

According to the question

In a school, 30% of the students have hazel eyes.

The number of hazel eyes in data is 17

The total number of data sets are 20.

Experimental probability = \(\frac{17}{20}\) × 100%

= 85%

Hence, experimental probability that in a group of 4 students, at least one of them has hazel eyes is 85%.

1. First, divide both sides of the equation by 4.

1÷4 x³/4 = –27/4/4

2. Next, on the left side of the equation, use inverse operations to get rid of the division. This will give us x³ = –27.

3. Then, to solve for x, take the cube root of both sides of the equation.

Cube root of x³ = cube root of –27

4. To check your answer, plug in -3 for x in the original equation and solve.

1÷4 x³ = –27/4

1÷4 (-3)³ = –27/4

1÷4 (-27) = –27/4

1 = 1

Since 1 = 1, the answer checks out.

Therefore, the solution to the equation is x = -3.

Answer:

OM = ON by using concurrency of Δs BOM and DON

Step-by-step explanation:

In the figure ABCD:

∵ AB // CD

∵ CB // AD

∵ In any quadrilateral If every two sides are parallel then

 it will be a parallelogram

∴ ABCD is a parallelogram

∴ AC and BD bisects each other at O ⇒ (properties of parallelogram)

∴ OD = OB ⇒ (1)

∵ BC // AD

∴ m∠CBD = m∠ADB ⇒ alternate angles

∵ M ∈ BC , N ∈ AD , O ∈ BD

∴ m∠MBO = m∠NDO ⇒ (2)

∵ BD intersects MN at O

∴ m∠MOB = m∠NOD ⇒ (3) (vertically opposite angles)

From (1) , (2) and (3)

∴ ΔBOM ≅ ΔDON

∴ OM = ON

By using concurrency of Δs BOM and DON, OM = ON Hence proved ∆AMO ≅ ∆CPO.

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

In the given ABCD:

∵ AB // CD

∵ CB // AD

In any quadrilateral, every two sides are parallel, then it will be a parallelogram.

ABCD is a parallelogram

Thus we can say that AC and BD bisect each other at O

∴ OD = OB ⇒ (1)

∵ BC // AD

∴ m∠CBD = m∠ADB

M ∈ BC , N ∈ AD , O ∈ BD

m∠MBO = m∠NDO ⇒ (2)

BD intersects MN at O

m∠MOB = m∠NOD

So From (1), (2), and (3)

ΔBOM ≅ ΔDON

OM = ON

Hence, proved ∆AMO ≅ ∆CPO.

Step-by-step explanation:

The equation of the line in slope -intercept form is y=x-8, Option b is correct.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the graph let us take two points of line joining which are (8, 0) and (0, -8).

m=-8-0/0-8=1

So slope of line is 1.

Now let us find find the y intercept

0=1(8)+b

0-8=b

b=-8

Slope intercept form of line is y=x-8

Hence,  the equation of the line in slope -intercept form is y=x-8, Option b is correct.

predecessor is the number before

Step-by-step explanation:

example: successor of 65 is 66

predecessor of 65 is 64

Answer:

4

Step-by-step explanation:

The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.

The cube root of 64 is 4.

Before solving the question, let's understand the concept of cube root.

The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.

The cube root is denoted by ∛

Now, we will find the cube root of 64.

Firstly, we have to find factor 64.

64 = 2 × 2 × 2 × 2 × 2 × 2.

64 = ∛4³

64 = 4

Therefore, the cube root of 64 is 4.
