Answer:

I think it is 2.............

Step-by-step explanation:

What is an equation? In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value. The most basic and common algebraic equations in math consist of one or more variables.

Answer: y=5/3x-4

Step-by-step explanation:

Hi, you could find the slope with any 2 points on the line. For accuracy, I will choose the points (6, 6) and (0, -4), meaning when x =6, y=6, and when x=0, y=-4. Then you can set up an equation. Because the line on this graph is linear (meaning straight), the form of the equation would be y=ax+b. (If it was a parabola, it would be y=ax^2+bx+c).

y=mx+b (Or some people prefer y=ax+b, but the same thing).

Now, plug in the x and y values, getting:

6 = 6m+b and -4=0*m+b

When you simplify, you will get that b is -4, and then m is 5/3

So the equation is y=5/3x-4

You can plug the numbers of x and y in to check your answer.

Hope this helps!

Answer:

5/6

Step-by-step explanation:

The "first" dice can land on any number, so there are 6 choices. The "second" can not be the same number as the first one. So there are 5 choices. We multiply to get 6*5=30 ways to roll a different number. There are 6*6 total ways so the probability is 30/36 which simplifies to 5/6.

Complete question :

Runners participating in a charity event will run 2.1 km from the starting point to a water station and then run 1.75 km to the finish, as shown in the diagram below.

How much farther do runners run from the start to the water station than from the water station to the finish?

Answer:

0.35 km

Step-by-step explanation:

From start to water station = 2.1 km

From water station to finish = 1.75 km

Difference in distance = farther distance covered = (2.1 km - 1.75 km) = 0.35 km

SP of a pen =rs 8

loss%=20%

Answer:

276 Guests

Step-by-step explanation:

Calculation to determine how many guest were at the wedding

Guests that choose beef =1/3

Guests that choose chicken= 5/12

Guests that choose vegetarian=69

Now let calculate the how many guest were at the wedding

Let x represent the numbers of guest that were present at the wedding

Hence,

x/3 + 5x/12 + 69 = x

9x/12 + 69 = x

12x/12 - 9x/12 = 69

3x/12 = 69

x/4 = 69

x=69*4

x = 276 guests

Therefore the numbers of guests that were at the wedding is 276

Answer: 276

Step-by-step explanation: Let “x” be the number of guest.

1/3 x +5/12x + 69 = x Simplifying and solving for x … where x = 276

1/3(276) + 5/12(276) + 69 = 276

92 + 115 + 69 = 276

Answer:

Step-by-step explanation:

take reference angle as A

using sin rule

sin A=opposite/hypotenuse

sin A=5/13

sin A=0.38

A=sin 22.5

A =22.5 degree

Answer:

where is the chart?????

Answer:

...

Step-by-step explanation:

1. B

angle A is 63 since 27+90= 117, 180-117= 63 (since a straight line is 180°)

2. 7x + 10 = 150 (since they are vertical angles)

7x = 140

x = 20

now plug in 7(20) +10

140+10=150

Answer:

It is a right triangle

Step-by-step explanation:

Use the Pythagorean theorem:

[tex]a^2+b^2=c^2\\\\3.9^2+8.0^2=8.9^2\\\\15.21+64=79.21\\\\79.21=79.21[/tex]

if they weren't equal, it wouldn't be a right triangle.

Answer:

x=2, y = -4.

or as an ordered pair it is (2, -4).

Step-by-step explanation:

-x + 6y = -26

x + 5y =  -18      Add these 2 equations to eliminate x:

0 + 11y = -44

y = -44/11 = -4.

Now substitute y = -4 in the first equation:

-x + 6(-4) = -26

-x - 24 = -26

-x = -26 + 24 = -2

x = 2.

Check the result by substituting in equation 2:

x + 5y = 2 + 5(-4) = 2 - 20 = -18  - checks out.

The scientific notation representation of 23,000 is 2.3 x 10⁴

To express the number 23,000 in scientific notation, we need to move the decimal point to create a number between 1 and 10, and then multiply it by a power of 10.

Starting with 23,000, we can move the decimal point to the left four places to get 2.3. This means we divided the original number by 10,000 (10⁴). To compensate for this division, we multiply 2.3 by 10,000 in the form of 10⁴.

Thus, the scientific notation representation of 23,000 is 2.3 x 10⁴. The coefficient (2.3) is between 1 and 10, and the exponent (4) indicates the number of decimal places the original number was moved.
