Answer:

0, 8

Step-by-step explanation:

To find out a distance of these numbers, you shall find out how far each number is, preferably you can use a number line for this.

Step-by-step explanation:

where is the diagram first you have to show figure then I will find m

Answer:

7000

Step-by-step explanation:

lets start with 695

9 is the thousand

you check the number next to 9

less then 4 let it rest

more than 5 let it soar

something like that lol

anyways since 5 is next to the 9 we round up from 9 to the next number which is 10

so that changes the whole number to 7000

hope this makes sense!

Answer:

73degrees-10degrees=63 degrees

Answer: 73 + (-19) = x, x = 73-19 = 54 degrees

Step-by-step explanation: Normally this would be a subtraction equation, but if you're looking for addition you can fix that by adding a negative number- which is the same as subtraction. In this case, the times have nothing to do with the equation itself.

[tex]2\sqrt{3}[/tex]

------------------------

Steps:

1st write out equation

[tex]\frac{\sqrt{60}}{\sqrt{5}} \\[/tex]

Second write the conjugant and multiply it.

[tex]\frac{\sqrt{60}}{\sqrt{5}} * \frac{\sqrt{5} }{\sqrt{5} }[/tex]

After multiplying you should get,

[tex]\frac{10\sqrt{3}}{5}[/tex]

now after simplifying you should get

[tex]2\sqrt{3}[/tex]

Answer:

hey cutie

Step-by-step explanation:

Answer:

Language:

1. Circle All terms

2. 12 or 13

3. 8

4. 12 or 13

Plot:

Get a graph for this one, the number is the first parameter is x, find that x value along the x axis then after finishing it locate v, find y value along the y axis.

Solve:

1. x = 3

2. x = 1

3. x = 3

4. x = x = 5

5. x = 8

6. x = 12

7. x = 9

8. x = 4

9. x = 3

10. x = 6

11. x = 4

12. x = -12

13. x = 5

14. x = 6

15. x = 16

Step-by-step explanation:

Variables - in algebra is a symbol or a letter.

Constants - are numbers

Coefficients - are the numbers that are with variables

Use this description and circle the examples.

For the plot use a gird, or gets a coordinate plane.

Lastely for the Solve example minus or plus the constant with the coefficient and variable forum the constant outside that has been equal to. Then divide by the variable coefficient, and you will get your x value. Example:

34 - 13 = 21 / 7 thus x = 3

Answer:

63

Step-by-step explanation:

We are taking a dilation of 3, so that means we are multiplying by 3. We multiply 3 to 21 to get 63.

Answer:

[tex] = \frac{1}{5} {x}^{2} [/tex]

[tex]\\ \sf\longmapsto \dfrac{7}{x-5}=\dfrac{5}{x+7}[/tex]

[tex]\\ \sf\longmapsto 7(x+7)=5(x-5)[/tex]

[tex]\\ \sf\longmapsto 7x+49=5x-25[/tex]

[tex]\\ \sf\longmapsto 7x-5x=-25-49[/tex]

[tex]\\ \sf\longmapsto 2x=-74[/tex]

[tex]\\ \sf\longmapsto x=\dfrac{-74}{2}[/tex]

[tex]\\ \sf\longmapsto x=-37[/tex]

Answer:

Apart from PB&J and oatmeal, pancakes are the most popular (and best) breakfast meal. They’re nutritious, yummy and can be served with both salty and sweet flavors. But are they easy to make? The recipe may be simple, but there are many things we need to consider.

Step-by-step explanation:

You can re-write this quotient this way :

[tex]\frac{\sqrt{28(x-1)}}{\sqrt{8x^{2} }} = \sqrt{ \frac{28(x-1)}{8x^{2} } }\\[/tex]

What's inside the square root must be greater than or equal to 0, because the domain of the square root function is defined on R+ (which is [0,+∞))

In other word we must find x so that :

[tex]\frac{28(x-1)}{8x^{2}}\geq 0[/tex]

at the end we get

28(x-1) ≥ 0

28x - 28 ≥ 0

28x ≥ 28

x ≥ 1

So the answer is B, x ≥ 1

Hi there!

h(x) = 5x + 11

To find h(7) - 3, we can substitute 7 for x and subtract 3:

h(7) = 5(7) + 11 - 3

Simplify:

h(7) = 35 + 11 - 3

h(7) = 43

h(x) = 5x + 11

h(7) = 5 · 7 + 11 = 35 + 11 = 46

h(7) - 3 = 46 - 3 = 43 ← the end answer

Answer:

Answer: D. 8/3

Step-by-step explanation:

Formular for slope:

[ consider points (x1, y1) and (x2, y2) ]

[tex]slope = \frac{y_{2} - y _{1} }{x _{2} - x _{1} } \\ [/tex]

x1 » 5, y1 » 4

x2 » 13.25, y2 » -18

[tex]sloe = \frac{ - 18 - 4}{13.25 - 5} \\ \\ = \frac{22}{8.25} \\ \\ { \boxed{ \boxed{slope \: = \frac{8}{3} }}}[/tex]

Answer:no se jugamos free

Step-by-step explanation:

High school A:  3 vans + 12 buses = 504 students

High school B: 2 vans + 4 buses = 184 students

Multiply High school B by 1.5:

High school B: 3 vans + 6 buses = 276 students

Subtract High school B from High School A:

6 buses = 228 students

Divide students by buses:

Buses = 228 / 6 = 38 students per bus

Now solve for vans using high school A:

3 vans + 12(38 students per bus) = 504 students

Simplify:

3 vans + 456 students in buses = 504 students

Subtract students in buses from both sides:

3 vans = 48

Divide both sides by 3:

Vans = 16

Answer: vans = 16 students, buses = 38 students
