Answer:

c sorry if its wrong

Step-by-step explanation:

Answer:

y=5

x=-1

Step-by-step explanation:

5x-2y=-15

3x+8y=37

add 2y to both sides

5x=2y-15

divide both sides by 5

x=(2y-15)/5

x=2y/5-3

substitute for x

3(2y/5-3)+8y=37

6y/5-9+8y=37

add 9 to each side

6y/5+8y=46

subtract 8y from both sides

6y/5=46-8y

multiply both sides by 5

6y=5(46-8y)

6y=230-40y

46y=230

y=5

substitute for y

5x-2(5)=-15

5x-10=-15

5x=-5

x=-1

Answer:

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

Answer:

(4,0)

Step-by-step explanation:

Let's solve your system by elimination.

5x+2y=20;6x+5y=24

Multiply the first equation by 5,and multiply the second equation by -2.

5(5x+2y=20)

−2(6x+5y=24)

Becomes:

25x+10y=100

−12x − 10y = −48

Add these equations to eliminate y:

13x = 52

Then solve13x=52for x:

13x=52

(Divide both sides by 13)

x=4

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

5x+2y=20

Substitute 4 for x in 5x + 2y = 20:

(5)(4)+2y=20

2y+20=20 (Simplify both sides of the equation)

2y+20+ −20 = 20 + −20 (Add -20 to both sides)

2y = 0

(Divide both sides by 2)

y=0

Answer:

P = 5/12

Step-by-step explanation:

Answer:

x = 4

y = 5

Step-by-step explanation:

4x = x + 12

^(subtract x from both sides)^

3x = 12

^(divide both sides by 3)^

x = 4

3y = 15

(divide both sides by 3)

y = 5

Answer:

miles

Step-by-step explanation:

Answer:

I think Its D.

Step-by-step explanation:

Its not A because milliliters measures with graduated cylinder and stuff like that.

It's not B because tons is capacity.

Finally, it's not C because kilograms measures weight as well, so that will leave you with the answer D- Miles.

question 3 = $150 because 50% is one half of 100% so 300/2 = 150

Answer:

3. 200

4. 9

Step-by-step explanation:

3. 300 divided by 1.5 is 200 which means 200 was the original price

4. 65 times .4 is 26 so 65 plus 26 is 91 and 100-91 is 9 so she had 9 left over

Answer:

Courtney is bringing 8 snacks

Step-by-step explanation:

Chelsea's snacks are represented as 2x.

2x means 2 · (a number)

If Chelsea brought 16 snacks and the amount of snacks represented by 2x, we have to figure out what times 2 equals 16.

In order to find out, we have to divide.

16 ÷ 8 = 2

This means 2 · 8 = 16

Since the amount of snacks Courtney brings is represented as "x", she would have brought 8 snacks.

Hope this helped! :)

Answer:

Step-by-step explanation:

No real solutions exist. Subtract 8 on both sides to get:

[tex]x^2=-20[/tex]

You cannot take the square root of a negative number without involving imaginary numbers.

Answer and Explanation

__________________________________________________________

__________________________________________________________

The answer is -10 because...

You need to multiply 2 by "x," and to find out what "x" is, we need to add...

[tex]2+-12[/tex]

__________________________________________________________

And if we add  [tex]2[/tex] by [tex]-12[/tex], we get [tex]-10[/tex], which is our answer.

__________________________________________________________

and now, if we add [tex]-20[/tex] by  [tex]8[/tex], we get [tex]-12[/tex], which is what the equation equals, and this is how we know it is correct.

Answer:

x = 5 (see below)

Step-by-step explanation:

Combine like terms by subtracting on both sides:

25 + 8x = 5 + 12x

20 = 4x

Then divide:

20 = 4x

5 = x

Move the variable to the left side of the equation:

x = 5

6.355x10^10

Step-by-step explanation:

Scientific notation is the way of writing a large number between 1 to 10 with a power of 10.

The scientific notation of 63,550,000,000 is  6.355 x [tex]10^{10}[/tex].

It is the way of writing a large number between 1 to 10 with a power of 10.

Example:

2.3 x 10² is a scientific notation of 230

9.1 x 10³ is a scientific notation of 9100

We have,

63,550,000,000

We can write this as,

6355 x [tex]10^{7}[/tex]

We need to make a number between 1 and 10.

So,

Divide and Multiply 1000.

6355/1000 x [tex]10^{7}[/tex] x 1000

6.355 x [tex]10^{10}[/tex]

We see that,

6.355 is a number between 1 and 10 with a power of 10.

Thus,

The scientific notation of 63,550,000,000 is  6.355 x [tex]10^{10}[/tex].

3 is the best representation of the center of given data set.

The correct answer is an option (C).

"It is the average of the given numbers."

"I is the middle value of a sorted list of numbers."

For given question,

We have been given a dot plot

From the given dot plot,

We have data as 0, 0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 4, 5, 5, 5, 5, 5, 5

the total number of students in the class are n = 21

We write 0, 0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 4, 5, 5, 5, 5, 5, 5 as  (3 × 0), (1 × 2), (5 × 2), (4 × 3), 4, (6 × 5)

So, the mean of the above data would be,

[tex]\bar{X}=\frac{0+ (1 \times 2)+ (5 \times 2)+(4 \times 3)+4+ (6 \times 5)}{21}\\\\ \bar{X}=\frac{2+10+12+4+30}{21}\\\\ \bar{X}=2.8\\\\\bar{X}\approx 3[/tex]

From above data we can observe that the middle of the data is 3.

0, 0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 3, 4, 5, 5, 5, 5, 5, 5

So, the median would be,

M = 3

Therefore, 3 is the best representation of the center of given data set.

The correct answer is an option (C).
