                                             5

                     (6x^2 + 34x + 25)/(x+5)  = 6x + 4 with a remainder of 5

Answer:

Is, 6x+18+x=7x+2+1

7x+18=7x+2+1

Step-by-step explanation:

x + y + z = 108

x/y = 2/3

y/z = 3/4

x = 2y/3

z = 4y/3

we use these 2 as substitute in the first equation

2y/3 + y + 4y/3 = 108

2y + 3y + 4y = 324

9y = 324

y = 36

x = 2y/3 = 2×36/3 = 2×12 = 24

z = 4y/3 = 4×36/3 = 4×12 = 48

Answer:

Step-by-step explanation:

x= number of fives

y= number of fifties

x+y=98

5x+50y=2605

Solving through elimination...

5x+5y=490

(5x+50y)-(5x+5y)=2605-490

45y=2115

y= 47

x+47=98

x=51

Which means he has 51 fives and 47 fifties

Answer:

x = 3.5

x = 0.1

x = 4

x = 20

(In order top to bottom)

Step-by-step explanation:

2(x) = 7

/2     /2

x = 3.5 (1st one)

60(x) = 6

/60    /60

x = 0.1 (2nd one)

12(x)=48

/12    /12

x = 4 (3rd one)

1/20(x)=1

x20    x20

x = 20 (4th one)

Equations:

1. 2 • x = 7

2. 60 • x = 6

3. 12 • x = 48

4. x • 1 over 20 = 1

Value of x (Answers):

1. 3.5

2. 0.1

3. 4

4. 20

Explanations:

For number 1;

7 ÷ 2 = 3.5

3.5 • 2 = 7

Therefore, 3.5 is your answer for number 1.

For number 2;

6 ÷ 60 = 0.1

0.1 • 60 = 6

Therefore, 0.1 is your answer for number 2.

For number 3;

48 ÷ 12 = 4

4 • 12 = 48

Therefore, 4 is your answer for number 3.

For number 4;

1 over 20 = 0.05

1 ÷ (1 over 20) = 20

20 • 1 over 20 = 1

Therefore, 20 is your answer for number 4.

Hope I made it clear for you, have a nice day!!! (I'm sorry that I am 4 months late.)

Answer:

A) 1/3

B) 3

Step-by-step explanation:

PART A: To calculate the scale factor reduction going from the large shape to the small shape you have to use the equation SF reduction = small/large. Using the figures on the side of the shape I need to have 3/9, which simplifies to get 1/3. This is the final answer.

PART B: To calculate the scale factor enlargement going from the small shape to the large shape you have to use the equation SF enlargement = large/small. Using the figures on the side of the shape I need to have 9/3, which simplifies to get 3. This is the final answer.

Answer:

[tex]-8x^9[/tex]

Step-by-step explanation:

We can split up the exponent into multiple products: [tex](-2x^3)^3=(-2)^3*(x^3)^3[/tex].

We know that [tex](-2)^3=(-2)*(-2)*(-2)=-1*-1*-1*2*2*2=-1*8=-8[/tex].

We also know that [tex](x^3)^3=x^{3*3}=x^9[/tex].

Answer: 186,000

Step-by-step explanation:

You round the 282 down so that it is an even thousand. <3

186,282 rounded to the nearest thousand is 186,000.

To round 186,282 to the nearest thousand, we look at the digit in the thousands place, which is '6'.

If the digit in the hundreds place is 5 or greater, we round up. If it is less than 5, we round down.

In this case, since the digit in the hundreds place is '8', which is greater than 5, we round up.

To round up, we increase the digit in the thousands place by 1 and replace all the digits to the right with zeros.

Therefore, rounding 186,282 to the nearest thousand gives us 187,000.

Step-by-step explanation:

I will assume those are coordinates.

The distance between 2 points is given by  √ (x2 − x1)^2 + (y2 − y1)^2.

Replacing the values, we get  √ (5 − 5)^2 + (6 − -6)^2 =  √0+144 = 12

Answer:

The first factor is equal to −14.9 .

The product is 14.9.

Step-by-step explanation:

This is what i answered in k12 and got it correct.

The product is −14.9. Therefore, option C is the correct answer.

The given expression is 14.9(-1).

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Product of positive and negative integers is negative.

Now, 14.9(-1)=-14.9

The product is −14.9. Therefore, option C is the correct answer.

Answer:2,2

Step-by-step explanation:

Answer:

I think x = -8. Hope this helps!! :)

We want to look at the given graph to estimate the value of f(5). We found that: f(5) = 2

In the coordinate axis, we can see a blue curve, which represents the function f(x).

To find the value of f(5), first, we need to locate the value x = 5 on the horizontal axis.

Once we find it, we need to move vertically until we meet the curve.

Once we meet the curve, we move horizontally until we meet the vertical axis, that intersection gives the value of the function when evaluated in x = 5.

By this method we can see that: f(5) = 2

Answer:

0.2

Step-by-step explanation:

If it takes 10 seconds to move 1 centimetres, and you want to know about 2 seconds, you can divide by 5 on both sides.

1/5 = 0.20

It takes 2 seconds to move 0.2 centimetres (aka 20 milimetres).

The snail will travel 0.2 centimetre in 2 seconds.

it takes the snail 10 seconds to move 1 centimetre. The means in every 10 seconds the snail moves 1 centimetre.

The distance the snail can cover in 2 seconds can be computed below:

10 seconds = 1 cm

2 seconds = ? cm

cross multiply

distance it takes the snail to travel in 2 seconds = 2 / 10

distance it takes the snail to travel in 2 seconds = 1 / 5

distance it takes the snail to travel in 2 seconds = 0.2 cm

Therefore, the snail will travel  0.2 cm in 2 seconds .
