Identify the terms and coefficients of −4 √ x + y − 5x

Answer:

3x + (5x -2)

Step-by-step explanation:

X is any number so 3 times a number is 3x. -2 plus 5 times a number is the same as 5 times a number minus 2. And the sum would be 3x + (5x - 2)

Answer: I think y is 32 im not good at this tho

Step-by-step explanation:

Answer:

v = 9.5

Step-by-step explanation:

[tex] \\ \tt \frac{4}{5} (v - 7) = 2[/tex]

[tex] \\ \tt \mapsto \frac{4(v - 7)}{5} = 2[/tex]

[tex] \\ \tt\mapsto \frac{4v - 28}{5} = 2[/tex]

[tex] \\ \tt \mapsto4v - 28 = 2 \times 5[/tex]

[tex] \\ \tt \mapsto4v - 28 = 10[/tex]

[tex] \\ \tt \mapsto4v = 10 + 28[/tex]

[tex] \\ \tt \mapsto \: v = \frac{38}{4} [/tex]

[tex] \\ \tt \mapsto \: v = 9\frac{2}{4} \: or \: 9.5 [/tex]

Answer:

A,C,D

Step-by-step explanation:

Irrational number that keep going and never stop that DONT have a pattern

For example

1/3=0.3

It keeps going on BUT it repeats therefore its rational

Another example

The square root of 13 is 3.6055.......

it keeps going on BUT it doesn't have a pattern therefore its irratianal

Answer:

Step-by-step explanation:

f(x) = 2/3 x + 3

x = 9

f(9) = 2/3 * 9 + 3            Divide 9 by 3

f(9) = 2 * 3 + 3               Combine 2 * 3

f(9) = 6 + 3                    Combine

f(9) = 9                          The answer is just a coincidence. The answer for the next one shouldn't be - 3

f(-3) = 2/3 *(-3) + 3         Divide 3 into - 3

f(-3) = 2*(-1) + 3

f(-3) = -2 + 3

f(-3) = 1

How was this done?

You should observe that whatever value you see on the left in the brackets, appears where the x is on the right. This is a very important concept. You should do your best to understand it because algebra is sort of based on it.

Step-by-step explanation:

That is the mid point

Answer:

lenght = 25 cm

widht = 15 cm

Step-by-step explanation:

Dimensions of the screen

375 = (l - 10) × l

375 = l² - 10l

l² - 10l -375 = 0

(l + 15)(l -25)

l = -15 or l = 25

lenght = 25 cm

widht = 25 - 10

widht = 15 cm

Answer:

Infinitely many solutions

Step-by-step explanation:

6x+18=2(3x+9)

6x+18=6x+18

Since both sides are equal to each other, then there are infinitely many solutions because no matter what x is, both sides will be equal to each other.

Answer:

infinite many solutions, (C)

Step-by-step explanation:

Once you distribute you get 6x+18 on both sides. Meaning that the answer is this has infinite many solutions.

Step-by-step explanation:

1. To simplify this expression, let's go through the orders of operations:

Therefore, the answer is -1.

Answer:

19.5

Step-by-step explanation:

side is 6.5 bigger, so minus the 6.5 from the total perimeter of 65 and divide by 3.

65- 6.5 = 58.5

58.5 ÷ 3 = 19.5

equal sides are 19.5

longer side is 19.5 + 6.5

Answer:

19.5 inches

Step-by-step explanation:

You can interpret this problem as x + x + (x + 6.5)=65, with x being the length of the equal sides.

Simplified, this equation becomes 3x+6.5=65.

Solving, this becomes 3x+6.5-6.5=65-6.5 which comes out as 3x=58.5. Next, we divide this equation by 3 on both sides, which then comes out to x=19.5. Therefore, the length of equal sides are 19.5.

Check: There are two equal sides, so 19.5+19.5. Since the base is 6.5 inches bigger than either of the equal sides, the base is equal to 19.5+6.5=26. Adding these values all together comes out to 19.5+19.5+26=65.

Answer:

[tex]\frac{4}{21}[/tex]

Step-by-step explanation:

In order to find the answer you need to find the common denominator of the two fractions multiply the fractions to receive that common denominator and then subtract to find your answer.

[tex]\frac{1}{3} -\frac{1}{7}[/tex]

Find the common denominator:

[tex]CD=21[/tex]

[tex]1\times7=7[/tex]

[tex]3\times7=21[/tex]

[tex]=\frac{7}{21}[/tex]

[tex]1\times3=3[/tex]

[tex]7\times3=21[/tex]

[tex]=\frac{3}{21}[/tex]

[tex]\frac{7}{21} -\frac{3}{21}[/tex]

Subtract numerators

[tex]7-3=4[/tex]

[tex]=\frac{4}{21}[/tex]

Answer:

Mixed number: 3 1/3

Improper fraction: 10/3

Step-by-step explanation:

Answer:

3 1/3 or 10 / 3

Step-by-step explanation:

7 1/2 divided by 2 1/4 =

Multiply 7 by 2.

7 x 2 = 14

Add 1 to 14 because of the 1 in 1/2.

14 + 1 = 15

7 1/2 turns into 15 / 2.

Do the same for 2 1/4.

Multiply 2 by 4.

2 x 4 = 8

Add 1 to 8 because of the 1 in 1/4.

8 + 1 = 9

2 1/4 turns into 9 / 4.

15 / 2 divided by 9 / 4

KEEP CHANGE FLIP!!

15 / 2 x 4 / 9

15 x 4 = 60 & 2 x 9 = 18

15 / 2 x 4 / 9 = 60 / 18

Let's simplify 60 / 18 by dividing by the greatest common factor; 6.

60 / 6 = 10 & 18 / 6 = 3

10 / 3 = 3 1/3

Hope this helped!

Answer:

  x = (y +2)/3

Step-by-step explanation:

The flowchart is trying to help you see that you "undo" what is done to x, in reverse order.

  x is first multiplied by 3, then -2 is added.

First, we want to undo the addition of -2, so we add the opposite of that to y:

  y = 3x -2   ⇒   y +2 = 3x

Then we want to undo the multiplication by 3, so we divide by 3:

 y +2 = 3x   ⇒   (y +2)/3 = x

The solution for x is ...

  x = (y +2)/3

Additional comment

In your diagram, each box has the inverse operation of the one in the box above it. The inverse of subtracting 2 is adding 2. The inverse of multiplying by 3 is dividing by 3. The arrows connecting the boxes are intended to show you that these inverse operations occur in the reverse order of the original operations, as we described above. (The small box at bottom center might contain "3x".)

Answer:

-19

Step-by-step explanation:

Previous position in sea + change in position= current position

-26+7= -19

Hope this helps! :)

Answer:

It is -19

Step-by-step explanation:

Well, you would do this -26 + 7 because the diver dove 26 feet BELOW sea level, which is also -26. He then ascends 7 feet, which means he is coming UP. So -26 + 7 = -19.

Your question is incomplete.

Update: A. -2.5

Answer:

the length would be 3ft and the width would be 2ft

Step-by-step explanation:

this is because the scale is 1cm:4f ft therefore, 12/4=3 and 8/4=2 which is your final answer

Answer:

LENGTH - 3cm / WIDTH - 2cm

Step-by-step explanation:

Well first off, you would use the scale: 1 cm = 4 ft

With 12, you divide by 4. 12 ÷ 4 = 3

With 8, you also divide by 4. 8 ÷ 4 = 2

So, it would be 3 cm long and 2 cm wide.

Answer:

14/45

Explanation:

Make the denominator of both fractions the same

13/36=130/360

2/40=18/360

130/360-18/360=112/360

112/360=14/45

Answer:

34 mph

Step-by-step explanation:

Average speed = total distance / total time

Total distance = ( 40 × 2 + 30 × 3 )

= 170 miles

Total time = 5 h

So, avg speed = 170/5 = 34 mph
