y = 2x + 4

y = 2x + 4

y = -1/4x + 2

y = -1/4x + 2

Answer:

Step-by-step explanation:

1. To find  a rational number between two numbers, divide the sum of the number by 2,

(1/4 + 1/2) × 1/2

=> [ (2 + 1)/4] × 1/2

=> 3/4 × 1/2

=> 3/8

3/8 is a rational number between 1/4 and 1/2

3. any positive number is greater than a negative so 1 2 3 4 5 6 7 8 9 and -2

Answer:(1/4 + 1/2) × 1/2

=> [ (2 + 1)/4] × 1/2

=> 3/4 × 1/2

=> 3/8

3/8 is a rational number between 1/4 and 1/2

3. any positive number is greater than a negative so 1 2 3 4 5 6 7 8 9 and -2

x=7

Step-by-step explanation:

x-15=7-5(x-4)

x-15=7-5x+20

+5x        +5x

6x-15=7+20

6x=7+20+15

6x=42

x=7

9514 1404 393

Answer:

  x = 7

Step-by-step explanation:

Eliminate parentheses and collect terms. Then solve the resulting 3-step linear equation.

  x -15 = 7 -5x +20

  x -15 = -5x +27

  6x -15 = 27 . . . . . . step 1, add 5x to put the variable term on one side

  6x = 42 . . . . . . . . . step 2, add 15 to put the constant term on the other side

  x = 7 . . . . . . . . . . . . step 3, divide by the coefficient of the variable

_____

Additional comment

The variable terms have coefficients 1 and -5. We choose to add the opposite of the term with the least coefficient (farthest left on the number line). That way, the variable term ends up with a positive coefficient.

Answer:

3 teachers and 9 tutors

Step-by-step explanation:

Answer:

There are 24 students per teacher and 8 students per tutor. If the academy has 72 students, then 9 tutors would be needed.

Step-by-step explanation:

We will start with the question, how many students does the academy have per teacher. To find this, we need to set up the equation. 144 will be the number of students, 6 will be the number of teachers, and x will be the number of students per teacher.

144/6=x

24=x

So, there are 24 students for every teacher.

We could also do this as a ratio. We would do the same thing. We would divide by six to get our answer.

144:6

Make the six one.

24:1

This shows that there are 24 students for every teacher.

Now to find out how many per tutor.

We will do the same thing as before, minus the ratio, though you could still use the ratio. Remember, 40 is the number of students, 5 is the number of tutors, and x is the number of students per tutor.

40\5=x

8=x

So there are 8 students per tutor.

Now we will use this knowledge to solve for how many tutors are needed if the academy has 72 students.

We will set up our equation. 72 will be the students, we will use eight since that is how many students are needed per tutor, and x will be the number of tutors needed.

72/8=x

9=x

So this means that if the academy has 72 students, then it will need 9 tutors.

The longest possible length of the thread is;

Length = 144 cm

Now, it is first folded in half. This means divided into 2. Thus, we now have length as x/2.

This means the ratio is; 8:18

longer length will be; [tex](\frac{18}{8 + 18})[/tex] [tex]* (\frac{x}{4})[/tex]

Thus, we now have;

18 = (18/26) × (x/4)

18 will cancel out to give; x = 26 × 4

x = 144 cm

Therefore the longest possible length of the thread = 144 cm

The question that should be given:-

A bottle contains 12 litres of soda. Henry has 12 of these bottles. How much soda does he have in all? Write your answer in simplest form.

Solution :-

• 1 bottle contains 12 litres of soda

• Total number of bottles = 12

To calculate how much soda does Henry have in total l, we need to multiply the number of bottles and the number of litres in each bottle. So,

[tex]total \: soda = (12 \times 12)litres[/tex]

[tex]→144 \: litres[/tex]

Therefore, the total soda that Henry has in all is 144 litres

--------------------- ★ -----------------------

{ Note:- Even if it was any other number, then just multiply the given number of litres of soda into the total number of given bottles.

This means that,

Total Soda = Given litres of soda x Total bottles given

Ex:- Total bottles given is 2 bottles

and given number of litres in one bottle is 8, so, multiply 8 x 2 = 16.

This means that total number of litres is 16 litres. }

Given above is an example. Please do misunderstand it with the answer.

Answer:

21

Step-by-step explanation:

You can write this question out with two separate formulas, the first one being H - 5 = T, and the second being H + T = 57. I am using the variables of H and T to show the ages of Hulian and Thomas respectively. From here, we can use the substitution formula since we already know what T is equal to (H - 5). Substituting the equation in, we get a new equation of H + (H + 5) = 57. Subtracting 5 from both sides gives us the equation of H + H = 52, or 2H = 52. Dividing by 2 yields the answer of 26 for Hulian's age. Since we know that Hulian is 5 years older than Thomas, we can subtract 5 from 26, giving us Thomas' age, which is 21.

Answer:

23.5

Step-by-step explanation:

=57/2

Answer:

In short your answer is Options 2, 3 and 4.

Step-by-step explanation:

Option 1:

If you distribute 4 among everything in the parenthesis, you'll get 4 × x = 4x and

4 × 4 = 16. Essentially your answer will be

4x + 16, so this is not equivalent.

Option 2:

If you combine like terms 2x and 2x, you'll get 4x, then add 3 and 1 to get 4. Your answer will be 4x + 4. So this is equivalent.

Option 3:

If you distribute 2 among everything in the parenthesis, you'll get 2 × 2x = 4x and 2 × 2 = 4. Essentially your answer will be 4x + 4, so this is equivalent.

Option 4:

If you combine like terms 3x and x, you'll get 4x. So essentially your answer is

4x + 4, so this is equivalent.

Hope this helped :)

Answer:

0

Step-by-step explanation:

There are 2 ways to find slope. Slope is rise over run, meaning that it is the change in y over change in x. The first way is to use the formula. The formula is as follows [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. Plug the coordinates into the equation and then simplify. This ends up looking like [tex]\frac{8-8}{4+3}[/tex] or [tex]\frac{0}{7}[/tex]. So the slope is just 0 because anything divided by 0 is 0. You could also get the answer of 0 by realizing that this is horizontal. All horizontal lines have a slope of 0.
