Answer:

7

Step-by-step explanation:

To solve this, we have to solve for h.

We can use order of operations to figure this one out.

[tex]18h-9h-7h+3=17\\18h-9h-7h=14[/tex]

Now that every variable on the left side of the equation has an h, we can factor.

[tex]h(18-9-7)=14\\h=\frac{14}{18-9-7} \\h=\frac{14}{2} \\h=7[/tex]

Answer:

12 hours

Step-by-step explanation:

X = 6:30

From 6:30 am to 6:30 pm = 12 hr

The number of hours that Ben worked at the restaurant can be calculated by the expression, Xpm - Xam.

The number of hours that Ben worked can be represented as:

= Time he finished working - Time he started working

= X pm - X am

If for instance, he started work at 7 am and finished at 12 pm, he would have worked:

= 12 - 7

= 5 hours

The expression that shows the length of time he worked can therefore be concluded to Xpm - Xam.

Answer:

30% decrease in price

Step-by-step explanation:

Since 70-49=21, we know that the price decreased by 30 pounds. The formula to find a percentage decrease is that you should then divide the original number(70) by 21(that equals 0.3!) 0.3 as a percentage would then be 30%, so the answer is there is a 30% decrease in price.

There are no solutions to this system.

==========================================================

Explanation:

Let's simplify and rearrange terms for the first equation. The goal is to get it into the form Am+Bn = C, where A,B,C are constants.

4(m-n) = 7(1-n)

4m-4n = 7-7n

4m-4n+7n = 7

4m+3n = 7

Let's do the same for the second equation

(3/2)n = 4 - 2m

3n = 2(4-2m)

3n = 8 - 4m

4m+3n = 8

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

The result of each simplification is that we ended up with 4m+3n on the left hand side for each equation. The only difference is that we got 7 for the first equation and 8 for the next one.

This is a contradiction because 4m+3n can only equal one number at a time for any given (m,n) pair. It's like saying z = 7 and z = 8 at the same time, where z = 4m+3n. But z can only equal one value at a time.

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

In summary, the given system leads to a contradiction and the system is inconsistent. This means that there are no solutions. There are 0 ordered pairs (m,n) that make both original equations to be true.

The correct answer is there is exactly one ordered pair ([tex]m = \dfrac{73}{56}[/tex] , [tex]n = \dfrac{13}{14}[/tex] ) that satisfies the given system of equations.

Given

[tex]4(m - n) = 7(1 - n)[/tex]

[tex]\dfrac{3}{2} n = 4 - 2m[/tex]

First, simplify the second equation:

[tex]\dfrac{3}{2} n +2m = 4[/tex]

Now,  solve this equation for n:

[tex]n = (4 - 2m) * \dfrac{2}{3}[/tex]

[tex]n = \dfrac{(8 - 4m)}{3}[/tex]

Now, substitute this value of n into the equation [tex]4(m - n) = 7(1 - n)[/tex] :

[tex]4(m - \dfrac{(8 - 4m)}{3}) = 7(1 - \dfrac{(8 - 4m)}{3}[/tex]

[tex]m = \dfrac{73}{56}[/tex]

From the value of m, substitute it back into the equation for n:

[tex]n = \dfrac{(8 - 4m)} { 3}[/tex]

[tex]n = \dfrac{13}{14}[/tex]

The solution is one ordered pair  [tex]m = \dfrac{73}{56}[/tex]  and  [tex]n = \dfrac{13}{14}[/tex].

B. Nine less than a number, all divided by three = [tex]\frac{n-9}{3}[/tex]

The next term of the sequence of the numbers 2, 5, 4, 10, 8, 20, is 16.

A Sequence is a list of numbers that are in order. Sequence follows a particular pattern.

Therefore, let's study the pattern of the sequence to know the next term.

2, 5, 4, 10, 8, 20,

The pattern can be explained as follows;

2(2) = 4

5(2) = 10

10(2) = 20

8(2) = 16

Therefore, the next term of the sequence of the number is 16.

We want to see which is the conic equation that has 2 squares with the same sign and different leading coefficients.

We will see that it is the equation of the ellipse.

Now let's see why that is the correct answer.

The general conic equation is of the form:

[tex]A*(x - a)^2 + B*(x - b)^2 = R^2[/tex]

Where A and B are the leading coefficients, (a, b) is the center of the figure, and R is the average radius of the figure.

For example, if A = B, this would be the equation of a circle, but we must have two different leading coefficients.

If we write:

A = 1/C

B = 1/K

(both are positive, because "it has two squares with the same signs").

Then we get the equation:

[tex]\frac{ (x - a)^2}{C} + \frac{(x - b)^2}{K} = R^2[/tex]

We get the equation we wanted.

The same sign in both square parts and different leading coefficients.

The above equation is the general equation of an ellipse.

Answer:

  12,00,000 rupees

Step-by-step explanation:

The fraction originally intended for each son was ...

  (1/3)(1 -2/5) = 1/3(3/5) = 1/5

The fraction each son actually received was ...

  (1 -1/6)(1/5) = (5/6)(1/5) = 1/6

The difference in these amounts as a fraction of the original distribution is ...

  1/5 - 1/6 = (6/30) -(5/30) = 1/30

Then the original distribution is 30 times this difference:

  30×40000 rupees = 12,00,000 rupees
