80

The number of people in the restaurant will be 80

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that there are 82 people in a restaurant. Four groups of 3 leave and then five groups of 2 enter.

The expression will be solved as below:-

E = 82-12+10

E = 82+10-12

E = 92-12

E = 80

Therefore, the number of people in the restaurant will be 80

Answer:

5, 769 ft

Step-by-step explanation:

The difference between the elevations is

5,763 ft - (-6 ft) = 5, 769 ft

An expression that uses integers to represent the difference between the elevations is 5763-(-6).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given that At its highest point, the elevation of a county is 5,763 feet above sea level. At its lowest point, the elevation of the county is 6 feet below sea level.

If the sea level is assumed to be the origin of a graph, then the elevation above sea level will be represented by a positive y-axis, therefore, the elevation of a county is +5,763. While the elevation below sea level will be represented by a negative y-axis, therefore, the elevation of a county is -6.

Thus, an expression that uses integers to represent the difference between the elevations is,

Difference = Elevation above sea level - Elevation below sea level

= 5763 - (-6)

= 5763 + 6

= 5769

Hence, an expression that uses integers to represent the difference between the elevations is 5763-(-6).

Answer:

c < 7

Step-by-step explanation:

3(6-5c)-2c>4c-129

You will first multiply 3 with 6-5c which will give you 18 and -15c.

18-15c-2c>4c-129

Then you will subtract 2c from -15c because they're like terms. That will give you -17c.

18-17c>4c-129

Next you will put all the variables to one side. To do this, you will add 17c to 4c. You add 17c because that way, you cancel out the -17c and all the variables will be on one side

18>21c-129

Then you will add 129 to both 18 and -129 so that all of the numbers without variables can go on on side.

147>13c

Finally you divide both 147 and 13c by 13. That should give you the final solution of 7>c, or c<7.

Answer:

False

Step-by-step explanation:

Irrational numbers are not integers. All integers are rational numbers.

The statement "some irrational numbers are integers" is false.

Irrational numbers are real numbers that cannot be expressed as fractions or ratios of two integers. They are non-repeating and non-terminating decimal numbers.

Integers, on the other hand, are whole numbers (positive, negative, or zero) without any fractional or decimal components. They can be expressed as ratios of two integers, such as 1/1, -3/1, or 0/1. Integers can also be written as terminating decimals, such as 4.0, -2.00, or 0.

Since irrational numbers cannot be expressed as ratios of integers and integers can be expressed as ratios of integers, it follows that irrational numbers are not integers. Therefore, it is false to say that some irrational numbers are integers.

Step-by-step explanation:

Answer:

An adult ticket costs £7.

A child ticket costs £2.

Step-by-step explanation:

Let a represent the cost for adults and let c represent the cost for children.

Family 1 has a total of 2 adults and 3 children. Together, it cost them £20.

In an equation, this is:

[tex]2a+3c=20[/tex]

Family 2 has a total of 1 adult and 4 children. It cost them £15. In an equation, this is:

[tex]a+4c=15[/tex]

We know have a system of equations. Solve it. We can use the substitution method.

First, subtract both sides by 4c in the second equation:

[tex]a+4c=15\\a=15-4c[/tex]

Substitute this into the first equation:

[tex]2a+3c=20\\2(15-4c)+3c=20[/tex]

Distribute:

[tex]30-8c+3c=20[/tex]

Add:

[tex]30-5c=20[/tex]

Subtract 30 from both sides. The left cancels:

[tex]-5c=-10[/tex]

Divide both sides by -5:

[tex](-5c)/-5=(-10)/-5\\c=2[/tex]

Thus, the cost of a child ticket is £2.

Substitute 2 for c into the equation we manipulated at the start:

[tex]a=15-4c\\a=15-4(2)\\a=15-8=7[/tex]

Thus, the cost of an adult ticket is £7.

Answer:

Adult ticket= $7

Child Ticker=$2

Step-by-step explanation:

Family 1: 2x+3y=20

Family 2: x+4y=15

2x+3y=20

x+4y=15

Multiply by 2

2x+3y=20

-(2x+8y=30)

Change the signs

2x+3y=20

-2x-8y=-30

Eliminate x

-5y=-10

Divide both sides by -5

y=2<---- Price per children

Substitute the value of y

x+4(2)=15

x+8=15

x=15-8

x=7 <----Price per adult

Check:

Substitute the values of x and y to family 1

0.06 cubic meters per year...

Step-by-step explanation:

The rate of water flows through a pipe is 0.06 cubic meters per year.

It is the volume of fluid flows out from the container per unit time.

Given that,

Water flows through a pipe at a rate of 6 fluid ounces per day. It can be written as:

Water flows per day ⇔ 6 fluid ounces

∴ Water flows per year ⇔  365 x (6 fluid ounces)

Volume of water in milliliter,

Water flows per year ⇔  365 x (6 x 29.574 ml )

Volume of water in cubic meter,

Water flows per year ⇔  365 x ([tex]\frac{6 x 29.574}{1000000}[/tex] [tex]m^{3}[/tex]) = 0.06477   [tex]m^{3}[/tex]

Answer and Step-by-step explanation:

We are given a coordinate :

( 3 , -4 )

The first number within a coordinate means the x axis, meaning it moves either left or right.

While the second number within a coordinate means the y axis, meaning it moves up or down.

If a number is positive, it increases, if it is negative, it decreases.

So let's take a look at the first number 3, it is positive and the x axis number, meaning you should say "Moving right on the x axis 3 times"

Now for -4, it is negative and the y axis, meaning you should say "Moving down on the y axis 4 times"

Your final phrase should be :

"(3,-4) is moving right on the x axis 3 times, and moving down on the y axis 4 times"

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

Work Shown:

x = 0.515151...

100x = 51.515151....

Subtract the two equations to get 100x-x = 99x on the left side and 51.515151.... - 0.515151... = 51 on the right side. Notice the decimal portions cancel out.

So we end up with 99x = 51 which solves to x = 51/99

This means 51/99 = 0.515151...

Answer:

17/33

Step-by-step explanation:

We first let 0.51 be x.

Since x is recurring in 2 decimal places, we multiply it by 100.

100x=51.51

Next, we subtract them.

100x−x=51.51−0.51

99x=51

Lastly, we divide both sides by 99 to get x as a fraction.

x=51/99

=17/33

Answer:

The possible midpoints of AB are [tex]\frac{19}{2}[/tex] and [tex]\frac{13}{2}[/tex].

Step-by-step explanation:

Let suppose that A and B have one-dimensional coordinates. GIven that [tex]A = 8[/tex] and [tex]AB = 3[/tex], there are two possible locations for B:

[tex]B_{1} = A+AB[/tex]

[tex]B_{1} =8+3[/tex]

[tex]B_{1} = 11[/tex]

[tex]B_{2} = A-AB[/tex]

[tex]B_{2} = 8-3[/tex]

[tex]B_{2} = 5[/tex]

The midpoint equations for each case are, respectively:

[tex]m_{1} = \frac{A+B_{1}}{2}[/tex]

[tex]m_{1}=\frac{8+11}{2}[/tex]

[tex]m_{1} = \frac{19}{2}[/tex]

[tex]m_{2} = \frac{A+B_{2}}{2}[/tex]

[tex]m_{2} = \frac{5+8}{2}[/tex]

[tex]m_{2} = \frac{13}{2}[/tex]

The possible midpoints of AB are [tex]\frac{19}{2}[/tex] and [tex]\frac{13}{2}[/tex].

Answer:

-4, and (a+b) are the two factors

Step-by-step explanation:

-4(a+b)

We have two factors

-4, and (a+b)

Answer:

-4 and a and b/(a+b)

Step-by-step explanation:

When there is a number outside of a parentheses, you want to distribute it inside of the parentheses.  So in this case, -4 is on the outside, so it usually gets distributed it in, which makes it a factor.

Since a and b are getting multiplied by the -4, they are also factors in the equation.  

In a problem like this, if you want to solve it, the number outside the parentheses gets distributed into the numbers in the parentheses.  (It gets multiplied by the numbers).

-4 times a and -4 times b

-4 times a is -4a

-4 times b is -4b

The answer to this problem, if you need it is -4a-4b.  :)

Answer:

(0, 6)

Step-by-step explanation:

Point T has a coordinate pair of (3, 4). That is, at point T, x = 3, while y = 4.

3 points to the left of T would be a movement on the x-axis. This movement is a run across the x-axis. At T, x = 3. Therefore, 3 points to the left would be a decrease by 3 = 3 - 3 = 0.

3 points to the left of T would leave us with an x coordinate of 0.

2 points above T suggest a rise, which is on the y-axis.

Therefore, at T, y = 4. 2 points above 4 = 4 + 2 = 6. y coordinate would now be 6.

In conclusion, the ordered pair representing 3 points to the left, and 2 points above point T is (0, 6).
