Step-by-step explanation:

There are 12 children tickets did the group buy.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The group bought 20 admission tickets for $340.

And, Adult tickets cost $20, and children’s tickets cost $15.

Let number of children = x

And, Number of adult = y

Hence, We get;

The system of equations are,

x + y = 20  

y = 20 - x .. (i)

And, 15x + 20y = 340

3x + 4y = 68 .. (ii)

Substitute the value of y from (i) in (ii);

3x + 4(20 - x) = 68

3x + 80 - 4x = 68

80 - 68 = x

x = 12

Thus, There are 12 children tickets did the group buy.

Step-by-step explanation:

In making any measurement, the chances are that our results will not be absolutely accurate.  We can often compare our results with some standard or accepted value to see how closely they agree.  But how much error can be allowed before the result becomes meaningless?

As you may guess, the amount of error that is acceptable varies with the situation.  Suppose you measure the distance on a map between your Scarsdale and Mamaroneck and you get a result of 5 miles.  If the actual distance is 5 1/2 miles, the chances are this error will have no effect on the trip between the two towns. But if the same degree of error existed in the calculations used to send astronauts to the moon, those people would be in big trouble!

Percentage Error =  measured value - accepted value  x 100%

                                             accepted value          

Suppose, you measured the length of a table and obtained a measurement of 202 cm.  A friend also measures the table and obtains a result of 198 cm. To calculate the percentage error in each of the measurements, you need to know the "correct' or “accepted value” of the length of the table. After consulting the manufacturer’s catalog, you find that the table's length is listed as 200 cm in length. This will be used as the accepted value in our calculation.

The calculations of percentage error for the two measurements are shown below. Both measurements show an error of 1%. Your friend has made a measurement which is on the low side of the accepted value and is therefore, negative. You, on the other hand, have made an error on the high side of the accepted value and it is positive.

Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.

Answer:

$26320

Step-by-step explanation:

Percentage solution with steps:

Step 1: We make the assumption that 172000 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100% = 172000.

Step 4: In the same vein, x% = 13760

Step 5: This gives us a pair of simple equations:

100% = 172000(1).

x% = 13760(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left-hand side) of both equations have the same unit (%); we have

100% / x% = 172000 / 13760

Step 7: Taking the inverse (or reciprocal) of both sides sides

x% / 100% = 13760 / 172000

=> x = 8%

Therefore, 13760 is 8% of 172000.

Now, I would multiply 329,000 by 8%(or 0.08) to get the answer 26320

He pays in property taxes $26320 if they live in a $329,000 home in the same area.

We have the following information available from the question is:

The property taxes on a home varies directly with the value of the home. Jack currently lives in a home worth $172,000 and pays $13,760 in taxes.

We have to find the how much would someone pay in property taxes?

Lets assume that:

The home worth cost is $172,000 is 100%

Let the property taxes be x

So, We equal to the value are:

$172,000 = 100%

Similarly, x% = $13,760

This gives us a pair of simple equations:

100% = $172000___(1).

x% = $13760___(2).

By simply dividing equation 1 by equation 2, we get:

100% / x% = 172000 / 13760

Taking the inverse (or reciprocal) of both sides sides

x% / 100% = 13760 / 172000

=> x = 8%

Therefore, 13760 is 8% of 172000.

They live in a $329,000 home in the same area, So

Multiply 329,000 by 8%(or 0.08)

=> 26320

#SPJ2

Answer:

because its a straight line

Step-by-step explanation:

Answer:

Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation. Now we just simplify and solve for x.

(2x-7)+(x+25)+(3x+12)=180

6x+30=180 b/c 2x+x+3x=6x and -7+25+12=30.

6x=150 subtract 30 from both sides of the equation

x=25.

Answer: a

Step-by-step explanation:

Answer:

5x - 3x = 10

2(2x - 1) = 46

6x - 15 = 75

x+(x - 10) = 26

Step-by-step explanation:

5x - 3x = 10

2x = 10  Divide by 2

x=5

2(2x - 1) = 46   Distribute the 2

4x - 2 = 46  Add 2

4x = 48  Subtract by 4

x = 12

6x - 15 = 75  Add 15

6x = 90  Divide by 6

x=15

x + x - 10 =26  Add the x's together and the 10

2x = 36  Divide by 2

x = 18
