Answer:

202 tickets for adults were sold and 70 tickets for children are sold.

Step-by-step explanation:

Solve this question using simultaneous linear equation.

•Let the number of tickets sold for adults be a

•Let the number of tickets sold for children be b

The question stated that 272 tickets were sold altogether. So:

[tex]a + b = 272[/tex]

Now, make sure that only one of the unknown values remain on the left hand side. For example:

[tex]a = 272 - b[/tex]

I will refer to the above equation as equation 1.

Now, the question also stated that the tickets sold $1694. This means that:

[tex]7a + 4b = 1694[/tex]

I will refer to this equation as equation 2.

Now, substitute equation 1 into equation 2 by replacing the a in equation 2 with the values on the right hand side in equation 1. For example:

[tex]7(272 - b) + 4b = 1694[/tex]

Then just solve the equation by finding the value of b.

[tex]7(272 - b) + 4b = 1694 \\ 1904 - 7b + 4b = 1694 \\ 1904 - 3b = 1694 \\ 1904 - 1694 = 3b \\ 210 = 3b \\ b = 210 \div 3 \\ = 70[/tex]

Lastly, find the value of a. Just take the value of b and then substitute into equation 1.

[tex]a = 272 - b \\ = 272 - 70 \\ a = 202[/tex]

Answer:

x=5

Step-by-step explanation:

3(x−2)=9

Divide both sides by 3.

x-2=9/3

Divide 9 by 3 to get 3.

x−2=3

Add 2 to both sides.

x=3+2

Add 3 and 2 to get 5.

x=5

Answer:

5

Step-by-step explanation:

Answer:

1) $60

2) $45

3) 5 cupcakes ;; function for situation is 30(n)=3n+15

3A) No

3B) No

Step-by-step explanation:

the function is f(x)=3x+15 where x= cupcakes

To find total cost for 15 cupcakes, simply look at the graph or if you don't trust your eyeballing skills, you would calculate it by:

f(15)=3x+15 meaning plug 15 into the equation which equal $60

same for 10 cupcakes

f(10)=3(x)+15 equals $45

# of cupcake order for $30

using the graph we can see that for $30 we can purchase 5 cupcakes

the function for the situation is 30(n)=3n+15

A) No it would not make sense because after substituting 4 for the n, it does not equal to 30

B) Yes it would make sense because substituting 5.2 for n, it equal to $30.6 or $30

see I need help for chemistry pls anyone here helps me I must submit before 10:30

Mean is when you sum up all the numbers in a data set and divide that sum with the total amount of numbers in the data set.

Median is the middle number of a data set.

Mode is the number that shows up the most in a data set.

Best of Luck!

Answer:

The mean is the average of a data set. The mode is the most common number in a data set. The median is the middle of the set of numbers.

Answer:

  25, 31, 38

Step-by-step explanation:

The first differences are increasing by 1 each time. The next differences will be 5, 6, 7, so the next numbers will be 25, 31, 38.

Answer:

The answer is 25 and 31. The pattern is adding the numbers 1, 2, 3 every time it goes up. For example. 10+ 1 = 11, 11 + 2 = 13, 13 + 3= 16, 16+ 4 = 20... and so on. Thus you would add 20 + 5 and get the answer 25. THEN you would add 25 + 6 and get 31.

Answers: 25, 31

Answer: 2, 3, 6 and 7.

Step-by-step explanation:

We have four natural numbers A, B, C and D.

such that all of these numbers are smaller than 10, and:

A < B < C < D.

A, B and C are the ages of the smaller ones, and D is the age of the larger kid.

Now we have the relation

A^2 + B^2 + C^2 = D^2

We can write this as:

D = √(A^2 + B^2 + C^2)

And remember that D must be smaller than 10, then now we can play with the numbers A, B and C in order to find D.

Suppose for example:

A = 1, B = 2, C  = 3

D = √( 1^2 + 2^2 + 3^2) = √(1 + 4 + 9) = √14

This is not a whole number.

Then we have that A^2 + B^2 + C^2 must be a perfect square.

The perfect squares we can aim for are:

4*4 = 16

5*5 = 25

6*6 = 36

7*7 = 49

8*8 = 64

9*9 = 81

now, looking at that comes to my mind to try to reach the 49.

because we can take the 36, add 4 to that (4 = 2*2) and then add 9 (9 = 3*3)

A^2 + B^2 + C^2 = 49

where we can use:

A = 2. B = 3 and C = 6

2^2 + 3^2 + 6^2 = 4 + 9 + 36 = 49

Then we have:

D = √(2^2 + 3^2 + 6^2 ) = √49 = 7

Then the ages of the children (for smallest to largest) are:

2, 3, 6 and 7.

Algebraic equation is

y= 80d

Where

y= total income earned in d days

The expression is different from am equation because of the equal to sign(=)

2l+2w=24

2(3w)+2w=24

6w+2w=24

8w=24

w=3

l=9

The are is 27 units squared.

Answer:

My answer to the question is 3.745kg.

Option B

The required weight of Tai's baby brother weighs 3,745 grams in kilograms is 3.745 kg. Option B is correct.

Given that,
Tai’s baby brother weighs 3,745 grams. What is his weight in kilograms is to be determined.

A kilogram is the standard unit of measurement of weight.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

Here,
1 kilogram = 1000 gram
1 gram = 1 / 1000 kilogram
Multiply both side by 3,745
3,745 gram = 3,745 / 1000 kilogram
3,745 gram = 3.745 kilogram

Thus, the required weight of Tai's baby brother weighs 3,745 grams in kilograms is 3.745 kg. Option B is correct.

Answer:x=4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4−3x=8−4x

4+−3x=8+−4x

−3x+4=−4x+8

Step 2: Add 4x to both sides.

−3x+4+4x=−4x+8+4x

x+4=8

Step 3: Subtract 4 from both sides.

x+4−4=8−4

x=4

Answer:

x=4

Step-by-step explanation:

4-3×=8-4x

4-8=-4x+3x

-4=-×

x=4

Answer:

x=6, y = -9

Step-by-step explanation:

6x + 2y = 18

-4x - 2y = -6

Add the two equations together to eliminate y

6x + 2y = 18

-4x - 2y = -6

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

2x +0y = 12

Divide by 2

2x/2 = 12/2

x = 6

Then find y

6x+2y = 18

6*6 +2y = 18

36+2y = 18

Subtract  36 from each side

36+2y-36 = 18-6

2y = -18

Divide by 2

2y/2 = -18/2

y = -9

Step-by-step explanation:

4x + 8y = 40

4x + (8×0.8) = 40

4x + 6.4 = 40

4x = 33.6

4x÷4 = 33.6 ÷ 4

x = 8.4

Answer:

8.4

Step-by-step explanation:

:D

Step-by-step explanation:

3x - y = 74

4y = x

Replace x in the first expression by 4y

3x - y = 74 ➡ 3(4y) - y = 74

12y - y = 74

11y = 74

y = 74/11 we can use this to find x

4y = x

4 × 74/11 = x

296/11 = x

Answer:

  $133,000

Step-by-step explanation:

The upper end of the contractor's budget is $297,000. If he has already spent $164,000, he can spend as much as ...

  $297,000 -164,000 = $133,000

without exceeding his budget.

He can spend $133,000 more and remain within budget.

Additional comment

Of course, he'd like to come in at the low end of the cost range, so would be very happy to spend only $71,000 more.
