Solve: 2(23 + a) = 34

Step-by-step explanation: Notice that the fractions that we're comparing in this problem have different denominators.

When fractions have different denominators, they're called unlike fractions. To compare unlike fractions, we must first get a common denominator.

The common denominator of 4 and 3 will be the least common multiple of 4 and 3 or 12. To get a 12 in the denominator of 1/4, we multiply the numerator and the denominator by 3 which gives us 3/12. To get a 12 in the denominator of 1/3, we multiply the numerator and the denominator by 4 which gives us 4/12.

Now we have the fractions 3/12 and 4/12.

The fraction with the greater denominator is larger so 4/12 is bigger which means that 1/3 is bigger.

1/4 is not greater than 1/3. In fact it is less than 1/3.

We have two fractions, 1/4 and 1/3.

We know that,

For a fraction, when the value of the denominator increases, the value of the fraction decreases.

So here the denominator of 4 is greater than 3.

So 1/4 is less than 1/3.

In other words, 1/4 can be defined as a part when 1 is divided in to 4 parts.

1/3 is one part when 1 is divided in to 3 parts.

So clearly, 1/4 < 1/3.

Hence 1/4 is less than 1/3.

Answer 4.6

Step-by-step explanation:

Answer:

404 tickets to adults have been sold .

325 tickets to students have been sold .

Step-by-step explanation:

A system of linear equations is a set of two or more first degree equations, in which two or more variables are related.

In this case, a system of two linear equations with two unknowns is solved.

To assemble the system of equations you must first define the variables, which in this case will be:

On the one hand, you know that 729 tickets were sold, that is to say that tickets sold for students and adults must add 729. Expressed in an equation this is: x+y=729 equation (A)

On the other hand, you know that during a game, $ 2995 was raised for the sale of those 729 tickets. And you also know that tickets for a high school football game cost $ 3 for students and $ 5 for adults.

Then the proceeds from the sale of tickets for students is 3*x and for adults it is 5*y. And your sum must be $ 2995. Expressed in an equation this is:

3*x + 5*y=2995 Equation (B)

So the system of equations is:

[tex]\left \{ {{x+y=729} \atop {3*x+5*y=2995}} \right.[/tex]

There are several methods of solving a system of equations. In that case, the substitution method will be used, which consists of isolating an unknown element in one of the equations, which will be a function of the other unknown. In the other equation that has not been used, the same unknown is replaced by the expression previously obtained. In this case, the value of variable x in equation (A) will be isolated:

x+y=729 ⇒ x=729-y Equation (C)

Replacing this expression in equation (B) you get:

3*(729-y)+5*y=2995

Solving this equation:

3*729-3*y+5*y=2995

2187+2*y=2995

2*y=2995-2187

2*y=808

y=808÷2

y=404

Remembering that "y" is tickets for admission to a high school football game for adults. this indicates that 404 tickets to adults have been sold .

Replacing this value in equation (C), which is the previously isolated equation, you get:

x=729-y

x=729-404

x=325

Remembering that "x" is tickets for admission to a high school football game for students. this indicates that 325 tickets to students have been sold .

By setting up a system of linear equations, it's found that 325 student and 404 adult tickets were sold.

The subject of this question is a linear system, specifically related to the ticket sales at a high school football game. Let's denote 's' as the number of student tickets sold, and 'a' as the number of adult tickets sold. We'll use the following two equations to reflect the given information:

To solve the system of equations, one method is substitution or elimination. Using the elimination method, you could multiply the first equation by 3, getting 3s + 3a = 2187. Then, subtracting this from the second equation gives 2a = 808. Dividing by 2, we find that a = 404. Plugging this value into the first equation gives s = 729 - 404 = 325. Therefore, 325 student tickets and 404 adult tickets were sold.

Answer: A. 2,604

Step-by-step explanation:

According to the given information the number of sets in rows following arithmetic progression (in short form AP).

Where , 23rd term is 65.

Common difference = 65-63=2

nth term in AP: [tex]a_n=a+(n-1)d[/tex]

For n= 23 , we have [tex]a_{23}=65[/tex] , d= 2

[tex]23=a+(23-1)2\\\\ 23= a+(22)2\\\\ 23=a+44\\\\ a=44-23=21[/tex]

Formula for the sum of first n terms in AP= [tex]S_n=\dfrac{n}{2}[2a+(n-1)d][/tex]

Since, There are 42 rows in the auditorium.

Then,

[tex]S_{42}=\dfrac{42}{2}[2(21)+(42-1)2]\\\\=21(42+82)\\\\=21(124)=2604[/tex]

Hence, the the auditorium contains 2,604 seats.

Thus , the correct answer is A. 2,604

We want to find the total number of seats in the auditorium, knowing that the number of seats is given by an arithmetic sequence.

The correct option is A: there are 2,604 seats in total.

We know that in the row before you (the number 22) there are 63 seats, in your row (number 23) there are 65 seats, and in the next row there are 67 seats, then we can write the 3 terms of a sequence:

[tex]a_{22}= 63\\a_{23} = 65\\a_{24} = 67[/tex]

Is simple to see that this is an arithmetic sequence, such that the difference between consecutive terms is 2, then the number of seats in the n-th row is given by:

[tex]a_n = a_{n-1} + 2[/tex]

or:

[tex]a_n = a_1 + (n - 1)*2[/tex]

Using this second equation, we can find the value of the first term of the sequence:

[tex]a_{23} = 65 = a_1 + 2*(23 - 1)\\\\65 - 44 = a_1 = 21\\[/tex]

Now, if we define d as the difference between consecutive terms in an arithmetic sequence, the sum of the first N terms is given by:

[tex]S(N) = N*(2*a_1 + (N - 1)*d)/2[/tex]

Here we have a total of 42 rows, so we use N = 42.

d =2

a₁ = 21

Then the total number of seats is:

[tex]S(N) = 42*(2*21 + (42 - 1)*2)/2 = 2,604[/tex]

This means that the correct option is A: there are 2,604 seats in total.

The required equation to the given slope m=-5 and a point (-1,3) is 5x+y+2=0

Step-by-step explanation:

Given that the slope  m=-5 and a point (-1,3)

Now we have to find an equation with the given slope and point :

Let [tex](x_1,y_1)[/tex] be the given point (-1,3)

The slope point formula is [tex]y-y_1=m(x-x_1)[/tex]

y-3=-5(x-(-1))

y-3=-5(x+1)

y-3=-5(x)-5(1) ( by using the distributive property a(x+y)=ax+ay here a=-5,x=x and y=1 )

y-3=-5x-5

y-3-(-5x-5)=-5x-5-(-5x-5) ( by using the distributive property a(x+y)=ax+ay  here a=-1,x=-5x and y=-5)

y-3+5x+5=-5x-5+5x+5

y+2+5x=0

5x+y+2=0 which is the required equation

If the committee decides to double the radius, the approximate area of the new playground is; A_new = 6000 sq.ft

We are given the area of a circular playground as;

A = 1500 ft²

Formula for area of Circle is;

A = πr²

Thus;

πr² = 1500

r = √(1500/π)

Now, they want to double the radius. Thus approximate area of the new playground is;

A_new = π * [2√(1500/π)]²

A_new = π * [4(1500/π)]

The function h(x) is vertically stretched by a factor of [tex]\frac{1}{2}[/tex] and is shifted 3 units to the left and shifted 2 units up.

Explanation:

The parent function is [tex]f(x)=x^{2}[/tex]

The translated function is [tex]h(x)=\frac{1}{2}(x+3)^{2}+2[/tex]

By using the function transformation rules, the translated function h(x) is stretched vertically by a factor of [tex]\frac{1}{2}[/tex]

Also, from the function transformation rules, we know that,  [tex]$f(x+b)$[/tex] shifts the function b units to the left.

Thus, the translated function h(x) is shifted 3 units to the left.

By using the function transformation rules, we know that,  [tex]$f(x)+b$[/tex] shifts the function b units upward.

Thus, the translated function h(x) is shifted 2 units upwards.

Thus, the translated function h(x) is vertically stretched by a factor of [tex]\frac{1}{2}[/tex] and is shifted 3 units to the left and shifted 2 units up.
