Rectangle P = 6.7 cm

Rectangle S = 34/5 =  6.8 cm

Rectangle T = [tex]\sqrt{36.5}[/tex] = 6.04 cm

Answer:

Your answers should be a = 135 adult tickets and s = 186 student tickets.

Step-by-step explanation:

1. Solving for variable s by manipulating variable a:

a + s = 321

a = 321 - s (subtract s to the other side to get a by itself)

$3.50(321-s) + $2.50s = $937.50 (substitution from step 2)

$1123.50 - $3.50s + $2.50s = $937.50 (distributive property)

$1123.50 - $1.50s = $937.50 (combine like terms)

-$1.00s = -$186 (subtraction property of equality)

s = 186 student tickets.

2. Solving for variable a by manipulating variable s:

a + s = 321

s = 321 - a

$3.50a + $2.50(321-a) = $937.50

$3.50a + $802.50 - $2.50 a = $937.50

$1.00a = $135

a = 135 adult tickets.

If you plug both numbers into the original equations, they should come out to be true equations. 135 + 186 = 321 and $472.5 + $465 = $937.5, so these two numbers are your answers for a and s accordingly.

Using the elimination method, we need to eliminate one of the variables by a process of subtraction or addition depending on the case. We can use multiplication or division before eliminating in order to eliminate.

a + s = 321

3.50a + 3.50s = 1123.50 (multiply entire equation by 3.50 in order to eliminate variable a by subtraction)

Now, we can use elimination:

3.50a + 3.50s = 1123.50

3.50a + 2.50s = 937.50

0a + 1s = 186, or s = 186 student tickets.

The same process can be used to solve for variable a. Your answers should be a = 135 adult tickets and s = 186 student tickets.

Explanation:

Points A, C, U, D, S and E are all in the bottom floor plane. A plane is a flat surface, and saying "points are coplanar" means the points are all on the same plane.

Points like R, T and B are not on the floor plane, so they are not coplanar with the other points mentioned in the previous paragraph.

In other words, point R is not coplanar with points C, D and E since R is not on the floor plane with C,D,E.

Finding x:_____________________________________________            

From the Exterior angle property, we know that the measure of an exterior angle is the sum of the 2 opposite interior angles

So, using the property

(3x-10) = (25) + (x + 15)

3x - 10 = 25 + x + 15

3x - 10 = 40 + x

3x-x - 10 = 40              [subtracting x from both sides]

2x - 10 = 40

2x = 50                        [adding 10 on both sides]

x = 25                          [dividing both sides by 2]

Hence, the value of x is 25

5x+9=2x+7+3x-15

0=17

7x+5x-7=21+10x

2x=28

x=14

24-3x=8+2x+16-x

The waves move faster at higher temperatures and in a solid phase because there is more energy and the particles are closer together.

Energy is a quantifiable quality that may be imparted to a body or a physical system and is visible in the way things work as well as in the way that things radiate heat and light.

Higher temperatures imply more energy, and particles are close together in a solid phase.

As a result, highly energetic particles collide with nearby particles, which then collide with further particles.

Higher temperatures cause waves to move more quickly; in a solid phase, more energy is there but the particles are farther apart.

less energy is present but the particles are closer together; more energy is present but the particles are farther apart.

Equivalent to 175 cents

She has 5 dimes and 25 nickels

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

Explanation:

n = number of nickels

d = number of dimes

n+d = 30 since she has 30 coins of just these two types

n = 5d because she has five times as many nickels compared to dimes

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

We'll use substitution to solve this system

n+d = 30

5d+d = 30 ... replace n with 5d

6d = 30

d = 30/6 ... divide both sides by 6

d = 5

Sophie has 5 dimes

n = 5d

n = 5*5 ... plug in d = 5

n = 25

Sophie also has 25 nickels

(5 dimes) + (25 nickels) = 30 coins total

This confirms we have the right coin counts.

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

Let's find the value of each stack of coins

1 nickel = 5 cents

25 nickels = 125 cents (multiply both sides by 25)

1 dime = 10 cents

5 dimes = 50 cents (multiply both sides by 5)

(5 dimes) + (25 nickels) = (50 cents) + (125 cents) = 175 cents

175 cents = (175/100) dollars = 1.75 dollars

√(-2)²+12+14=√16+14=4+14=18

Step-by-step explanation:

The value of expression (√a² + 12) + |b| when a = -2, b = 14 is 16.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

Constant: A constant is a fixed numerical value.

Variable: A variable is a symbol that doesn't have a fixed value.

Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.

Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

Given expression

(√a² + 12) + |b|

a = -2

b = 14

Substituting value of a and b in the expression

(√-2² + 12) + |14|

= (√4 + 12) + 14

= (√16) + 14

= 4 + 14

= 16

Hence, 16 is the value of expression (√a² + 12) + |b| when a = -2, b = 14 .

To solve for x, we need to know that the angles inside of a triangle is always equal to 180º.

[tex]\tt Steps:[/tex]

Since all the angles added together are equal to 180º, we simply have to add the two given angles and subtract that from 180º.

[tex]\tt 43+60=103\\180-103=77\\x=77[/tex]

[tex]\large\boxed{\tt Our~final~answer: ~x=77}[/tex]

Answer:

Step-by-step explanation:

If P, Q and S are collinear, then the three points lies on the same straight line.

If the Straight <P Q S is divided into 2 angles, <P Q R and <R Q S, by ray Q R, then;

<P Q R + <R Q S = 180

Given

<R Q S =x+1

<P Q R = 3x-5

Substitute the given expression into the formula and calculate x;

3x-5+x+1 = 180

collect like terms

3x+x - 5+1 = 180

4x-4 = 180

4x = 180+4

4x = 184

divide both sides by 4

4x/4 = 184/4

x = 46°

To get m∠PQR, we will substitute x = 46 into the expression for m∠PQR.

m∠PQR = 3x-5

m∠PQR = 3(46) - 5

m∠PQR = 138 - 5

m∠PQR = 133°

Hence the measure of angle m∠PQR is 133°

The measure of angle m∠PQR is 133° and the measure of angle m∠RQS is 47° on straight angle ∠PQS.

Given that, points P, Q and S are collinear, then the three points lies on the same straight line.

The straight ∠PQS is divided into 2 angles as ∠PQR and ∠RQS, by ray QR, then ∠PQR + ∠RQS = 180°

Here, ∠PQR = (3x-5)° and ∠RQS =(x+1)°

So, (3x-5)°+(x+1)°=180°

4x-4=180

4x=184

x=184/4

x=46

Now,

∠PQR = (3x-5)°

= 3×46-5

= 138-5

= 133°

Hence, the measure of angle m∠PQR is 133° and the measure of angle m∠RQS is 47° on straight angle ∠PQS.
