The evaluated value of x from the line geometry given is 36.

An angle is the point where two lines meet. From the given diagram, the sum of the angles on the line is 180 degrees.

Take the sum to have

x + 3x + x = 180

Simplify

4x + x = 180

5x = 180

Divide both sides by 5

5x/5 = 180/5

x = 36

Hence the value of x from the diagram is 36

Charlie used 400 milliliters of Solution B if the resulting mixture is a 12% alcohol solution.

An algebraic equation is a declaration of the equality of two expressions created by applying the algebraic operations to a set of variables.

Monomial expressions, binomial expressions, and polynomial expressions are the three main categories of algebraic expressions.

Given : Solution A contains 20% alcohol, while Solution B contains 6% alcohol.

It is  also given that Charlie uses 300 milliliters of Solution A.

Let's say that the mixture contained x ml of the 6% solution B.

x + 300 = resulting mixture of 12 % alcohol.

20% (300) + 6% (x) = 12% (x+300)

60 + 0.06x = 0.12x + 36

0.06x = 24

x = 400 milliliters

As a result, if the resulting mixture is a 12% alcohol solution, he used 400 milliliters of Solution B.

The value of expression c − a + b d on simplification is (-10101.2).

As per question we need to solve the given equation i.e., c − a + b d

And we are provided with the values of a, b , c and d.

Here we have ,

a=78,

b=−716

c=0.8

and d=14

The given equation is,

c − a + b d

Now we need to substitute the value of a, b, c and d. On substituting the value of a, b, c and d , we get

(0.8) - 78 + (-716) (14)

= (0.8) - 78 - 10024

= (-10101.2)

So, we can conclude that the value of given expression on simplification is  (-10101.2).

Natural or whole numbers are all the numbers that can be get by adding ones to one {1, 2, 3, 4, ...}

Integers are like the above ones, but also includes the zero and negative numbers.

Rationals are the ones that can be written as a quotient between two integers, and irrationals are these ones that can't be written like that.

Finally, real numbers are all the numbers.

In this case we have the square root of a prime number, √2, this is always a irrational number.

Answer: 54

C(x) is related to its parent function c(x) = 0.75|x| + 25.

The function in the context of the situation illustrated that the cost is the same.

It should be noted that a function is used to show the relationship between the variables.

In this case, the cost to travel X miles east or west on a train is the same. The function for the cost is given as c(x) = 0.75|x| + 25.

Let East = positive direction

Let West = negative direction

Let the travel distance in East = x

Travel distance for West = -x mile

The cost to travel East x miles will be:

= 0.75(x) + 24

= 0.75x + 25

The cost to travel West will be:

c(-x) = 0.75x + 25

This shows that the cost will be the same even though there in different directions.

Hence, 120 different toppings pizza are possible

STEP 3: Answer question b

Data:

• B = 70°

• b = 19ft

• C = 90°

Procedure:

• Finding the angles

We know that C = 90° as the image shows the symbols. Also, we know that the sum of the interior angles of a triangle are 180°. Then, to get A we have to do the following:

Isolating for A:

Replacing the values we know:

• Finding side ,a

Using trigonometric functions, we can get a.

As we already know the value of A and b, we can isolate for a:

Replacing the values:

• Finding side ,c

Isolating for c:

Replacing the values:

Answer:

• A = 20°

• a = 6.92 ft

• c = 20.22 ft

Based on the equations given, the best comparison between them is that they are intersecting but not perpendicular.

When lines are perpendicular to each other, one line will have a slope that is the negative reciprocal of the other. For instance, if the slope of one line is 2, the slope of the perpendicular line will be -1/2.

Parallel lines will have the exact same slope.

The slope of the first line is:

2x - 7y = -5

(2x - 7y = -5) x 1/7

2/7x - y = -5/7

Slope = 2/7

The slope of the second line is:
x - 3y = 4

(x - 3y = 4) x 1/3

1/3x - y = 4/3

Slope = 1/3

The slopes are neither negative reciprocals nor the same so the lines must be intersecting but not perpendicular.

A store sold 22 colored shirts and 8 white shirts.

Let x be the number of colored shorts and y be the number of white shirts.

A store sold 14 more colored shirts than white shirts.

so, we get an equation,

x = y + 14                       ....................(1)

The white shirts cost $9.95, and the colored shirts cost $10.50. The store sold $310.60 worth of shirts.

So we get an equation,

10.50x + 9.95y = 310.60           .............(2)

Substitute above value of x in equation (2)

10.50(y + 14) + 9.95y = 310.60          

10.50y + 147 + 9.95y = 310.60          

20.45y = 310.60 - 147

20.45y = 163.6

y = 8

Substitute above value of y in equation (1)

So, x = 8 + 14

x = 22

Angle JKL has a measure of 24 degrees while angle LKM has a measure of 12 degrees

The possible question is added at the end of the solution and as an attachment

From the attached figure, we have the following angles

From the attached figure, we can see that:

Angle 1 is twice the measure of angle 2

This is so because, the angle 1 is the vertex angle of an isosceles triangle

While the angle 2 is half of it

So, we have

Angle 1 = 2 * Angle 2

Substitute the known values in the above equation

So, we have

2 * 3x = 5x + 4

Evaluate the product

So, we have

6x = 5x + 4

Evaluate the like terms

x = 4

Substitute x = 4 in the equations JKL=5x+4 and LKM=3x

So, we have

JKL= 5 x 4 + 4

LKM = 3 x 4

Evaluate the equations

So, we have

JKL= 24

LKM = 12

Hence, the measures of the angles are JKL= 24 and LKM = 12, respectively

a) The distance that the bus traveled varies directly with time.

b) If the journey of 60 km takes 8 hours, the speed of the bus is 7.5 km/h.

The relationship between distance and speed can best be explained below:

For a constant speed, for example, 60 km/h, the distance traveled, 60 km, is proportional to the time used.

But if the distance is fixed at 60 km, the time it takes the bus, for example, 8 hours, is inversely proportional to the speed.

Total distance = 60 km

Steady speed = 60 km/h

Thus, for every kilometer, the bus takes one minute (60/60) and for every minute, the bus travels a kilometer.

Answer: 1*5=5 is the counterexample.

Step-by-step explanation: The conjecture stated is that the product of two positive numbers is always greater than either number. We have to find certain values to check and see if this conjecture is false. We can use the numbers 1 and 5 to multiply. This would be the identity property of multiplication. 1 and 5 are both positive numbers and therefore that 1*5=5 is the counterexample.

The value of complex number is [tex]ab^{2}[/tex] = 36+18i

What is complex number?

The complex number is basically the combination of a real number and an imaginary number. The complex number is in the form of a+ib, where a = real number and ib = imaginary number.

The alphabet i is referred to as the iota and is helpful to represent the imaginary part of the complex number. Further the iota(i) is very helpful to find the square root of negative numbers.

Given,

a = 4+2i

b = 3

[tex]b^{2}[/tex] = 3(3)
