Goran has $18 in his wallet. Rita has $25 and Kareem has $50 in his wallet.

Algebra is a branch of mathematics that helps translate real-world problems or situations into mathematical formulas. Mathematical operations like addition, subtraction, multiplication, and division as well as variables like x, y, and z are needed to construct a valid mathematical expression. Coordinate geometry, calculus, and trigonometry are just a few of the mathematics topics that involve algebra. A simple algebraic equation is 2x + 4 = 8. Algebraic expressions are the result of performing operations on variables and constants, such as addition, subtraction, multiplication, division, etc.

Let the amount Goran have = X

Then, the amount Rita have= x+7

Then, Kareem has the amount = 2(x+7)

According to question

The total money three of them have = $93

Therefore,

x+x+7+2(x+7) = 93

2x + 7 + 2x + 14 = 93

4x+21= 93

4x= 93-21

4x= 72

x= 18

So,

Goran has $18 in his wallet

Rita have $ 18 +37= $25 in her wallet

Kareem has 2 × 25 = $50 in his wallet

The range of the function is determined as 1 ≤ M ≤ 6.5 kg.

The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

Also we can defined a domain of a function as all the possible values that go into a function.

From the  graph the range of the function of the mass of the bucket is calculated as follows;

The minimum value of the mass of the bucket = 1

The maximum value of the mass of the bucket = 6.5 kg

The range of the function (mass, M of the bucket) = {1, 2, 3, 4, 5, 6.5 kg}

1 ≤ M ≤ 6.5 kg

Thus, the range of the function includes numbers ranging from 1 to 6.5 kg. That is  {1, 2, 3, 4, 5, 6.5 kg}.

Answer

The values of a that ensures that the system has at least one solution is

a > (21/127)

Explanation

We are told to find the values of a that ensures that the system has at least one solution. The system of equations include

3 (a - 5x) < 1 + x

2 - (x/2) > 3 + 5 (x - a)

To do this, we need to solve the expressions

3 (a - 5x) < 1 + x

3a - 15x < 1 + x

We can rewrite this as

1 + x > 3a - 15x

x + 15x > 3a - 1

16x > 3a - 1

Divide both sides 16

We then solve the second one. But to do this, let's multiply through by 2

2 - (x/2) > 3 + 5 (x - a)

4 - x > 6 + 10 (x - a)

we can rewrite as

6 + 10 (x - a) < 4 - x

6 + 10x - 10a < 4 - x

10x + x < 10a - 6 + 4

11x < 10a - 2

Divide both sides by 11

The two solutions are

x > (3a/16) - (1/16)

x < (10a/11) - (2/11)

To find a lasting solution, we need the inequality sign to be the same, so, we need to multiply through one of the equations by -1

x > (3a/16) - (1/16)

-x < (-3a/16) + (1/16)

So, the system of equations become

-x < (-3a/16) + (1/16)

x < (10a/11) - (2/11)

We can then add the two equations

-x + x < (-3a/16) + (1/16) + (10a/11) - (2/11)

0 < (-3a/16) + (10a/11) + (1/16) - (2/11)

0 < -0.1875a + 0.9091a + 0.0625 - 0.1818

0 < 0.7216a - 0.1193

Rewrite

0.7216a - 0.1193 > 0

0.7216a > 0.1193

Divide both sides by 0.7216

(0.7216a/0.7216) > (0.1193/0.7216)

a > 0.1653

a > (21/127)

Answer:

A - 35 copies

B - $4050

Step-by-step explanation:

A-

2300 + 70c = 4750

70c = 4750 - 2300

70c = 2450

c = 35

He sold 35 copies

B-

P = 2300 + 70(25)

P = 2300 + 1750

P = $4050

Total if he sold 25 copies: $4050

Note ; We multiplied each of the x-values with their probabilities and obtain the sum of all. This gives the expected value.

The graphs of the hyperbola have zero point of intersection.

The point of intersection is the point where two or more functions meet.

The given parameters;

3x² – 4y² + 4x – 8y +4= 0

3x² + y² + 4x – 3y +4= 0

To find the points of intersection, we simply equate both equations.

So;

3x² – 4y² + 4x – 8y +4= 3x² + y² + 4x – 3y +4

Now Cancel out the common terms

y² - 3y = - 4y² - 8y

Collect like terms;

y² + 4y²=  3y - 8y

5y² = - 5y

Divide through by 5

y² = -y

Divide through by y

y = -1

Hence, the graphs of the hyperbola have zero point of intersection.

To solve this triangle, we cannot use either the Pythagorean Theorem or the Law of Cosines. We need more information.

Conversely, we can use SOHCAHTOA, in the sense that we can use the SOH part of this (Sine = opposite side over hypotenuse), that is, we can use angle 33 as the reference angle, and we have a right triangle here. Then, using trigonometric ratios, we can use:

We also can use the Law of Sines to solve it:

Therefore, we can solve this triangle using both Law of Sines and SOHCAHTOA. (We can select two options: c and d.)

If the total traveling time is 1 hour 8 minutes f the average speed is 45 km/h.

This is a problem from time and distance. We can solve this equation by following a few steps.

Let's assume the car travel in the city for t minutes and the average speed is v.

According to the question, the car travel outside the city for, (68- t) minutes as 1 hour 8 minutes is equal to 68 minutes.

As per the question, Outside the city, it travels at twice its former speed v.

Now, we can form an equation,  2 (15/t) =  72/(68- t).

Let's simplify the given equation. 30/t = 72/(68- t)

Or, 72t = 30(68- t)                 [cross multiplication]

Or, 72t = 2040 - 30t

Or, 102t = 2040                    [add with +30t both sides]

Or, t = 2040/102    

Or, t = 20                              [dividing by 102 both sides]

Therefore we can conclude that the average speed ( km/h) is (15×60) / 20 = 45 km/h.

We have the next given information:

-18.5% is the percentage of methyl alcohol

- The bottle contains 1.43 L

Now, we need to convert the percentage into a decimal.

Then 18.5% = 0.185

We need to determinate the volume in millimeters for methyl alcohol:

If 143L of solution contains 18.5% of methyl alcohol. Therefore:

The volume of methyl alcohol = 1.43 * 0.185

= 0.26455 L

Then, we need to convert Liters to milliliters:

Step-by-step explanation:

To find the perimeter, you must add the lengths of all sides.

In this question the perimeter is given, which is 63.

63 = 12 + 12 + 3x + 2x + 1 + x + 2

1. Add the numbers

63 = 12 + 12 + 3x + 2x + 1 + x + 2

12 + 12 + 1 + 2 = 27

63 = 27 + 3x + 2x + x

2. Combine Like Terms

63 = 27 + 3x + 2x + x

x = 1
3x + 2x + 1x = 6x

63 = 27 + 6x

3. Move Variable to the left

63 = 27 + 6x

63 = 6x + 27

4. Subtract 27 from both sides, the opposite of adding 27

63 = 6x + 27

63 - 27 = 6x + 27 - 27

36 = 6x

5. Divide by the same factor, the opposite of multiplying 6

36 = 6x

36/6 = 6x/6

6. Cancel out the 6s but leave the x

36/6 = 6x/6

x = 6

So, now that we know that x = 6 we can solve the expression, x + 2, to find out the length of the side BC.

6 + 2 = 8

The dimension of minimum paper size would be 18 inches by 9 inches.

Let the paper size be x inches in length and y inches in width.

The length of the printed space would be x-8 inches and width would be y-4 inches.

Print area would thus be (x-8)(y-4)=50.

From this [tex]$y=4+\frac{50}{x-8}=\frac{4 x+18}{x-8}$[/tex]

Also from the same equation on simplifying, it is x y-8 y-4 x+32=50.

Since the area of the paper of size x inches by y inches is xy, let it be denoted as A.

Thus

[tex]$A-8 y-4 x=18$[/tex] Or [tex]$A=8 y+4 x+18$[/tex]

[tex]$A=\frac{32 x+144}{x-8}+4 x+18$[/tex].

For minimum paper size [tex]$\frac{d A}{d x}$[/tex] must be =0, hence,

[tex]$\frac{d A}{d x}=\frac{32(x-8)-(32 x+144)}{(x-8)^2}+4=0$[/tex]

[tex]$\frac{-400}{(x-8)^2}+4=0$[/tex]

(x-8)² = 100

x-8 = 10

[tex]$\mathrm{x}=18$[/tex], hence [tex]$\mathrm{y}=4+\frac{50}{x-8}=9$[/tex]

Dimension of minimum paper size would be 18 inches by 9 inches.

Thus, the above expression gives the required solution for the inequality.

Answer:

Distance = 9 ft

Explanation:

We can represent the position of the large fish with the number -13 because it is 13ft below the surface. In the same way, we can represent the position of the smaller fish with the number -4.

Then, the distance between the fish will be the absolute value of the difference between their positions. So, the expressions that are equivalent to the distance between the fish are:

| - 13 - ( - 4) | = | - 13 + 4| = 9

or

| -4 - (- 13) | = | - 4 + 13 | = 9

Therefore the distance between the fish is 9 ft

Given that line segment, GC bisects ∠FGH

I made a sketch of the angles, they are not at scale.

That segment GC is an angle bisector indicates that it divides ∠FGH into halves. To determine the measure of the ∠FGC and ∠CGH you have to divide the measure of FGH by 2.

a) ∠FGH=86º

So, in this case, the measure of ∠FGC is 43º.

b) For this item you have to determine the measure of ∠FGH given that the measure of one of the angles determined by the bisector is ∠CGH. To determine the measure of ∠FGH you have to multiply ∠CGH by 2
