Answer:

[tex]\mathrm{a + 14 = b}[/tex]

For no solutions, put a = b = c = -1, for exactly one solution, put a = 1 and b = c = 0 and for infinite solutions, put a = b = c = 5 in the system of linear equations.

We have the system of equations:

x + y + z = 2   …(1)

a x + b y + c z = 10   …(2)

x - 2 y + z = 4     …(3)

a. The system has no solution.

Put a = b = c = -1 in (2)

We get:

- x - y - z = 10

Now add (1) and (2)

0 = 12

which is not possible.

So, no solution.

b. The system has exactly one solution.

a = 1 and b = c = 0

We have the equations as:

x + y + z = 2   …(1)

x = 10   …(2)

x - 2 y + z = 4     …(3)

c. The system has infinitely many solutions.

a = b = c = 5

We will have the equations:

x + y + z = 2   …(1)

5 x + 5 y + 5 z = 10   …(2)

x - 2 y + z = 4     …(3)

Therefore, we get that, for no solutions, put a = b = c = -1, for exactly one solution, put a = 1 and b = c = 0 and for infinite solutions, put a = b = c = 5 in the system of linear equations.

Just divide the numerator by the denominator . If you end up with a remainder of 0 , then you have a terminating decimal. Otherwise, the remainders will begin to repeat after some point, and you have a repeating decimal.

The term repeating decimals refers to non-terminating decimals that repeat. If the digits after the decimal point end, the number has a terminating decimal expansion.

A repeating decimal or recurring decimal is decimal representation of a number whose digits are periodic and the infinitely repeated portion is not zero. It can be shown that a number is rational if and only if its decimal representation is repeating or terminating

If each unit on the map's grid represents 30 meters and Kampp 150 is in Dra Abul Naga, which is about 1,900 meters east and 250 meters south of distance from Tutankhamen's tomb,then we have to add approximately 64 units to the x axis to include Dra Abul Naga.

Given that each unit on the map's grid represents 30 meters and Kampp 150 is in Dra Abul Naga, which is about 1,900 meters east and 250 meters south of Tutankhamen's tomb.

We are required to find the number of units to be added to x axis that are needed to include Dra Abul Naga.

1 unit=30 meters

Distance in east lie on x axis=1900

Number of units to be added on x axis=1900/30

=63.33

It is equal to 64 units approximately.

Hence if each unit on the map grid represents 30 meters and Kampp 150 is in Dra Abul Naga, which is about 1,900 meters east and 250 meters south of Tutankhamen's tomb,then we have to add approximately 64 units to the x axis to include Dra Abul Naga.

To include Dra Abul Naga, 63.33 units and 8.33 units must be added to the x-axis and y-axis, respectively.

A single unit on the map;'s grid represents 30 meters.

Kampp 150 in Dra Abul is 1900 meters east and 250 meters south of Tutankhamun's tomb.

The distance in the east or x-axis is 1900 meters.

Therefore, the number of units to be added to the x-axis will be:

= 1900 meter ÷ 30 meters

= 63.33 units

Similarly, the distance on the y-axis is 250 meters.

Therefore, the number of units that are needed to be added will be:

= 250 meter / 30 meters

= 8.33 units

Hence, the units that need to be added to the x-axis and y-axis to include Dra Abul Naga is 63.33 units and 8.33 units respectively.

She spent 12% on meat and 25% on vegetables.

Therefore, the amount left will be:

= (100 - 12% - 25%) × 12000

= 63% × 12000

Well, since 24+16 is 40, this would mean we get 40 ounces of purple paint. There is also a 150% difference between 24 and 16, so 2/3 times 24 = 16.

2/3 of the mixture is blue paint, while 1/3 of the mixture is red paint, so 1/3 of 72 is 24.

Thus, the answer is 24 ounces of red paint.

The formula for mass m1 will be as M1 = Fr²/GM2.

What is Newton law of gravitation ?

According to newton's law , force between mass m₁ and m₂ at distance x is given by the following expression is;

F = G m₁m₂ / x²

Where F is the force between two masses m1 and m2 G is the gravitational constant and x is the distance between the two objects.

For Solving for M1 in terms of Fg, G, M2 and r yields;

M1 = Fr²/GM2

To solve for M1 in terms of F, G, M2 and r;

We are required to make M1 the subject of the formula as follows:

F = (G M1M2)/r²

By cross product;

Fr² = G M1M2

by dividing through by G M2; we have;

M1 = Fr²/GM2

The formula for mass m1 will be as M1 = Fr²/GM2.

The value of the expression 3√63 +√28 is 5√7 or 13.228.

A number is a fundamental mathematical unit. For counting, measuring, and comparing quantities, we utilize numbers. A set of symbols, or numerals, used to represent numbers is known as a number system.

A square root is a factor of a number that yields the original number when multiplied by itself.

Consider the expression 3√63 +√28,

Let's assume x = 3√63 +√28

Now,

63 = 3 × 21 = 3 × 3 × 7

28 = 2 × 14 = 2 × 2 × 7

Therefore,

x = 3√63 +√28

x = √ [ 3 × 3 × 7 ] + √ [ 2 × 2 × 7 ]

x = ( √ 3² ) × ( √7 ) + ( √2² ) × √7

x = 3√7 + 2√7

x = ( √7 ) × [ 3 + 2 ]

x = ( √7 ) × 5

x = 5√7

x = 5 × 2.6457

x = 13.228

Hence, the value of 3√63 +√28 is equal to 13.228.

Can you please explain more about what do you mean about write a equation for 37.

Step-by-step explanation:

The domain of the function will be the elements present in Set A and the range will be the elements present in Set B.

Domain of a function:

The domain of a function refers to the set of all possible inputs for the function. For example, we get that the domain of f(x) = x² is all real numbers, and the domain of g (x) = 1 / x is all real numbers except for x = 0( as it will make the function indefinite.) Some special functions can also be defined whose domain are limited.

Domain here will be = Set A

Range of a function:

The range of a function refers to the complete set of all possible resulting values of the dependent variable, after we have substituted the domain.

Range of the function here will be = Set B.
