9:12

Step-by-step explanation:

Because 3 x 3 = 9 so 4 x 3 = 12

[tex]\bold{\huge{\orange{\underline{ Solution }}}}[/tex]

[tex]\bold{\underline{ Given \: Rules}}[/tex]

[tex]\bold{\underline{ Let's \: Begin}}[/tex]

According to the Second rule :-

[tex]\sf{ 75+b+83=76+80+d=a+81+85+78+c+e }[/tex]

[tex]\sf{ 158 + b = 156 + d = 166 + a = 78 + c + e ...(1)}[/tex]

According to the first rule :-

[tex]\sf{ 75+76+a+78 = b+80+81+c = 83+86+d+e}[/tex]

[tex]\sf{ 229 + a = 161 + b + c = 168 + d + e ...(2)}[/tex]

From ( 1 ) we got :-

[tex]\sf{ 158 + b = 166 + a, 156 + d = 166 + a }[/tex]

[tex]\sf{ b = 166 - 158 + a, d = 166 - 156 + a }[/tex]

[tex]\sf{ b = 8 + a, d = 10 + a ...(3)}[/tex]

Subsitute (3) in ( 2 ) :-

[tex]\sf{229+a = 161+8+a+c = 168+10+a+e}[/tex]

[tex]\sf{ 229+a = 169+a+c = 178+a+e}[/tex]

We can write it as :-

[tex]\sf{ 229+a = 169+a+c \:or\:229+a = 178+a+e}[/tex]

[tex]\sf{ c = 299-169+a-a\:or\:e = 229-178+a-a}[/tex]

[tex]\sf{ c = 60 \: and \: e = 51 }[/tex]

Subsitute the value of c and e in ( 1 ):-

[tex]\sf{ 158 + b = 156 + d = 166 + a = 78 + 60 + 51 }[/tex]

[tex]\sf{ 158 + b = 156 + d = 166 + a = 189}[/tex]

Now,

[tex]\sf{ For \: b, 158 + b = 189 }[/tex]

[tex]\sf{ b = 189 - 158 }[/tex]

[tex]\sf{ b = 31}[/tex]

[tex]\sf{ For \: d , 156 + b = 189 }[/tex]

[tex]\sf{ d = 189 - 156 }[/tex]

[tex]\sf{ d = 33}[/tex]

[tex]\sf{ For \: a, 166 + a = 189 }[/tex]

[tex]\sf{ a = 189 - 166 }[/tex]

[tex]\sf{ a = 23 }[/tex]

Hence, The value of a, b, c, d and e is 23, 31 ,60 ,33 and 51 .

By counting the numbers of options for each selection, we will see that:

A) The code has five digits, and the first digit is fixed (we know that it must be 7) so we only care for the other 4.

The total number of combinations is given by the product between the numbers of combinations:

C = 1*10*10*10*10 = 10,000 codes

So the correct option is the first one.

B) Again, we need to count the number of options for each possible element.

There are 5 drinks, 6 main dishes, and 3 desserts.

So for a meal of 1 drink, 1 main dish, and 1 dessert, the total number of different combinations is:

C = 5*6*3 = 90

There are 90 different possible meals.

C) How Janice can arrange the 6 books?

We need to count how many options we have for each place on the shelf.

Then the number of combinations is:

C = 6*5*4*3*2*1 = 720

There are 720 ways of ordering the books.

The main difference is that one has the equal sign before it while the other has it after.
You can decide which one to use based on each individual expression. If you are still simplifying, put it like this: ()=. If you are done simplifying and have your answer and are using a parenthesis, put it like this: =()

When a number and variable stick together, this multiplication is implied. So 18b is 18 x d.

Since it has the commutative property, you can also write b18, but the other way is more conventional.

A numerical expression is a mathematical sentence involving only numbers and one or more operation symbols. Because numerical expressions can only contain numbers, expressions containing variables (such as x or y) cannot be considered numerical expressions.

Answer:

70

Step-by-step explanation:

The sum of all the angles of a triangle is 180.

so 47 + 63 + x = 180

110 + x = 180

x = 180-110

x = 70

The sum of the angles in a triangle is 180°. Therefore the value of x in the triangle attached is 70°.

A triangle is a polygon with three sides, three angles, and three vertices (corners). It is one of the fundamental shapes in geometry and has several important properties.

Properties of Triangles

1. Interior Angles: The interior angles of a triangle always add up to 180 degrees. Each angle is measured in degrees, and the sum of all three angles is always a straight angle.

2. Exterior Angles: The exterior angle of a triangle is formed by extending one of its sides. The measure of an exterior angle is equal to the sum of the measures of the two opposite interior angles.

3. Side Lengths: In a triangle, the sum of the lengths of any two sides is always greater than the length of the third side. This property is known as the Triangle Inequality Theorem.

Answer:

A. (12, -6)

Step-by-step explanation:

When a coordinate gets rotated into the bottom right quadrant of a graph, the x and y coordinates switch places and the y-coordinate becomes negative.

Since the coordinate pair was (6, 12), you would switch the spots of the coordinates to get (12, 6).

After that, make the y-coordinate negative (if the y-coordinate was originally negative, make it positive instead) to get (12, -6).

Therefore, the answer is (12, -6).
