The value of x is 10.

Option C is true.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The expression is,

x/7 = 3x + 20/ 35

Now, We can solve as;

x/7 = 3x + 20/ 35

Multiply 35 in both side,

35 × x/7 = 35 × (3x + 20)/35

5x = 3x + 20

Subtract 3x both side,

5x - 3x = 3x + 20 - 3x

2x = 20

Divide 2 both side,

x = 10

Hence, The value of x is 10.

Option C is true.

The value of the variables are x is 5. and AB is 10

Given, the sides of the rectangle are:

length = 2x ₊ 2 and

breadth = 3x ₋ 2

perimeter of the rectangle = 48 units

2(l ₊ b) = 48

2(3x ₋ 2 ₊ 2x ₊ 1) = 48

2(5x ₋ 1) = 48

10x ₋ 2 = 48

10x = 48 ₊ 2

10x = 50

x = 50/10

x = 5

therefore, length = 2x ₊ 1 = 2(5) ₊ 1 = 11 and

breadth = 3x ₋ 2 = 3(5) ₋ 5 = 10

The Line t || Line v the  value of angle m∠5  is 69.28° .

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.

Given:

Line t || Line v

m∠5 =5x + 45

m∠7 = 12x - 11,

According to given question we have

Line t || Line v

Using the property of interior angles on same sides we get

m∠5 =m∠7

5x + 45=12x - 11

compare like terms we get

45-11=12x-5x

34=7x

x=34/7°

By put the value of x

m∠5 =5x + 45

m∠5 =5*34/7+45

m∠5 =485/7=69.28°

m∠7 =12x - 11=12*34/7-11

So, For this purpose, we know that the

The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.

From the given information:

One number is seven more than six times another number. If the sum of the numbers is 28.

Then

Let The first number = y

The second number = x

Hence, y = (7 + 6x)

Their sum is therefore;

x + 7 + 6x = 28

7x = 21

x = 3

Hence, the second number is a; 7 + 6x = 7 + 6(3);

y = 25.

sin( θ) = 12/13 and tan( θ) = 12/5.

sin θ, cos θ, tan θ are the three important trigonometry functions.

If θ lies in the first quadrant that is 0 ≤ θ < π/2, then the value of all trigonometry functions is positive.

The three most significant trigonometry functions are sin θ, cos θ, and tan θ.

If θ is located in the first quadrant, which is equal to θ/2, then all trigonometric functions have positive values.

The three important trigonometry identities are:

sin²( θ ) + cos²( θ ) = 1

1 + tan²( θ ) = sec²( θ )

1 + cot²( θ ) = csc²( θ )

Now we have,

cos θ = 5/13

Then,

sin²( θ ) + cos²( θ ) = 1

sin²( θ ) + ( 5/13 )² = 1

sin²( θ ) + 25/169 = 1

sin²( θ ) = 1 - 25/169

sin²( θ ) = ( 169 - 25)/ 169

sin²( θ ) = 144/ 169

sin( θ ) = √( 144/ 169 )

sin( θ ) = ± 12/13

Since, 0 ≤ θ < π/2

sin( θ ) = 12/13

Now we know,

tan(θ) = sin(θ) / cos(θ)

tan(θ) = ( 12/13 ) / ( 5/13)

tan(θ) = 12/5

The volume of the glass jar is 87.96 cubic inch.

Volume is a unit used to express how much three-dimensional space is occupied. It is usually represented quantitatively in different imperial measures, such as the gallon, quart, and cubic inch, or in SI-derived units like the cubic meter and liter. The cubic concept of length and volume are connected.

Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it may occupy in three dimensions.

The capacity of the jar is calculated as

Volume of cylinder = [tex]\pi r^{2}h[/tex] = [tex]\pi (2^{2})7[/tex] = [tex]28\pi[/tex] = 87.96 cubic inch.

Hence the capacity of the glass jar is 87.96 cubic inches.

Let the cost of number of movies be x and the cost of number of video games be y.

So, the equations are:

5 x + 3 y = 39

2 x + 12 y = 75

2 x = 75 - 12 y

x = 75/2 - 6 y

Put it in the first one, we get that:

5 ( 75/2 - 6y) + 3y = 39

375/2 - 30 y + 3 y = 39

27 y = 187.5 - 39

27 y = 148.5

y = 148.5 / 27

y = $ 5.5

x = 75/2 - 6 y

x = 37.5 - 6 (5.5)

x = 37.5 - 33
