if 3 times a number added to 2 is divided by the number plus 9 the result is 5 halves. find the number

Answer:

A) x=4

B) x=35/2

Step-by-step explanation:

calculate the product

A) 5x/2+1=11

multiply both sides of the equation by 2

5x+2=22

move the constant to the right hand side and change its sign

5x+22-2

now subtract the numbers

5x=20

now didvide both sides

5x=20

x=4

B)

calculate the product

2x/7-3=2

multiply both sides of the equation by 7

2x-21=14

move the constant to the right hand side and change its sign

2x=14+21

add the numbers

2x=35

now divide both sides of the equation by 2

x=35/2

Answer:

10°

Step-by-step explanation:

It's a right angle so

90° - 52° = 38°

38 - 8 = 30

30 ÷ 3 = 10

check the work

3 × 10 = 30

30 + 8 = 38

38 + 52 = 90

Answer:

89 degrees

Step-by-step explanation:

supplementary angles add up to 180 degrees, so we can add up A and B and make it equal to 180.

(x-18)+(x-20)=180

2x-38=180

2x=218

x=109

then, we plug in 109 for x in the mB equation.

mB=x-20

mB=109-20

mB=89 degrees

therefore, the measure of B is 89 degrees.

Answer:

B = 89

Step-by-step explanation:

Supplementary angles: A + B = 180

Simplify: x-18 +x -20 = 180

2x-38 = 180

2x = 218

x= 109

B = x-20

B = 89

Step-by-step explanation:

Answer:

6x - 5y does not change as it is parallel so I put x = 5 & y = 4 in this equation and the result is 6 × 5 - 5 × 4 = 30 - 20 = 10 so the parallel equation is 6x - 5y = 10

Answer:

1 90 clockwise rotation 2 90 counterclockwise rotation

Step-by-step explanation:

Transformation is a method required to resize or change the orientation of a given shape or figure. The required answer is:

i. Statements b and d would map Shape l onto Shape II

​ii. Statements a, c, e, and f does not map Shape l onto Shape II​

Transformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation. The translation is a method that requires moving every point in a given shape in the same direction and same unit.

Reflection is a method that involves flipping a given figure about a given reference point or line. Rotation is a method that required turning a given figure at an angle about a reference point. Dilation is a method in which the length of the sides of the figure is either increased or decreased. Thus the answers to the question are listed as follows:

a. a reflection across the y-axis, followed by a 90° clockwise rotation about the origin, and then a translation left 6 units. Does not Map Shape l onto Shape II

​

b. a 90° clockwise rotation about the origin and then a translation left 6 units Answer: Maps Shape l onto Shape II

​c. a 90° counterclockwise rotation about the origin, followed by a reflection across the y-axis, and then a translation left 6 units.

d. Does not Map Shape l onto Shape II​d. a 90° clockwise rotation about the origin, followed by a reflection across the y-axis, and then a translation right 4 units Answer: Maps Shape l onto Shape II

​e. a 180° rotation about the origin, followed by a reflection across the y-axis, and then a 90° clockwise rotation about the answer of the origin: Does not Map Shape l onto Shape II​

f. a reflection across the y-axis, followed by a 90° counterclockwise rotation about the origin, and then a translation right 4 units. Does not Map Shape l onto Shape II​.

/-2      /-2

q = 9

Answer:

The person will have P-4 paintings left      

Step-by-step explanation:

We are told that the total number of painters who entered into the painting donation agreement to the local museum is 12 painters

and they all agreed to donate 48 paintings equally

so each painter will donate

48/12= 4paintings

Since this person already had P paintings in his art collection

his painting will reduce by the 4 paintings he denoted to the local museum\

hence he will have

P-4 paintings remaining

Answer:

There is no difference. 4x and x4 are both meaning 4 times x and x times 4

Step-by-step explanation:

If x = 2, then 4 x 2 = 8.

x4 is the same thing

2 x 4 =  8

Note:

When the numbers are there together, without an operation, it means multiplication.

The value of the expression 4x is 8.

The value of the expression [tex]x^4[/tex] is 16.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

4x and [tex]x^4[/tex]

For x = 2,

4x = 4 x 2 = 8

[tex]x^4[/tex] = [tex]2^4[/tex] = 2 x 2 x 2 x 2 = 16

Thus,

The values of the expression are 8 and 16.
