Answer:

AC = 19

Step-by-step explanation:

A__C__S

AS = AC + CS

6x -4 = (4x-1) + 7

6x - 4 = 4x + 6

6x - 4x = 6+ 4

2x = 10

x = 10/2

x = 5

AC = 4x -1 = 4(5) - 1 = 20 - 1 = 19

I hope I helped you^_^

Answer:

19

Step-by-step explanation:

AS = AC + CS

6x - 4 = 4x -1  +7

6x - 4 = 4x + 6

Add 4 to both sides,

6x = 4x + 6 + 4

6x = 4x + 10

Subtract 4x from both sides

6x- 4x = 10

2x = 10

Divide both sides by 2

x = 10/2

x = 5

AC= 4x - 1

    = 4*5 - 1

     = 20 - 1

     = 19

Find the area use 3.14 for pi

Answers

Answer:

15.14 cm^2

Step-by-step explanation:

Area of rectangle = 4cm x 3 cm = 12cm^2

Radius of the circle = 2 cm

Area of 1/4 of a circle = (pi x r^2) / 4

= (3.14 x 4) / 4 = 3.14 cm^2

3.14 cm^2 + 12cm^2 = 15.14 cm^2

34+50+45

34+50=84+45=129, 129 estimated=130, and since their is no answer choice but C it should be C, I could be very wrong though.

a. 5/12

b. 7/12

c. 11/12

d. i don’t know

Answers

Answer:

B.[tex]\frac{7}{12}[/tex]

Step-by-step explanation:

[tex]m=\frac{3}{2}\\n=\frac{1}{2\\} \\\frac{1}{2} (m-\frac{2}{3} n)=\frac{1}{2} (\frac{3}{2} -\frac{2}{3} .\frac{1}{2} )\\=\frac{7}{12}[/tex]

So B is the correct answer.

Expression is a combination of operators, variables and numbers.. The value of the expression 1/2 (m-2/3n) when m=3/2 and n= 1/2 is 7/12.

What is Expression?

Expression is a combination of operators, variables and numbers.

The given expression is one by two  times of m minus two by three times n.

1/2 (m-2/3n)

where m and n are two variables with values m equal to three by two 3/2 and n equal to one by two.

1/2 (3/2-2/3(1/2))

Firstly we solve the value in parenthesis.

1/2 (3/2-1/3)

LCM of two, three is six

1/2 ((9-2)/6)

Subtract nine and two we get seven

1/2 (7/6)

Now one by two times of seven by six

7/12

So value of the expression 1/2 (m-2/3n) when m=3/2 and n= 1/2 is 7/12.
