The value  of x - 2 in the equation 3x - 6 = 21 is 7.

What is an equation ?

An equation is comparing two equal quantities in different form.Equations can be of many types like algebraic equation, logarithmic equation,trigonometric equations, exponential equations.We can also graph this equations in 2 dimensional and 3 dimensional plane.

According to the question given an equation 3x - 6 = 21 first we have to solve for x or find the value of x.

∴ 3x - 6 = 21.

3x = 21 + 6.

3x = 27.

x = 27/3.

x = 9.

So, the value of (x-2) will be (9-2) = 7.

just need 5 and 6 done due in 20 minutes plz help​

Answers

Step-by-step explanation:

5. Let the equation of the line be y = mx + c

m = (6-15)/(2-(-1)) = -3

sub (2, 6) and m = -3:

6 = -3(2) + c

c = 12

Equation of the line: y = -3x + 12

6. Let the equation of the line be y = mx + c

y-intercept of 7 means c = 7

y = mx + 7

x-intercept: value of x when y = 0

therefore, sub (4, 0):

0 = m(4) + 7

m = -7/4

Equation of the line: y = -7/4x + 7

Nixon has a square piece of wrapping paper that has a total area of 200 square inches. Which point on the number line below represents the measurement closest to the side length of the piece of wrapping paper​

Answers

Answer:

x = 14 inches

Step-by-step explanation:

The area of a square piece of paper is 200 square inches.

We need to find the point on the number line below represents the measurement closest to the side length of the piece of wrapping paper​. It is shown in the attached figure.

Area of a square = x², x is the side length

[tex]x=\sqrt{A} \\\\x=\sqrt{200} \\\\x=14.142\ \text{inches}[/tex]

or

x = 14 inches

So, the side length of the square is 14 inches. It is shown in point A.

What is the inverse of the function f(x) = 2x + 1?

Answers

Answer:

y = x/2 -1/2

Step-by-step explanation:

let’s write this equation as

y = 2x + 1

to find the inverse let’s switch x and y

x = 2y + 1

and solve for y

x -1 = 2y

y = x/2 -1/2

so the inverse is

y = x/2 -1/2

Sally and Joan were able to dust the house in 3 hours together. It takes Joan 10 hours to finish the same job alone. Without help, how long would it take Sally to finish the same job ?

Answers

Answer:

4.3 hours

Step-by-step explanation:

Let the number of hours Sally does a job = x

Let the number did hours Joan does a job be equal to y

Sally and Joan were able to dust the house in 3 hours together.

1/x + 1/y = 1/3

It takes Joan 10 hours to finish the same job alone.

Hence,

1/x + 1/10 = 1/3

1/x = 1/3 - 1/10

Least common dey = 30

1/x = 10 - 3/30

1/x = 7/30

Cross Multiply

x × 7 = 30

7x = 30

x = 30/7

x = 4.2857142857 hours

Approximately = 4.3 hours

Without help, it would take Sally 4.3 hours to finish the same job.

Instructions: Write and solve an equation to find the measure or angle x.

Answers

Answer:

x = 30

Step-by-step explanation:

Okay the triangle should add up to 180.

The square represents a right angle = 90°

So just do this

60° + 90° + x = 180 (collect like terms)

150° + x  = 180 (subtract 150 on both sides)

x = 30

Hope this helps ya!

Answer:

x = 30

Step-by-step explanation:

the trinagle has an angle of 180.

and the trainage has a 90°  next to the 60

So

60° + 90° + x = 180 (there are term)

150° + x  = 180

subtract 150 on both sides

150 - 150  180-150 =  x = 30
