C. all real numbers except x = 1
D. all real numbers

Answers

2(x + 7) - 1 > 15                 3(x + 2) < 2x + 7
2x + 14 - 1 > 15                  3x + 6 < 2x + 7
2x + 13 > 15                       3x - 2x < 7 - 6
2x > 15 - 13                        x < 1
2x > 2
x > 2/2
x > 1

What is an Equation?

An equation is a mathematical statement formed when two expressions are equated using an equal sign.

The equations are useful in determination of unknown parameters.

The equations are of various types, such as Trigonometric equations, quadratic equations.

The system of equations are used to solve complex problems.

Let the smaller number is x.

The larger number is 2 less than three times the smaller number

Then the larger number is 3x -2

The sum of the two numbers is 29

The sum is the output of the mathematical operation, Addition.

The equation formed is :

3x -2 + x = 29

Grouping the variables and the constants

4x = 31

Dividing both side of the equation by 4

x = 7.75

The value of the smaller number is obtained.

the length of a rectangle is 3 meters less than twice the width if the area is 104 square meters find the length

Answers

x-width
2x-3-length

A=lxw
104=(2x-3)(x)
104=2x^2-3x
52=x^2-3/2(x)
52+9/16=x^2-3/2(x)+9/16
841/16=(x-3/4)^2
29/4=x-3/4
x=32/4 or 8

length is 2(8)-3 which is 13 and width is 8

Answer:

l = 13 m

Step-by-step explanation:

Let's call the width of the rectangle x. Then we can form an expression for the length of the rectangle: 2x - 3

Now we need to form an equation for the area of the rectangle and solve it:

x(2x - 3) = 104

2x² - 3x = 104

2x² - 3x - 104 = 0 - now we need to factorize the equation

(2x + 13)(x - 8) = 0

Now we can say that x = 8 or x = -6.

Because we cannot have a negative length, x = 8 m.

Now we can workout the length using the expression that we formed at the beginning:

2x - 3 = l

2(8) - 3 = l

l = 16 - 3

l = 13 m

Choose the correct name for these sets of numbers.

Step-by-step explanation:

The sum of 3 consecutive integers is 144, find the integers.

Answers

Our three consecutive integers can be represented as

X → first integer

X + 1 → second integer

X + 2 → third integer

If the sum of our three consecutive integers is 144, our equation will read...

X + X + 1 + X + 2 = 144

Now, we can simplify on the left. Once we simplify, our equation will now read

3x + 3 = 144

      -3     -3   ← subtract 3 from both sides

       3x = 141  ← divide both sides by 3

       X = 47

X → first integer 47

X + 1 → second integer 48

X + 2 → third integer 49

Therefore, the 3 consecutive integers are 47, 48, and 49.
