A. no solution
B. x = 1
C. all real numbers except x = 1
D. all real numbers
Answer:
C is your answer
Step-by-step explanation:
the smaller number, what is the smaller
number.
The smaller number is 7.75.
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.

Answer: 7
Step-by-step explanation:
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
Answer:
first one is rational numbers and the secound one is inrational nunbers
Step-by-step explanation:
Answer:
2. Rational numbers
3. Irrational numbers
Step-by-step explanation:
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.
