1. identity → distributive property on the right gives you 8x + 24 same as right

2. contradiction → left side simplified 4x + 18; right side simplified 4x + 16

3. neither → left side simplified 21x - 14; right side 20x - 13

4. identity → left side simplified 5x - 20; right side simplified 5x - 20

Identity equations have infinitely many solutions (any real number will work)
Contradiction equations have no solution (variable will cancel out and remaining statement is false)
Neither will have one solution for the equation (x coefficients are different)

The sum of 5 consecutive odd integers is 2,555. What is the sum of the first, third, and last integer?

Lilit [14]

Answer:

The sum of the first, third, and last integer is 1533.

Step-by-step explanation:

Step 1: You need to create a equation first:

n + n + 2 + n + 4 + n + 6 + n + 8 = 2555

How did I make the equation?

If n is odd number, n + 2 must be the consecutive odd number

5 , 5 + 2 , 5 + 4 , 5 + 6 , 5 + 8

5, 7, 9, 11, 13 ALL CONSECUTIVE ODD NUMBERS

Step 2: Simplifying the equation

n + n + 2 + n + 4 + n + 6 + n + 8 = 2555

5n + 20 = 2555

Step 3: Solving the equation, with explanation

5n + 20 = 2555 Subtract 20 on both sides

5n = 2535 Isolate the variable by dividing 5 on both sides

n = 507

Step 4: Plug in the value

n + n + 2 + n + 4 + n + 6 + n + 8

507, 507 + 2 , 507 + 4 , 507 + 6 , 507 + 8

507, 509, 511, 513, 515

Step 5: Solve the sum of the first, third, and last integer

507 + 511 + 515 = 1533

Step 6: THE ANSWER

1533

Write an expression to represent: "the difference of 8 squared and a number"

Gnom [1K]

Answer:

The expression is (64 - x).

Step-by-step explanation:

The statement is:

"the difference of 8 squared and a number"

Let the number be denoted by x.

The value of 8 squared is:

$8^{2}=8\times 8\\$

$=64$

Then the expression for the provided statement is:

(64 - x)

Thus, the expression is (64 - x).
