Answer:

Step-by-step explanation:

equation given:   a - 2(4 - a) = 7a - 12

distribute and expand the equation

a - 8 + 2a = 7a - 12

combine similar terms:

a + 2a - 7a = -12 + 8

simplify:

-4a = -4

a = -4 / -4

proof that a = 1

a - 2(4 - a) = 7a - 12

1 - 2(4 - 1) = 7(1) - 12

1 - 2(3) = 7 - 12

1 - 6 = -5

-5 = -5  therefore, the a = 1 is correct.

Steps to solve:

a - 2(4 - a) = 7a - 12

~Distribute left side

a - 8 - 2a = 7a - 12

~Combine like terms on the left side

-a - 8 = 7a - 12

~Add 8 to both sides

-a = 7a - 4

~Subtract 7a to both sides

-8a = -4

~Divide -8 to both sides

a = 1/2

Best of Luck!

Simplify 6 - 8 to -2

n + 1 = 4 * -2

Simplify 4 * - 2 to -8

n + 1 = -8

Subtract 1 from both sides

n = -8 - 1

Simplify -8 - 1 to -9

n = -9

Check answer:

n + 1 = 4(6 - 8)

Let n = -9

-9 + 1 = 4 * (6 - 8)

Simplify 6 - 8 to -2

-9 + 1 = 4 * -2

Simplify 4 * -2 to -8

-9 + 1 = 8

n = 8

Answer:

n=9

Step-by-step explanation:

n+1=4(6-8)

We move all terms to the left:

n+1-(4(6-8))=0

We add all the numbers together, and all the variables

n+1-(4(-2))=0

We add all the numbers together, and all the variables

n+9=0

We move all terms containing n to the left, all other terms to the right

n=9

The answer should be n=9

Answer:

Step-by-step explanation:

each mark represents 0.25

Decimal value positioned at point B is -2.25

A number system is defined as a system of writing to express numbers.

A number line can be defined as a pictorial representation of numbers on a straight line.

In the given number line each line represents 0.25 (zero point two five value).

As B is in between -2 and -3.

So B value is between minus two and minus three

The values which can be between -2 and -3 are -2.25, -2.5, -2.75.

The decimal value positioned at point B is -2.25

Hence decimal value positioned at point B is -2.25

Answer:

The three options are;

1) If p = a number is negative and q = the additive inverse is positive, the original statement is p → q

2) If p = a number is negative and q = the additive inverse is positive, the original statement the inverse of the original statement is ~p → ~q

3) If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q

Step-by-step explanation:

Given a statement if p then q, we have, p → q. The converse of the original statement is then, if q, then p while the inverse of the original statement is then if not p then not q, and the contrapositive statement is then if not q then not p

Mathematically, we have;

The given conditional statement;

If a number is negative, the additive inverse is positive which can be expressed as follows;

The conditional statement is p → q

The converse statement is q → p

The inverse statement is ~p → ~q

The contrapositive statement is ~q → ~p

Therefore, we have;

1) The conditional statement, if p = a number is negative and q = the additive inverse is positive, the original statement which is a conditional statement is therefore p → q

2) If p = a number is negative and q = the additive inverse is positive, the original statement, which is a conditional statement is p → q, the inverse of the original conditional statement is therefore, ~p → ~q

3) If q = a number is negative and p = the additive inverse is positive, the original statement, which is a conditional statement is therefore, q → p, the contrapositive of the original conditional statement  is therefore ~p → ~q.

The three options are;

1) If p = a number is negative and q = the additive inverse is positive, the original statement is p → q

2) If p = a number is negative and q = the additive inverse is positive, the original statement the inverse of the original statement is ~p → ~q

3) If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q

The additive inverse of any number is defined as when it is added to the number it gives zero as a result.

Given a statement if p then q, we have, p → q. The converse of the original statement is then, if q, then p while the inverse of the original statement is then if not p then not q, and the contrapositive statement is then if not q then not p

Mathematically, we have;

The given conditional statement;

If a number is negative, the additive inverse is positive which can be expressed as follows;

The conditional statement is p → q

The converse statement is q → p

The inverse statement is ~p → ~q

The contrapositive statement is ~q → ~p

Therefore, we have;

1) In The conditional statement, if p = a number is negative and q = the additive inverse is positive, the original statement which is a conditional statement is, therefore, p → q

2) If p = a number is negative and q = the additive inverse is positive, the original statement, which is a conditional statement is p → q, the inverse of the original conditional statement is, therefore, ~p → ~q

3) If q = a number is negative and p = the additive inverse is positive, the original statement, which is a conditional statement is, therefore, q → p, the contrapositive of the original conditional statement is, therefore, ~p → ~q

We require to create 2 fractions with the repeating 2 after the decimal point.

let x = 0.22.... → (1) ← multiply both sides by 10

10x = 2.22....... → (2)

Subtract (1) from (2) thus eliminating the repeating decimal

9x = 2 ( divide both sides by 9 )

Answer:

The equation is H = 495 -6t

Step-by-step explanation:

Here, we want to write an equation that will represent the height Juan is above the ground, after t seconds.

The height we want to calculate is H. The initial height is 495 foot;

At the first second, the decrease in height will be 6 * 1, at the second 6 * 2 and thus at t seconds, the decrease in height will be 6 * t = 6t

Ask the height after t seconds will be;

H = 495 - 6t

Where t represents the time in seconds
