A little mermaid can't swim 12 miles downstream in the same amount of time she can swim 8 miles upstream. The little mermaid speed's in still water is: 4/5 mile per hour.

The distance of the miles can be estimated by using the formula:

distance = speed rate × time

∴

[tex]\mathbf{time = \dfrac{distance}{ rate}}[/tex]

Let the current speed be = x

In the upstream direction;

in the downstream direction;

∴

[tex]\mathbf{t = \dfrac{8}{4 -x}= \dfrac{12}{4+x}}[/tex]

By cross multiply;

8 (4 + x) = 12 (4 - x)

32 + 8x = 48 - 12x

8x + 12x = 48 - 32

20x = 16

x = 16/20

x = 4/5 mile per hour

Therefore, we can conclude that the little mermaid speed's in still water is 4/5 miles per hour.

Answer:

[tex]p=(12.75+7.25)/8[/tex]

Step-by-step explanation:

The money she earned is the remaining money plus the board game price. With the total profit, you divide by the 8 puzzles

Brittany received an amount of $2.50 for each puzzle in her collection.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let's assume the amount of money Brittany received for each puzzle in her collection is p dollars.

Then the total amount of money she received for 8 puzzles will be 8p dollars.

If she used $7.25 to buy a board game, then the amount of money she had before purchasing the board game was 12.75 + 7.25 = $20.

We know that the total amount of money Brittany received for 8 puzzles was 8p dollars. So we can write an equation:

8p = 20

Divide both sides by 8:

p = 2.5

Therefore, he received $2.50 for each puzzle in her collection.

Answer: 8p + -4p = 2p + 6

Combine like terms: 8p + -4p = 4p

4p = 2p + 6

Reorder the terms:

4p = 6 + 2p

Solving

4p = 6 + 2p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '-2p' to each side of the equation.

4p + -2p = 6 + 2p + -2p

Combine like terms: 4p + -2p = 2p

2p = 6 + 2p + -2p

Combine like terms: 2p + -2p = 0

2p = 6 + 0

2p = 6

Divide each side by '2'.

p = 3

Simplifying

p = 3

Mathematical proofs are used to determine if a conjecture or statement is true, or otherwise.

The blanks will be filled with the following texts

From the question, the following parameters are given:

[tex]\mathbf{\angle 1 \cong \angle 2}[/tex] and [tex]\mathbf{l \perp 1}[/tex]

This means that, the first blank will be completed with given.

By converse of alternate interior angles theorem

[tex]\mathbf{\angle 1 \cong \angle 2}[/tex] --- angle 1 and angle 2 are congruent

So, the second blank will be completed with [tex]\mathbf{\angle 1 \cong \angle 2}[/tex]

The above statement means that:

Answer:

[tex]2x + 5 < 19 \\ 2x < 19 - 5 \\ 2x < 14 \\ x < 7[/tex]

Answer:

The result can be shown in multiple forms.

Inequality Form:

−12< x < 7

Interval Notation:

(−12,7)

Step-by-step explanation:

first write |2x+5|<19 as a piece wise

2x+5≥0

To find the interval for the first piece, find where the inside of the absolute value is non-negative.

[tex]\frac{2x}{2}[/tex] ≥[tex]\frac{5}{2}[/tex] divide

x ≥−[tex]\frac{5}{2}[/tex] cancel common factor of 2

x ≥ −5/2.

To find the interval for the second piece, find where the inside of the absolute value is negative.

2x+5 < 0

substract by 5

2x < −5

divide by 2x

2x/2< −5/2

simplify to left side

x < −5 / 2

Simplify the right side.

x <  −5/2

In the piece where 2x+5 is negative, remove the absolute value and multiply by −1

− (2x+5) < 19

Write as a piecewise.

{2x+5 <19           x ≥ − 5/2

− (2x+5) < 19      x <− 5/2

Simplify −(2x+5)<19.

{2x+5<19       x≥−5/2

−2x−5<19      x<−5/2

Solve 2x+5 < 19 when x ≥ −5/2.

2x+5<19 for x.

Move all terms not containing x to the right side of the inequality.

2x < 14

divide by 2

x < 7

Find the intersection of x < 7 and x ≥−5/2.

−5/2 ≤x <7

Solve −2x−5 <19 when x <−5/2.

Move all terms not containing x to the right side of the inequality.

−2x<24

divide by -2

x>−12

Find the intersection of x > −12 and x <−5/2.

Find the union of the solutions.
