Alina is able to swim at a rate of about 2.5 miles per hour. Talia is able to swim at a rate of 1.8 meters per second. Which sta
Masja [62]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

Rate at which Alina swim = 2.5 miles per hour

Rate at which Talia swim = 1.8 meters per second

First we need to change meters per second into miles per hour

As we have given that

1\text{ miles}=1609\text{ meters}

and

1\text{ hour}=3600\text{ seconds}

So, to change into miles per hours, we'll apply this,

\frac{1.8\times 3600}{1609}\\\\=4.02\text{ miles per hour}

So,

Difference between their rates will be given by

4.02-2.5=1.52\text{ miles per hour}

Hence, Talia swims about 1.5 miles per hour faster than Alina.

So, Option 'D' is correct.

Please answer CORRECTLY !!!!!! Will mark brainliest !!!!!!!!!
gulaghasi [49]

Answer:

a= 13+3b

Step-by-step explanation:

Simplifying

a + -7 = 3(b + 2)

Reorder the terms:

-7 + a = 3(b + 2)

Reorder the terms:

-7 + a = 3(2 + b)

-7 + a = (2 * 3 + b * 3)

-7 + a = (6 + 3b)

Solving

-7 + a = 6 + 3b

Solving for variable 'a'.

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

Add '7' to each side of the equation.

-7 + 7 + a = 6 + 7 + 3b

Combine like terms: -7 + 7 = 0

0 + a = 6 + 7 + 3b

a = 6 + 7 + 3b

Combine like terms: 6 + 7 = 13

a = 13 + 3b

Simplifying

a = 13 + 3b

–2|u| = –68<br> ill give 5 oints
german

The solution to the given equation –2|u| = –68 is u = 34, -34.

<h3>What is the solution to the equation?</h3>

Given the equation in the question;

–2|u| = –68

To find u, divide both sides by -2

–2|u| = –68

(–2|u|)/2 = (–68)/-2

|u| = 34

Remove the absolute value term, this create ± on the right side of the equation. ( |x| = ±x )

u = ±34

Hence,

u = 34, -34

Therefore the solution to the given equation –2|u| = –68 is u = 34, -34.
