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.

What is y = -3x in standard form?

worty [1.4K]

For Ax+By=C, we have y=-3x. We want both the y and x variable on the same side, and that leads us to either subtract y from both sides or add 3x to both sides. You can do either, but I personally prefer the latter, so we have 3x+y=0. We have A=3 (since that is the coefficient for x) and B=1 (since 1*y=y). Lastly, C=0

How

Alecsey [184]

Answer:

A one solution

Step-by-step explanation:

4(x - 5) = 3x + 7

Distribute

4x - 20 = 3x+7

Subtract 3x from each side

4x-3x-20 = 3x+7-3x

x -20 = 7

Add 20 to each side

x -20+20 = 7+20

x = 27

There is one solution
