What is n? Stick around for more points

amm1812

N is a variable in algebra. Variables are letters that represent unknown numbers. Variables can be any letter of the alphabet.

Here's how to use n in an algebraic equation:

5 + n = 12

To find what N represents, let it be the only thing on the left side of the variable:

5 -5 + n = 12 - 5

n = 7

Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream.She rows downstream miles/hour faster th

disa [49]

Answer:

Option D. 9 mi/hr downstream, 6 mi/hr upstream

Step-by-step explanation:

The complete question is

Alicia can row 6 miles downstream in the same time it takes her to row 4 miles upstream. She rows downstream 3 miles/hour faster than she rows upstream. Find Alicia’s rowing rate each way

Define the variables

Let

x -----> Alicia's rowing rate downstream in miles per hour

y ----> Alicia's rowing rate upstream in miles per hour

we know that

The rate is equal to the distance divided by the time

The time is equal to the distance divided by the rate

we have

$\frac{6}{x}=\frac{4}{y}$

$4x=6y$

$x=1.5y$ -----> equation A

$x=y+3$ ----> equation B

equate equation A and equation B

$1.5y=y+3$

$1.5y-y=3$

$0.5y=3$

$y=6$

Find the value of x

$x=1.5(6)=9$

therefore

Alicia's rowing rate downstream is 9 mi/h

Alicia's rowing rate upstream is 6 mi/h

Determine the quadrant(s) in which (x, y) could be located. (Select all that apply.)

djyliett [7]

Answer: D. Quadrant IV

Step-by-step explanation: Numbers with a positive or negative sign are referred to be directed numbers. These numerals are easily found on the number line. 2, 5, -1, -3, -7, 9, and so on are some examples.

As a result: x > 0 and y 0 are both true.

Consider the case of specific directed numbers for x and y. Assume x = 5 and y = -2, and the following is true: (5, -2). In a Cartesian plane, this point can be found in the fourth quadrant.

As a result, in a Cartesian plane, the quadrant in which (x, y) might be found is Quadrant IV.
