I would add like terms, meaning subtract 6.4 from both sides.

3.5n = 36.1

<h2>Answer:</h2>

n= 361/35

alternative forms:

n= 10 11/35 or n= 10.3142857

<h2>Step-by-step explanation:</h2>

3.5n+6.4=42.5

move constant to the right

3.5n=42.5-6.4

subtract 42.5 to 6.4

3.5n=36.1

divide both sides by 3.5

----------------

n=361/35

P/2 = 3/4 + p/3 solve for p<br> Show your work<br> It is URGENT

il63 [147K]

Step-by-step explanation:

p/2 = 3/4 + p/3

p/2 - p/3 = 3/4

(3p - 2p )/6 = 3/4

p/6 = 3/4

multiply both sides by 6

p = 3×6/4

=18/4

=9/2

=4.5

What is the equation of a line, in point- slope form, that passes through (5, -3) and has a slope of 2/3?

Alika [10]

<h3><u><em>Option B</em></u></h3><h3><u><em>The equation of a line, in point- slope form, that passes through (5, -3) and has a slope of 2/3</em></u></h3><h3><u><em /></u> $y + 3 = \frac{2}{3}(x -5)$ <u><em /></u></h3>

<em><u>Solution:</u></em>

<em><u>The equation of line in point slope form is given as:</u></em>

$y - y_1 = m(x-x_1)$

Where, "m" is the slope of line

Given that,

slope = 2/3

$m = \frac{2}{3}$

The line passes through (5, -3)

Substitute m = 2/3 and $(x_1, y_1)$ = (5, -3) in point slope form

$y - (-3) = \frac{2}{3}(x -5)\\\\y + 3 = \frac{2}{3}(x -5)$

Thus equation of line in point slope form is found

24=3(n-5) solve for n

mario62 [17]

Answer:

n = 13

Step-by-step explanation:

24 = 3 (n-5)

3n - 15 = 24

3n = 24 +15

3n = 39

n = 39/3

n = 13
