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

A meal plan lets students buy $20 meal cards. Each meal card lasts about 8 days. write and graph equation
Luda [366]

Step-by-step explanation:

Given that,

A meal plan lets students buy $20 meal cards.

Each meal card lasts about 8 days.

Let us assume that y denotes number of days for a 20 dollar meal card i.e. $20 every 8 days.

Let x = number of $ for another day.

So,

y=\dfrac{8}{20}x+8

y=\dfrac{2}{5}x+8

Hence, this is the required equation.

Given two functions f(x)=2x+4 and g(x)=−1/5x−3 , what is the function rule for (f+g)(x) ?
Angelina_Jolie [31]

The definition is pretty simple:

(f+g)(x) = f(x)+g(x)

So, we only have to sum the expressions:

f(x)+g(x) = 2x+4 - \dfrac{1}{5}x-3 = \dfrac{9}{5}x+1

The factorization of the numbers is obtained as

(a) 36 = 2² x 3²,

(b) 60 = 2² x 3 x 5,

(c) 84 = 2² x 3 x 7,

(d) 99 = 3² x 11 and

(d) 180 = 2² x 3² x 5

<h3>Factor of the numbers</h3>

To factorize the numbers we use their factors as show below;

<h3>Factors of 36</h3>

36 = 2² x 3²

<h3>Factors of 60</h3>

60 = 2² x 3 x 5

<h3>Factors of 84</h3>

84 = 2² x 3 x 7

<h3>Factors of 99</h3>

99 = 3² x 11

<h3>Factors of 180</h3>

180 = 2² x 3² x 5

Thus, the factorization of the numbers is obtained as 36 = 2² x 3², 60 = 2² x 3 x 5, 84 = 2² x 3 x 7, 99 = 3² x 11 and 180 = 2² x 3² x 5.
