What is -7n-4=24 lol i hate homework
Montano1993 [528]
It's a simple linear equation in 'n'.  There's only one number that 'n' can be
that will make the equation a true statement.  That number is called the
'solution' to the equation.  Here's one way to find it:

You said that                       <u> -7n - 4  =  24</u>

Add  4  to each side:           -7n       =  28

Multiply each side by  -1 :    7n       =  -28

Divide each side by  7 :         <em>n        =  -4</em>

Homework is the only way for most people to learn stuff.

juin [17]

Answer: n-4(32.5) > 300;n > 430tep-by-step explanation:

Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is

Profit > $300

the profit he makes is equal to the amount he is paid - the cost of supplies. The cost of supplies is $32.50 for each room. That is

n - 32.5 and

P + 32.5 × 4

Where 4 = number of rooms

P + 130

n-4(32.5) > 300;n > 430tep-by-step explanation:

given that Zack wants to make a profit of more than $300 for painting 4 identical rooms. That is

Profit > $300

Then, the profit he makes is equal to the amount he is paid minus the cost of supplies. The cost of supplies is $32.50 for each room. That is

n - 32.5 and

P + 32.5 × 4

Where 4 = number of rooms

P + 130

The minimum profit = 300 + 130 = $430

n-4(32.5) > 300;n > 430 430
