Answer:

n = -10

Step-by-step explanation:

5n = 8n + 30

you move 8n over by subtracting it from both sides

5n -8n = 8n -8n +30

add like terms

-3n = 30

then divid both sides by -3

-3n/-3 = 30/-3

n = -10

To find n
1. Subtract 8n from both side to get -3n=30
2. Divide both sides by -3 to get n=-10

Factor the expression below.
Leni [432]

Answer: B

Step-by-step explanation:

When you factor an expression, you want to take out a factor of the numbers and variables.

Since this expression is a bit hard to factor as itself, we can FOIL the answers to see the correct expressions.

(4x-5)(4x-5)

16x²-20x-20x+25

16x²-40x+25

How can you make 0.40 into a fraction??
melamori03 [73]
<h3>2/5 is your answer. </h3><h3>▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓</h3>

☞ First, 0.40 is the same as 40/100.

But we are not done.

<u>Now, doing this you need to find the GCF (Greatest common factor) of 40, 100.</u>

2 x 2 x 5 = 20.

☞ So our GCF is 20.

Divide both the numerator and the denominator by the GCF.

40 ÷ 20 / 100 ÷ 20.

<h2>Simplify to get ☞ 2/5.</h2><h2>▬▬ι══════════════ι▬▬</h2>

Best of luck on your assignment!
