Solve 5n + 6 = -3n - 10

Verizon [17]

Hi there! :)

Answer:

$\huge\boxed{n = -2}$

5n + 6 = -3n - 10

Solve for n:

Add 3n to both sides:

5n + 3n + 6 = -3n + 3n - 10

8n + 6 = -10

Subtract 6 from both sides:

8n + 6 - 6 = -10 - 6

8n = -16

Divide both sides by 8:

8n/8 = -16/8

n = -2.

Please help ASAP will mark brainiest

yawa3891 [41]

Answer:

Yes, they are proportional.

Step-by-step explanation:

Using this from what I found helped me answer the question, and if you compare their ratios, they are both going to show that 75% each class have texted:

Proportional: When quantities have the same relative size. In other words they have the same ratio.

All you would have to do is compare the amount of students that texted(x) to the amount of students there are total in the class(y). When you compare them in a y:x format, it will all lead up to the results showing that 75% of both groups have texted.

There are two spinners. The first spinner has three equal sectors labeled 1, 2, and 3. The second spinner has four equal sectors

zhuklara [117]

<h3>Answer: A) 1</h3>

=========================

Explanation:

Let's label each pair of outcomes as an ordered pair (x,y)

x = first spinner outcome

y = second spinner outcome

We have these 12 different possible combos

(1,3), (1,4), (1,5), (1,6)

(2,3), (2,4), (2,5), (2,6)

(3,3), (3,4), (3,5), (3,6)

Focus on the third column where y = 5 for each (x,y) pair. Of this column only (2,5) has x be an even number. The other results in that column have x be odd.

Basically (1,5) is the only possible outcome if we want the first spinner to lan on an even number, and the second spinner to land on 5.
