Answer:

n=8

Step-by-step explanation:

2(5-6n)=10n-166

1) Distribute the 2 to 5 and -6n:

10-12n=10n-166

2) Add 166 to both sides:

176-12n=10n

3) Add 12n to both sides:

176=22n

4) Divide both sides by 22:

n=8

In 2010, a city's population was 1,405,233 and it was decreasing at a rate of 1.1%. At this rate when will the city's population
frez [133]
The equation
                                            P(t) = 1405233 * (1 - 0.011)^(t)
models the population at t years after 2010. Then, when P(t) = 1,200,000, we have
                                 1200000 = 1405233 * (0.989)^t
                                  (0.989)^t = 1200000/1405233
                                                t = log(1200000/1405233)/log(0.989)
                                                t = 14.27 years
This means 14.27 years after 2010. Therefore, the answer to this question is 2024.

<h3>Answer:   ASA</h3>

Explanation:

The arc markings for each angle show that we have two pairs of congruent angles (angle O = angle Q, angle M = angle R). This takes care of the two "A"s in "ASA". The tickmarks show us that the sides MO and RQ are the same length, so this takes care of the "S" of "ASA". Note the congruent sides are between the angles mentioned. The order is important.

I do not understand this math problem I have to do. It is 32-6x=20 and I need to find the variable but it's too confusing for me
sineoko [7]

Answer:

The answer to your question x=2.

Step-by-step explanation: So, first you simplify both sides of the equation which, would look like this after, -6x+32=20. After that, you subtract 32 from both sides which will look like this after -6x=-12. Then you would divide each side by -6 which will get x=2. Hope this helps!

What is the solution to 5a - 15 + 9a = 3a + 29?
grin007 [14]
Hi there! Thanks for asking a question here on Brainly. 

Step 1: We need to simplify both sides of the equation.

⚫ <span><span><span><span>5a</span>−15</span>+<span>9a</span></span>=<span><span>3a</span>+29
</span></span>⚫ <span><span><span><span><span>5a</span>+</span>−15</span>+<span>9a</span></span>=<span><span>3a</span>+29
</span></span>⚫ <span><span><span>(<span><span>5a</span>+<span>9a</span></span>)</span>+<span>(<span>−15</span>)</span></span>=<span><span>3a</span>+29
</span></span>     
Combine like terms

⚫ <span><span><span>14a </span>+<span>15 </span></span>= <span><span>3a </span>+ 29
</span></span>⚫ <span><span><span>14a </span>− 15 </span>= <span><span>3a </span>+ 29

</span></span>Step 2: Subtract 3a from both sides.

⚫<span><span><span><span>14a </span>− 15 </span>− <span>3a </span></span>= <span><span><span>3a </span>+ 29 </span>− <span>3a
</span></span></span>⚫<span><span><span>11a </span>− 15 </span>= 29

</span>Step 3: Add 15 to both sides.

⚫ <span><span><span><span>11a </span>− 15 </span>+ 15 </span>= <span>29 + 15
</span></span>⚫ <span><span>11a </span>= 44

</span>Step 4: Divide both sides by 11.

⚫ 11a11= 4411

a = 4
