The question is:  Which method do you prefer ?

First of all, nobody can answer that for you, because it's your opinion and you haven't told us your opinion.

But look at it ! the first method eliminates parentheses right away, and each step is an application of a clear, simple arithmetic rule.  The second method has fractions and parentheses all over the place, and it looks so complicated that even the person who posted the first answer here doesn't completely recognize what's going on.

I know which method I would prefer.  But like it says, the correct answer is a matter of opinion, and my opinion might not be the same as yours.

Well, for method one the first step we have is distribution, then combining like terms, then property of subtraction, then division.  For method two, I'm not entirely sure what they did there.  I've never done math like that.  Sorry I can't help you out all the way.

The graphs below are based on government data on unemployment for 2017.
lord [1]

You already got the first two questions right: the group with the highest number of people unemployed / unemployment rate is the one with the highest bar in the respective histogram.

The two graph are related in this sense: take the first age group as reference. We know that 700 people from 16 to 19 are unemployed, and that those people represent 14% of the population, then we know that the 14% of the population between 16 and 19 is 700.

We can deduce that, if x is the number of people between 16 and 19, we have

\dfrac{14}{100}x=700 \iff \dfrac{7}{50}x=700 \iff \dfrac{x}{50}=100 \iff x=5000

So, by the relation between the two graphs, we can deduce the total population for each age group.

Help Pls! I need this fast!
lesya [120]

Answer: 36

Step-by-step explanation:

\overline{AB} \cong \overline{BC} (Triangle ABC is isosceles)

m\angle CAB=m\angle CBA=30^{\circ} (base angles of an isosceles triangle are congruent)

\angle MCB=90^{\circ} (In triangle CMB, angles in a triangle add to 180 degrees)

\angle ACM=30^{\circ} (triangle sum theorem)

MB=24 (30-60-90 triangle CMB)

AB=12 (sides opposite congruent angles in a triangle are congruent)

AB=36 (segment addition postulate)
