Answer:

The systems of equation are identical and such there are infinitely many solutions. For the first part the correct answer is B. For the second part, the correct answer is A

Step-by-step explanation:

If we multiply the first equation by 4 the result is the second equation and thus the systems of equations are scalar multiples of each other. The solution to such a system is found by expressing one variable in terms of the other hence choice B.

Since the systems are scalar multiples of each other, if we graph them they would simply coincide since they are identical, that is they have same slope and y-intercept.

Maslowich

Answer:

If a person selected at random from this group is a man, there is a 31.25% probability that the person favors raising the drinking age.

Step-by-step explanation:

We have these following informations:

There are 1000 people in total.

540 favored raising the age. Of them 390 were female, and 540-390 = 150 were male.

460 were opposed. Of them, 130 were female and 460-130 = 330 were males.

If a person selected at random from this group is a man, what is the probability that the person favors raising the drinking age?

There are 150+330 = 480 males. Of them, 150 favors raising the drinking age.

$P = \frac{150}{480} = 0.3125$

If a person selected at random from this group is a man, there is a 31.25% probability that the person favors raising the drinking age.

It was divided by 2 so it can be the amount the bracelets cost. Or instead of dividing to get 250, You can multiply and do 2x125=250, So them add Go on from there, Its not to hard but if you need more help I'm here!

Now for the necklace portion of it. 3x80=240, So she sold 80 necklaces. Than sold 3 more. Now you have a total of 250.
