Answer:

D or 14 x (2+5)

Step-by-step explanation:

Answer A has 14 as a factor, but that's not what the question is asking for. So, we cannot choose this option.

Answer B has 7 as a factor, so we cannot choose that.

Answer C has 2 as a factor, so we can't choose this option.

Answer D (the correct answer) does not have any factor, so we can choose this.

Therefore, the correct answer is option D. Hope this helps!

There are 364 students who are enrolled in an introductory biology course. If there are five boys to every eight girls, how many
Butoxors [25]

Answer:

The number of boys in the course will be = 140

Step-by-step explanation:

Given:

Total number of students enrolled in an introductory biology course = 364

There are 5 boys to every 8 girls in the course.

To find how many boys are in the course.

Solution:

Since, there are 5 boys to every 8 girls in the course.

So, ratio of boys to girls enrolled in the course = 5 : 8

Let the number of boys in the course be = 5x

Then number of girls in the course will be =  8x

Total number of students would be given as:

⇒ <em>Number of boys + Number of girls</em>

⇒ 5x+8x

⇒ 13x

Total number of students given = 364.

Thus, we have:

13x=364

solving for x

Dividing both sides by 13.

\frac{13x}{13}=\frac{364}{13}

∴ x=28

So, number of boys in the course will be = 5\times 28 = 140
