Answer:

There are 240 boys.

Step-by-step explanation:

There are five boys to every three girls in an introductory Chinese course. Given that there are 384 students enrolled in total, we want to determine the amount of students which are boys.

Let <em>b</em> represent the number of boys and <em>g</em> girls.

Since the ratio is 5:3, we can write that:

$\displaystyle \frac{5}{3} = \frac{b}{g}$

And since the total number of students is 384:

$b + g = 384$

From the first equation, cross-multiply:

$5g = 3b$

Solve for <em>g: </em>

<em /> $\displaystyle g = \frac{3}{5} b$ <em />

Substitute:

$\displaystyle b + \left (\frac{3}{5} b\right) = 384$

Simplify:

$\displaystyle \frac{8}{5} b = 384$

Solve for <em>b: </em>

<em /> $\displaystyle b = \frac{5}{8}\left(384\right) = 240$ <em />

<em />

In conclusion, 240 of the total students are boys.

The sum of a number times 7 and 21 is at least 29. Write as an inequality

PtichkaEL [24]

The inequality is 7x + 21 $\leq 29$

Step-by-step explanation:

<u>DATA:</u>

Let the number be x

Number times 7 = 7*x

Sum of a number times 7 and 21 = 7x + 21

Is at least 29

<u>INEQUALITY:</u>

7x + 21 $\leq 29$

<u>SOLVE:</u>

7x $\leq 29-21$

7x $\leq 8$

x $\leq \frac{8}{7}$

Therefore, the inequality is 7x + 21 $\leq 29$
