Answer:

<em>There were 204 ladies and 136 gentlemen in the conference</em>

Step-by-step explanation:

Let's set the variables:

L = number of ladies in the conference

G = number of gentlemen in the conference

We know 340 people participated in the conference, thus:

L + G = 340         [1]

We are also given the ratio of ladies and gentleman as 3:2, thus:

L/G = 3/2

Cross-multiplying:

2L = 3G        [2]

From [1]:

L = 340 - G

Substituting in [2]:

2(340 - G) = 3G

Operating:

680 - 2G = 3G

5G = 680

G = 680/5 = 136

G = 136

L = 340 - 136 = 204

L = 204

There were 204 ladies and 136 gentlemen in the conference

In a function, X does not repeat.
Your answer is A.

<span>a (1,2) (2,4) (3,5)
</span>there are different x values for
each point, so this IS A FUNCTION.
<span>
b. (1,2) (2,3) (1,5)
</span>there are two values of x being 1,
so this is NOT A FUNCTION.

<span>c. (1,2) (2,4) (2,6) 
</span>there are two values of x being 2
so this is NOT A FUNCTION.
<span>
d. (1,2) (3,5) (3,7)</span>there are two values of x being 3,

Helena is baking a cake that requires three and one-half cups of flour. Helena accidentally poured five and one-sixth cups of fl
RUDIKE [14]

Amount of flour Helena accidentally poured =5\frac{1}{6} =\frac{31}{6} cups of flour.

Amount of flour the cake requires =3\frac{1}{2} =\frac{7}{2} cups of flour.

Amount of flour that Helena should take out =\frac{31}{6} - \frac{7}{2}

                                                                          =\frac{31}{6} - \frac{7 \times 3}{2\times 3}

                                                                          =\frac{31}{6} - \frac{21}{6}

                                                                          =\frac{31-21}{6}

                                                                          =\frac{10}{6}

                                                                          =\frac{5}{3}

                                                                          =1\frac{2}{3} cups of flour.
