Answer:

3 necklaces and 12 bracelets

Step-by-step explanation:

Bracelets = x +4

amount of necklace gold  =   20*x

amount of gold in bracelet = 7*(x+4)    

added together = 109 gm

 20x    +  7(x+4)     =    109    

20x + 7x+28 = 109

27x+28=109

-28        -28

27x= 81

/27   /27

x=3 necklaces

then bracelets = 3+4=12

From a survey of 60 students attending a university, it was found that 9 were living off campus, 36 were undergraduates, and 3 w
lana66690 [7]
I think the question has to do with the number of students who are attending the university but is neither an undergraduate nor living off-campus. To help us solve this problem, we use the Venn diagram as shown in the picture. The intersection of the 2 circles would be 3 students. The students in the 'students living off-campus' circle would be 9 - 2 = 6, while the undergraduate students would be 36-3 = 33. The total number of students inside all the circles and outside the circles should sum up to 60 students.

6 + 3 + 33 + x = 60
x = 60 - 6 - 3 - 3
x = 18 students

Therefore, there are 18 students who are neither an undergraduate nor living off-campus

Can Some one please help me on these math questions<br><br>I'll give 20 points please
MArishka [77]

Answer:

☐ -2 < 2x + 4

☐ -3x - 2 > 5

Step-by-step explanation:

-3x - 2 > 5

+ 2 + 2

___________

-3x > 7

___ ___

-3 -3

x < -2⅓ [Anytime you <em>divide</em> or <em>multiply</em> by a negative, reverse the inequality symbol.]

-2 < 2x + 4

-4 - 4

___________

-6 < 2x

__ ___

2 2

-3 < x

If you plug in -3 for <em>x < -2</em><em>⅓</em><em>,</em><em> </em>you will see that it is a genuine statement because the more higher a negative gets, the lesser the integer will be, so in this case, -3 IS <em>less</em><em> </em><em>than</em><em> </em>-2⅓.

I am joyous to assist you anytime.

** If it is not multi-select, then choose <em>-2 < 2x + </em><em>4</em><em>.</em>
