Hi there!
Let x=1
X-3y=6
1-3y=6
-3y=6-1
-3y=5
Y=-5/3
Therefore a point would be (1, -5/3)
Hope this helps!
Number of tables al four restaurants have;
= 4 * 30
=120 tables
Two new restaurants + 4
=6 restaurants
(120+15+9)= 144 tables
Mean = total # of tables/ total # of restaurants;
144/6
=24
This is the mean so it decreases. I hope this helps even though you didn’t actually post the number line
Just divide 80 by 7 and see if you don’t get a whole number !
The solution would be like
this for this specific problem:
a + 20 = 5/7 (3a - 20) <span>
a + 20 = (15a - 100)/7 </span><span>
Multiply both side by 7, </span><span>
7a + 140 = 15a - 100 </span><span>
8a = 240<span>
</span></span>a = 30
3a = 90
a + 20 = 50
3a - 20 = 70
<span>5/7 x 70 = 50</span>
