Answer:
(17/8, -1/8)
Step-by-step explanation:
the bottom equation is equivalent to x = 2-y
so I switch the value of x in the top equation to x = 2-y
and it becomes 2*(2-y) - 6y = 5
equal to 4 - 2y - 6y = 5
-8y = 1
y = -1/8
then you substitute this value in the second equation
x + y = 2 becomes x + (-1/8) = 2
x = 2 + 1/8 = 16/8 + 1/8 = 17/8
240 Liters total volume
Let's make ;
x = number of containers
v = volume of one container
vx = 240
v = 240/x
1) a = tickets in advance goal = 2000
d =tickets at door
6a +8d = 2000
6(142)+8d =2000
852+8d=2000
8d=2000-852
8d=1148
d=1148/8
d=143.5
round up d=144 need to sell 144 tickets at door
Answer:
None of the above
Step-by-step explanation:
A proportional relationship is where one ratio is the same as another ratio. For example, the ratio 1:2 is the same as 2:4. If you go ahead and divide both of these ratios, you'll get the same relationship 1:2.
