Answer:
the price for one pretzel was $1.75
Step-by-step explanation:
d for drinks
p for pretzel
3d + 3p = 9
3d = 9 -3p
d = 3 - p
replace d = 3 - 9 into 4d + 2p = 8.5
4d + 2p = 8.5
4(3 - p) + 2p = 8.5
12 - 4p + 2p = 8.5
-2p = 8.5 - 12
-2p = -3.5
p = 1.75
Answer:
-1/3(x+36)
Step-by-step explanation:
When the second number is divided by the first, the result is ...
First table
9/3 = 3
12/4 = 3
20/5 = 4 . . . . result is not consistent. NOT a proportional relationship
Second table
25/20 = 1.25
30/24 = 1.25
40/32 = 1.25 . . . . result is consistent. A PROPORTIONAL RELATIONSHIP
Third table
12/4 = 3
15/5 = 3
24/6 = 4 . . . . result is not consistent. NOT a proportional relationship
Fourth table
4/3 ≈ 1.33
9/6 = 1.5
16/12 ≈ 1.33 . . . . result is not consistent. NOT a proportional relationship
