Answer:
a : b : c = 12 : 10 : 15
Step-by-step explanation:
Given that: b = 
of c
i.e b = 
............... 1
2c = 5b
So that;
c = 
.................... 2
Also,
4a = 3c
a = 
................ 3
⇒ a = 
× ()
a = 
................. 4
15b = 8a
b = 
................. 5
Comparing the derived equations:
From equations 2 and 3,
a:c = : = 4:5
From equations 1 and 2,
b:c = : = 2:3
But a common value of b = 15, gives;
a : c = 12 : 15 and b : c = 10 : 15
Thus, a : b : c = 12 : 10 : 15
She would sold 255 cups.
$127.50÷$0.50=255
(Hope this is correct!)
3.) y-intercept = 2. The graph will be a straight line passing through points (0, 2) and (2/3, 0)
4.) y-intercept = -1. The graph will be a straight line passing through points (0, -1) and (2, 0)
5.) y-intercept = 2. The graph will be a straight line passing through points (0, 2) and (3, 0)
