Answer:
--- (a)
---- (b)
Step-by-step explanation:
Given
Per ride (r) = $8
Per baseballs (s) = $6
Total = $100
Required
Represent using an equation
If 1 ride is $8.
r rides would be 8r
If 1 baseball is $6
s baseballs would be 6r.
So, total is:

Solving (b):
Value of s when r = 14

Substitute 14 for r


Solve for 6s


Solve for s


Step-by-step explanation:
-10 or -20 satisfies the equation.
But when you substitute 10 in:
30-40<-50+8
-10<-42(wrong)
it's wrong
Answer:
x=9
Step-by-step explanation:
To find the x-coordinate, plug the y-coordinate into the equation and solve from there.
(0 = 2/3x - 6) (6 = 2/3x) (18 = 2x) 9 = x
