Answer:
7/6
Step-by-step explanation:
5/2-4/3
=(5*3-4*2)/2*3
=(15-8)/6
=7/6
4b+2c=36, solve for b, subtract 2c from both sides
4b=36-2c divide both sides by 4
b=9-0.5c
Then we are told that:
7b+3c=59, using b=9-0.5c we get:
7(9-0.5c)+3c=59 perform indicated multiplication on left side
63-3.5c+3c=59 combine like terms on left side
63-0.5c=59 subtract 63 from both sides
-0.5c=-4 divide both sides by 0.5
c=8
So each souvenir cup costs $8.
(and each bag of cotton candy is $5)
First, you have to make the denominators the same.
5 1/3 is now 5 4/12
4 3/4 is now 4 9/12
5 4/12
- 4 9/12
4 16/12
- 4 9/12
7/12
Hope this helps!
