Answer:
9/5C +32 = F
Step-by-step explanation:
C = 5 / 9 (F - 32)
Multiply each side by 9/5
9/5* C = 5 / 9 (F - 32) *9/5
9/5 C = F -32
Add 32 to each side
9/5C +32 = F -32 +32
2. 9a +4c=43
a+c=7
The total tickets for adults and children = 7 (a+c =7) 7 people in all
price for adult = $9 (9a) Price per child =$4 (4c)
total price =$ 43
9a +7c = 43
