Answer:
1) ok, we know that if we divide one number by the same number, the solution is 1 ; this is: a/a = 1
so we could write something as:
3 = 3*1 = 3*(5/5) = (3*5)/5 = 15/5
so 3 = 15/5
this is especially useful when working with addition of fractions.
2) this is really useful if you have a square root in the denominator.
for example : 
3) you also could do this in the next way:
3 = 3*1 = 3*(7/7) = 3*(3+4)/7= 9/7 + 12/7
where i splitted the 7 into 3 +4, this relation could be useful sometime.
4) if you do the difference between some number and the prior number; you get one; this is : (5 -4) =1
then: 3= 3*1 = 3*(5 - 4) = 15 - 12
Answer: i think it's (-4,-10)=m

Answer:
$30
Step-by-step explanation:
Calculation for the tickets that must be purchased for Carnival T and Carnival Q to be the same
Based on the information given let x be the number of ticket to be purchased .
Carnival T entrance fee= $7.00
Ride= $0.50 per ticket
Carnival Q entree fee =12.00
Ride= $0.25 per ticket
Tickets=$7.00 + ($0.50* x) = $12.00 + ($0.25* x)
.25 x = 5.00
Hence:
x=$.25+$5.00
×=$30
Therefore the amount of tickets that must be purchased in order for the total cost at Carnival T and Carnival Q to be the same will be $30
