Answer:
-2
Step-by-step explanation:
The equation is -12/c=6
by solving for c you get,
-12/c=6
Then multiply both sides by the LCM c to get, -12=6c
Divide both sides by 6 to get,
-12/6=6c/6
-2=c
Verification:
-12/-2=6 since when a negative number divides a negative number the answer is a positive value
An expression that represents the total calories for ‘n’ Big Macs is:

Answer:
Ravi’s average speed is 7 miles per hour
Step-by-step explanation:
In this question, we are tasked with calculating what Ravi’s average speed was.
We must know that the term average speed is mathematically equal to Total distance/ Total time
We already have the time of 3 hours, what is needed is the distance.
From the question, we can see that they met at the point where Pilar had travelled 55 miles. What this means is that Ravi would have traveled (55-34) miles to this point since they are coming in opposite direction. This means that Ravi had traveled 21 miles
Thus his average speed is 21 miles/ 3 hours = 7 miles per hour
