Answer:
See explanation below
Step-by-step explanation:
a + b = 0
The additive identity establishes that if you add a real number to zero, then you get the same real number back.
The additive inverse of a number x is -x (because x + (-x) = 0)
a+b = 0, but by the additive identity we can add -a (the additive inverse of a) to both sides of the equation:
a + b - a = 0 - a
a + b - a = -a (Now, using the Cancellation property we can cancel a and -a on the left side)
b = -a
1/6 of the muffins is 3 muffins with nuts. So you multiply 3 by 6 to get 18 muffins in all.
Answer:the percent change in the puppy's weight= 275%
Step-by-step explanation:
Jillian's puppy Weight at 2 months =16 pounds
Jillian's puppy Weight at 8 months =60 pounds
percent change in the puppy's weight= change in weight / Old weight x 100
(60 pounds -16pounds ) / 16 x 100
44/16 x 100 = 275%
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
C.) is the answer, I think
