Answer:
254
Step-by-step explanation:
If you subtract both numbers, you will find the answer is 254
Step-by-step explanation:
To solve a compound inequality, first separate it into two inequalities. Determine whether the answer should be a union of sets ("or") or an intersection of sets ("and"). Then, solve both inequalities and graph.

Answer:
18 jumps would be expected in a 2 hour period.
Step-by-step explanation:
Given : A dolphin jumps 54 times in a 6 hour period.
To find : At this rate, how many jumps would be expected in a 2 hour period?
Solution :
Applying unitary method,
In 6 hour period Dolphin jumps 54 times.
In 1 hour period Dolphin jumps 
times.
In 1 hour period Dolphin jumps 9 times.
In 2 hour period Dolphin jumps 
times.
In 2 hour period Dolphin jumps 18 times.
Therefore, 18 jumps would be expected in a 2 hour period.
Start by getting one of the equations in terms of one variable, in this case lets put the first equation in terms of y
2x+y=3 ---> y=3-2x
now we plug that into the second equation
5x-2y=12 ---> 5x-2(3-2x)=12
we can then multiply and simplify
5x-2(3-2x)=12 ---> 5x-6+4x=12 ---> 9x-6=12 ---> 9x=18 ---> x=2
we can now plug x=2 into an equation to solve for y
2(2)+y=3 ---> 4+y=3 ---> y=-1
