Answer:
Elena's move will lead to the solution of the problem
Step-by-step explanation:
To solve the equation 7.5d=2.5d, Lin divides each side by 2.5d, and Elena subtracts 2.5d from each side. Will both moves lead to the solution? Explain your reasoning
Given:
7.5d = 2.5d
Lin divides each side by 2.5d, Lin:
7.5d / 2.5d = 2.5d / 2.5d
3 = 1
This can not be the solution to the problem because 3 can not be Equal to 1
Elena subtracts 2.5d from each side
7.5d = 2.5d
7.5d - 2.5d = 2.5d - 2.5d
5d = 0
This can lead to the solution of the problem
Elena's move will lead to the solution of the problem
Answer:
a=$4.00, B=1/4 a pint per dollar, c= 5
Step-by-step explanation:
we are given
speed is 850mi/h
we know that
1 mile =1609.34 metre
1 hour = 3600 second
now, we can replace 1mi and 1hour
now, we can solve it
379.98306
...........Answer
We use BEDMAS and we go from left to right
Therefore; 1. 9+34 = 43
2. 43+5452 = 5495
3. 5495 -49349 = -43854
4. -43854+4 = -43850
Final Answer is - 43' 850.
