Answer:
see explanation
Step-by-step explanation:
Given
10 = 7 - m ( subtract 3 from both sides )
3 = - m ( multiply both sides by - 1 )
- 3 = m , or
m = - 3
As a check
Substitute m = - 3 into the right side of the equation and if equal to the left side then it is the solution
7 - m = 7 - (- 3) = 7 + 3 = 10 = left side
Thus m = - 3 is the solution to the equation
Yes, the expression to answer that is 1,000 divided by, the answer is 125.
The second answer.
You have the first prize, x.
Then you have the second prize, which is x - 50.
Then you have the third prize, which is x - 50 -50, or x - 100.
So the total money is:
x + (x-50) + (x-100).
To figure this out, we would need to find the volume of the present.
The formula for finding the volume of an object is LxWxH, so we would multiply 5x8x1.5 to get a volume of 60 inches.
So we would need at least 60 inches or wrapping paper.
I hope this helped! :-)
