Step-by-step explanation:
(60mph+20mph)/2
40
What I would do for this problem, is move all the terms that don't contain m to the right side, and then solve.
m = 4/5.
I am going to do number 2 so when you subtract decimals you have to add two zeros like this 10.00 or 0.25 so now when you subtract you get $9.75
Area of a parallelogram = base x height
So, 10.5 x 7 = 73.5
1. 1/5 = x - 9 / x
2. Cross multiply x = 5 (x - 9)
3. Distribute x = 5x - 45
4. Move the variable and change the sign x - 5x = -45
5. Add like terms -4x = -45
6. Divide x = 45 / 4
So the solution is x = 45 / 4 or 11.25
