Answer:
6x + 1
Step-by-step explanation:
Distribute
3 + 2 ( x- 1 ) + 4x
3 + 2x - 2 + 4x
Subtract
3 + 2x - 2 + 4x
1 + 2x + 4x
Like terms
1 + 2x + 4x
1 + 6x
Rearrange
6x + 1
Cost = 15x + 2000
Earning = 35x
At break even, cost = earning
35x = 15x + 2000
20x = 2000
x = 100
100 rides are needed to break even.
7/12.
Explanation:
Find a common denominator between 3/4 and 1/6. Since both 6 and 4 can go into 12, that will be our denominator.
With 1/6, you have to multiple 6 by 2 to get 12, so multiple 1/6 by 2/2 and you get 2/12.
For 3/4, 4×3=12, so do 3/4 × 3/3 and you get 9/12.
Finally, subtract John's value from Sandy's, or 9/12-2/12 and you get 7/12, so he ate 7/12 more than Sandy.
Hope this helps :)
