Donations = $10,000
Revenue = $55 per race enry
Expense = $15 per race entry
Budget ≥ $55,000
Let x = the number of race entries.
Total revenue = Donations + Race entries - Expenses
Therefore
10000 + 55x - 15x ≥ 55000
40x ≥ 45000
x ≥ 1125
Answer: Race entries ≥ 1125
Answer:
The teacher have 32 students.
Step-by-step explanation:
Firstly, 'if she gave each students 3 bookmarks, she would have 21 bookmarks left.' This means that 3x + 21 = amount of bookmarks available. Here the x is the number of students.
Then, 'if she gave each students 5 bookmarks, she would be short of 53 bookmarks.' This means that 5x - 53 = amount of bookmarks avalable.
Since both equations all equal to the same quantity, then we know that:
3x + 21 = 5x - 53
Finally, we just need to rearrange the equation to make x the subject.
3x + 21 = 5x - 53
3x = 5x - 53 - 21
3x = 5x - 74
3x - 5x = - 74
- 2x = - 74
- 2x ÷ -2 = - 74 ÷ -2
x = 37
Then, just to make sure, we put the number of students into the equations.
3x + 21 = 5x - 53
3 × 37 + 21= 5 × 37 - 53
111 + 21 = 185 - 53
132 = 132
This means that x does equal to 37.
4 three pointers and 3 two pointers would equal 18 total points If they shoot 4 three pointers than they would have 12 so far, and if they then shoot 3 two pointers then they would have 18, because (4 * 3) + (3 * 2) is 18
Answer:
Add 5 to both sides.
Step-by-step explanation:
3.7 = x + (-5)
3.7 + 5 = x + ( -5) + 5
5 cancels on the right
8.7 = x
